Firescale and Oxidation

Removing Firescale and Oxidation

Question

You state you: leave too many “fire marks” – what do you mean by that?  Are you using pickle to clean the metal after soldering?  Or are you seeing that gray bruising after polishing (firescale)?  If you are seeing firescale, try doing something like what is in this Rio Grande article. If you have oxidation from soldering, try a nickel pickle:  Here’s one article from Hoover and Strong. Here’s a product – Rio Clean Pickle – designed for nickel, brass and bronze.

Answer

For getting into all the nooks and crannies, try the 3m Radial Bristle Discs.  They work great!  To learn more about finishing please view my webpage: Finishing Jewelry and my video: How To Finish Jewelry.

Protecting Sterling Silver from Oxidation

Question

“Should I be finishing the metal (sterling silver) to prevent further discoloration? What’s the best way to do that? Do you have any videos that address that question?”

Answer

The oxidation is not going to stop unless the metal is sealed – which I don’t recommend. Although, it is fine for necklaces and brooches, sealers wear off very quickly on bracelets and rings – due to the amount of wear and tear.  Protectaclear by Everbrite is one that I am familiar with.  (Although, I am checking out powder coating as a solution – see last paragraph.)

The type of finishing you do,  prior to adding the patina, doesn’t affect the amount of oxidation in the future.  Silver just tarnishes – even fine silver and Argentium but, fine and especially, Argentium, tarnish the least.  You might try working with Argentium  – it really is a lovely material and tarnishes very slowly.
Another idea is to store and sell your work with an anti-tarnish bag.  Rio Grande sells them.  They reduce the tarnish  A LOT.  Also, keeping the metal in an airtight bag reduces the amount of exposure that it gets from the air.  Air is filled with chemicals that affect the rate of oxidation.
Did you see the recent article in Art Jewelry Magazine on powder coating? It was in the January 2016 Issue. (See video with Michael Dale Bernard.)  You can powder coat with a clear coat.  Powder coating is very long lasting – the same paint that is on a car. You might want to check it out.

How to Finish and shine bronze

Question

” I would like to ask how do i finish bronze? To make it shinier? I have recently started with metalwork and i have trouble finishing.”

Answer

Hi ***, have you seen my video on finishing?  I also have a webpage on this subject.  Bronze is finished in a similar method to silver.  The important work is in the pre-polishing.  The surface needs to be free of scratches, nicks, dings and any other marks that you don’t want.  This is achieved using sand paper from 320 grit  (depending on how bad the marks are) through 1000 – 3000. Mirror finishes are very time consuming and involve a lot of elbow grease.

I have a video on finishing and one on sanding: Part One and Part Two.  I also have a web page on Finishing.  Hope this helps. Back to Table of Contents.

How to finish copper, as well as brass jewelry

Question

“I would love to make some copper as well as brass jewelry, but I don’t know what I would use to finish the pieces. Can you recommend any type of clear finish that I can coat my pieces in that is safe for the skin? I work out of my apartment, I do not have studio.”

Answer

Below, is some information from my website:  nancylthamilton.com. This is from my finishing page.

I never seal my jewelry but, many do.  I’m not thrilled with varnishes because, eventually, they crack off.  But, varnish also keeps fingers and wrists from turning green – it’s a tough call.  There are many products out there.  I like ProtectaClear from EverBrite.  Rio Grande carries another type called Midas Finish Seal Lacquer.  But, I haven’t tried this product so, can’t comment on it.

I am going to experiment with powder coating to seal jewelry.  They (you know, “those” people) make a clear – both shiny and matt – powder for powder coating.  I’ll post the results when I try it out.

You could also try Renaissance Wax BUT, it doesn’t last long at all – especially with rings and bracelets.  On earrings and necklaces it will last longer because there is less wear and tear with these items of jewelry. Renaissance Wax is best used on protected areas – to preserve a patina or inhibit oxidation.  I’ve also read that hair spray will slow down oxidation but, it’s not permanent.

Here’s a link to a discussion board from Finishing.com – which is a great resource BTW! – that talks about sealers for metal.

Sealers

  • Everbrite’s ProtectaClear – This is the only lacquer/varnish type that I can recommend at this time as it is the only one that I tested and found to work.  I tumbled pieces for hours and scratched them up with sandpaper.  Although, eventually, the finish got milky (I’d get milky too if I had to suffer the same abuse), the stuff stayed on!  The spray on varnish that I used, peeled up within a half hour.  I also tested it with Liver of Sulfur colors and they stayed true.  Heat treated colors stayed true too (sounds like a song lyric: ♫She stayed true too, oh Honey Boo Boo♫  Like it? No? Oh well…) .  Just remember that the colors will look different, as they are now shiny.
  • Renaissance WaxLiver of Sulfur colors changed.  Leaves a nice, not too shiny finish on the metal.
  • Car Wax – about the same results as with the Renaissance Wax.” Back to Table of Contents.

Question

How Do I Take Off The Scratches From Copper Earrings Using Different Sanding Grits?

I am using 18 gauge copper sheet, pierced and sawed in a pair of earrings.   To finish them I followed the same process I use with silver:  Sanding with three grades of snap on sanding discs from Rio, then onto the 3m radial bristle discs in descending order. But none of the 3m discs will take off the scratches from the last grade of sandpaper. Clearly, I am missing one or more abrasives to use between the sanding discs and the polishing discs.  I have tried all my different grades of wet/dry sandpaper, wire brush, rubber wheel, and various dremel surfaces to no avail.  I assume my usual methods aren’t working because copper is softer than silver.   I have refinished the pieces so many times that my 18 gauge copper is now measuring at 25 gauge!  Which is actually kind of cool and delicate, but I fear it won’t take much more working before it falls apart.  Do you have any advice for me?

Answer

I usually use a minimum of 6 different grits for finishing everything.  250, 350, 400, 600, 800, 1000 and higher sometimes.  I make my own sanding discs with 3m’s PSA discs. I have a lot of information on how I do this on my website.

My thoughts are that you need to go through more grits.  Sometimes, I use just regular sandpaper, sanded in one direction to get an idea of whether or not I need to go back a grit or two.  Run something like 600 g over the metal and see how deep the scratches are – that will tell you what grit to go back to.

As you no doubt know, unless the prior grits marks are removed, all subsequent grits will not remove them.  You have to go back and redo it.  I am actually surprised that you didn’t have the same problem with your silver.  Have you ever photographed a piece and zoomed in on it to see how well it is finished?  It’s frightening – using zoom!  I’ll think I’ve done a great job, zoom in and find out that I hadn’t!  This technique is great for stone setting too.  But, be careful of getting too crazy about perfection.  My husband calls it “good enough to sell”.  If you can’t see it with your eye – it’s probably okay.  But, it does make one strive for machine like perfection.  I have a love/hate with it.  I just bought a microscope and boy, is that scary! Back to Table of Contents.

How do you finish gold?

Question

I have a question: this is the first time that I tried to buff my jewelry using a brown and a red rouge, with the flex shaft, using a felt wheel. After I buffed it, my jewelry changed color from deep yellow to light yellow. Can you help me with this?

Answer

You didn’t mention what type of metal you were using so, I’ll make some guesses.  I think that your metal (gold, brass or bronze) didn’t really change color. I think what happened was that you took off the patina that formed there, over time, and exposed the true color of the metal.  Unless, it was plated, like gold plate* (see below).  That’s a different story.

You have a few options if you want that bright yellow back – but there are no guarantees that it will look exactly the same – patinas have a will of their own.  So, below are a few options:

  • Wait – time (and the chemicals in the air) will patina it again
  • Use a patinating product like these at Sculpt Nouveau.
  • Heat, either from a hot plate or from a gas torch, will also color the metal a bit darker – it can also add many other colors. See this page at Brynmorgen.com for heat patinas.
  • See recipe numbers 15 and 16 at The Science Company’s website. The recipes are to make straw and yellow patinas. The Science Company also sells chemicals to compliment their recipes.

Test all patinas on scrap metal first.  Prepare your metal to make it the same color as your final piece.  Be sure to clean off all grease, oils and dirt with hot water, degreasing soap (like Dawn Dish Detergent) and a soft OLD toothbrush.  Obviously, you are never using that toothbrush again for your teeth!  You can also rub the piece with rubbing alcohol too but, it shouldn’t be necessary.  Water should sheet off of the metal and not ball up.

*If your metal was gold plate, you probably buffed off a layer of gold. By reducing the depth of the gold, the metal underneath (which is usually silver or gold in color) dilutes the depth of the original color making it appear “whiter”. Please see my Patinas, Cleaning Metal and Sculptnouveau webpages for more information. Back to Table of Contents

Protecting the finish on metals

Question

Hi i have a silver figaro necklace and i have watched your video on youtube (how to finish jewelry) and i saw that you sanded a silver necklace and buffed it with the rouge compound and then you suggest finishing it with the LUXI Super Fine White Polishing Compound. I was wondering if it will be the same as what you would get from the jewelry store if not is there a special liquid to give it the stunning shine and prevent it from tarnishing as fast? I noticed you mentioned something about the ProtectaClear at the end of your video but you only said copper or brass. Would i use that for sterling silver? Or is there something better for protecting it and giving it the shiny finish? And also what kind of brush would be the least noticeable if it needs to be brushed on?

Answer

The ProtectaClear can be used on silver too.  Many jewelers use a tumbler to shine up their chains.  Personally, I believe the best way to keep a chain shiny is to wear it or clean it once in awhile.  There is a new type of silver out called Argentium  (also see my webpage “Wire and Sheet Metal”, scroll down to Argentium Silver) which takes years to tarnish.  You can purchase Argentium chains from places like Rio Grande (my main supplier). The finish that is done in manufactured jewelry involves large processing plants and vats of stuff which I have no understanding of.  For the small jeweler you can use Renaissance wax, a product like ProtectaClear or even a spray-on varnish.  The problem with the coating is that eventually, that coating will chip off and then you’ll have to strip it and recoat it – the main reason that I don’t usually use a protective coating.  As for brushes, ProtectaClear comes with this applicator that looks like a powder puff.  I’ve used sponge brushes too.  Apply according to directions.

To clean Argentium silver, if it is tarnished, spray with Windex (or wet a rag with Windex)  and wipe.  Then wash with soap and water.

Can the rouge I use for buffing gold be bad?

Question

“What I am buffing is 90% gold and I don’t think it has patina in it. Do you have another solution about my problem? I did some research about the rouge I use and some people said that the rouge I used was bad. Is it possible that rouge can do this? I used Silverline rouges. This is first time my store has used buffing wheels for jewelry making.  My uncle used to polish gold jewelry with a burnisher and soapy water.”

Answer

So, your gold is 22K.  The rouge shouldn’t be a problem – if it is 22K gold, it should look like shiny 22K gold, after polishing – not change color.

There is a process called depletion gilding where the higher karat gold is pulled to the surface by heat or chemicals.  Usually, the layer of higher karat gold is very thin. Depletion Gilding would make the gold appear yellower.  Buffing with rouge would take off that higher karat layer and leave behind, a lower carat metal.

That said, Golds under 24 karat can oxidize – it depends on what is in the air/environment around you.

  • Here is a quote from Chris Corti at Ganoksin (link is to the whole article): “Blackening of High Carat Gold Jewellery in India and the Middle East”.

“Reports of blackening of 21 and 22 carat gold have been received from customers in countries such as India. This is very unusual in that such blackening is usually found only in low-medium carat golds and is attributable to tarnishing (see below). It is normally considered that high carat golds (such as 22 carat) do not tarnish in the conventional sense. It is a problem that is peculiar to India and other countries in the Middle East, apparently.

Recently, World Gold Council has had an opportunity to examine examples of blackened 22 carat gold returned to retailers in India. The analysis of the blackened layer has shown that it comprises silver (and copper) sulphide. This is a true tarnish layer. That such high carat golds should tarnish is unexpected and points to the jewellery being exposed to a particularly ‘corrosive’ environment at some stage. Perhaps, it is due to being worn during food preparation (some foods & spices are very high in sulphur compounds). Maybe, the jewellery is stored in aggressive sulphur-containing environments. Maybe, the jewellery surface is more susceptible to tarnishing for some reason. At present we cannot be certain as to the cause; we can only speculate. Certainly, the evidence suggests that lifestyle or the local conditions in countries such as India are different from other parts of the world as the problem is not reported elsewhere.

We can say that the jewelry examined was not under-karated or defective in any significant way. Therefore, the manufacturer does not appear to be responsible for the appearance of this blackening effect (tarnish).

If blackened jewellery is returned to the retailer, he should be able to clean off this black layer and re-polish it. Some advice on minimising its occurrence is given above.”

This blackening they are talking about, might start with a general darkening of the metal and your Uncle’s treatment for polishing, would not remove the tarnish but, work it into the metal by “burnishing” it in to the metal.

  • Is there mercury in the buffing compound or nearby (I hope not, it is very dangerous)?  Mercury can change yellow gold and make it look like silver. The quote below is from Finishing.com.  It is an answer to a person whose wedding ring went from gold to silver looking after exposure to mercury:

“A. My suspicion is that mercury is the culprit. Mercury forms a silvery colored amalgam with gold, ruining it. A quiet area in the back of a drawer which once had a bit of mercury in it from a broken thermometer, can have an accumulation of mercury gas. This would quickly turn the gold silvery, but if there was only a tiny exposure, I think the balance of the gold can diffuse to restore the gold color.”

  • Also, see this link to how to fix the color if it was exposed to mercury.

So, I would first check that the gold is actually what it should be.  Check with other jewelers to see if they have a tarnishing problem. It would be interesting to see if the gold turned yellow again, if left to sit.  Then you would know that it is something in the environment that is changing the color. Maybe try using the torch to burn off anything that might be on it – like mercury.

What compound should I buy for 22k gold polishing

Question

“Do have any suggestion for what compound I should buy for 22k gold polishing? I read about depletion gilding article, you gave me, and I think my uncle used this method for polishing. He used to “clean” his work with boiling water with some potassium with salt. Next, he used some sort of burnisher to polish it, on his work surface, to get mirror finish. My question is, can I combine his method and the buffing method with rouge? I tried, but I failed, because it looks like the rouge changed the color again.”

Answer

One company suggests white rouge.  Here is their chart. But, others don’t mention it for gold.  Zam is another product you can try. I have used it with good results.  There are sooooo many different types and brands.  This article might help too.  Otto Frei has many compounds.  Otto Frei says that the Blue Rouge is very popular for polishing gold in Europe.  Here’s another page with information.

I use red rouge for polishing gold and have never had that big of a color change.  Maybe you should find a different rouge supplier or find out what is in it.  If there is mercury in it, it is very, very dangerous for you!  I don’t know who the suppliers are in your country so, I can’t tell you anything about your product.  In the states, we have a thing called an MSDS, which lists the chemicals in the product.  Do you have something similar? Back to Table of Contents

How To Clean And Polish In Tight Spots

Question

“I’m trying to learn how to make  conchos for my horses. Three of them are silver and the other one is Nickle. Im having trouble finding something to clean and brighten inbetween the stones. I either scratch the stones or can’t get it clean and bright enough.”

Answer

I use a variety of tools for reaching into small places.  You can use abrasive tapes and cords, abrasive pins, abrasive discs and points, radial bristle discs, etc.

I would rub a bit of tape over the stone and cut along the interior bezel wall with a scalpel. This will help to protect the stone while finishing.  You can also put your thumb, from your non-dominant hand, over the stone while finishing.

Here’s a little video: Protecting a Stone While Finishing on the tape technique. Back to Table of Contents

How To Protect A Finish And Keep The Coating From Clogging Holes

Question

“I am wondering, about sprays for jewelry making: sprays that prevent tarnish on Brass and copper.
No matter what I’ve tried, I seem to get tarnish anyway or/and pebbly finish and the holes of dangles, plugged.
How do you go about solving this problem. If I coat things before putting together, I often have to redress holes.”
Answer

Well, I don’t usually spray anything.  I feel that the tarnish is what makes the metal beautiful plus, all those coatings wear off over time and then the piece needs to have the finish removed and re-applied.  Not so much for earrings and necklaces though but, rings and bracelets take so much abuse that the finish wears fast. I have applied a protective finish to elements in a bracelet or ring but, I usually set the coated piece in a bezel or some other protective mechanism, that keeps it away from wear and tear.

Look into powder coating with clear – shiny and matte – powders.

 That said, I realize that my opinion is not the only opinion in the world – nor does it matter much to others!   Knowing this fact, I figured out that jewelers needed a solution to their problems.  So, I did some research.  I tested a product by EverBrite:  ProtectaClear.  It works, lasts a long while and is crystal clear.  There are other great products out there but, I didn’t test them all.  Here’s a link to Finishing.Com‘s site for other ideas. Even though they are discussing big stuff like, furniture, you might just pick up a few new ideas! It’s also a great resource to have on hand.

I achieved a smooth, glass-like finish on my test pieces.  enameling-stilts-metalliferous  You can use enameling stilts as drying racks.  Coat one side, let set, then coat the other side, the next day.  Ensure that the product doesn’t slink over to the back side – clean that stuff up, immediately!

I have two pages that relate to finishing for your edification:  Q&A:  Finishing and my main Finishing page  (links are to issues specific to your questions).  Hopefully these pages will help.
As to your problem with clogged holes, can you just drill them out (with a new, sharp bit) after finishing (and the coating has set for at least 24 hours) and then put in the wires?  I don’t see a lot of other choices as the stuff does like to coat and cling.  Maybe you could put wax plugs in the holes, spray or coat with the sealant, let the finish set and then place the pieces on a warm hot plate or in a toaster oven (on tin foil to catch the melted wax) to melt the wax?  You might even be able to just pop them out with a scribe or other slender object.  I’d check them often and definitely experiment first!
round-wax-wire   You can purchase wax wire in many gauges. Many jewelry suppliers carry wax wire in different gauges. Either purchase a range of gauges, like in the link above, or purchase a single gauge.  Match the gauge of your drill bit, that made the hole in the first place, with the gauge of the wire.  I don’t know if this is a stupid idea or not.  I hope you’ll let me know!
I am thinking that some type of resist will work.  I would experiment with scrap first!  Well, that’s all I’ve got.  Sorry.

The joy and frustration of being a jeweler is encountering insolvable problems and working out solutions.  If a problem bothers us enough, we’ll figure out a way around, through or over the issue.

What compounds should I use?

Question

You said in the video that you use red rouge even though you’re supposed to use white. I have only green rouge and platinum white. Would they be sufficient for polishing and finishing my gold jewelry? Also, my rings have scratched that I’m trying to get rid of so I was wondering which rouge should I use FIRST to get the scratches out? I’m guessing Brown Tripoli?? (Although I currently don’t have it) I’m trying to make my rings look brand new, scratch-free! 😀
Also, I have the Foredom flex shaft, the same as yours, and I was also wondering what rotary accessories you would recommend for POLISHING and FINISHING jewelry.

Answer

I only use red rouge.  The pre-finish is, what I feel, is the most important.  I sand with sandpaper or sanding discs from 320 grit up to at least 1200 grit – often higher –  and then I employ the rouge.
You can employ a pre polishing compound, like brown tripoli or bobbing compound  first and then move on to a final finish compound like jeweler’s rouge.
There are so many types of compounds that do the same job, to the same metals but, have different names.  It seems that every company comes up with their own special brand.  I started getting too confused and decided to just stick with the rouge.  It does the job for me.

 As to your other polishing compounds, I would check with the manufacturer or read the label as to their uses.  Determine whether your compound is:  1.  Either an abrasive or a polishing compound and 2. whether or not it is suited for the type of metal you are using.  Test the compounds before using on a final piece.  See the chart in the burring and polishing compounds link below.

Be wary of mixing compounds on the same wheel or using old buffs and wheels as abrasive compounds could be mixed together with polishing compounds.  That can generate a lot of cleanup work.  I use one wheel with one type of metal, with one compound.  I keep the wheel and the compound, together, in their own plastic bag.  It makes it easier to remember what is what.

Another consideration:  If you are pushing out 100 pieces and need a fast finish – compounds, on a wheel or tumbling are much faster than hand sanding.  So, perhaps, compounds are what you need.  You didn’t mention how many pieces you were trying to finish.
 If you are interested, here’s an article from Ganoksin on mass finishing. The article mainly deals with tumbling though so, maybe it’s not what you want.
I highly recommend  the following article, written by John Fisher, called:  Buffing and Polishing compounds.  It is very well done and explains so much.   I found this article on Ganoksin’s site also. I think you will learn a lot from this article!
Whatever you do, – buy from a trusted supplier –  as quality and grit will vary from type to type.  I use Rio Grande’s Sunsheen red rouge because, it is consistent and I know what to expect from it.
Have you been to my web page:  Finishing Jewelry?  I have a lot of information there as well on my Q&A: Finishing page  (I just added your question to that page! – no names used!).  I use muslin and felt buffs, generally, with my flex shaft. I like the loose weave (they are fluffier) for some jobs – usually those with texture and a lot of nooks and crannies and I sometimes use a felt wheel for smooth surfaces or for removing scratches from stones (in tandem with diamond paste).
 I also have a buffing wheel that I use various wheel types on.  I like 3M’s Gray Deburring Wheel and the MX 6 polishing wheel too. I like 3m’s Radial Bristle Discs (for both the flex shaft and my buffing wheel) for textured surfaces.  I use silicone points, knife-edged wheels and other shapes for other types of finishing – like getting into tough spots.  And so much more.  Please see my webpages for more links!
On cleaning up your scratches:  it all depends on how deep they are.  If they are very deep you might have to use files.  But, I’d start with sandpaper.
I have a friend who only uses abrasive wheels to finish her jewelry, another who only uses the buffing wheel, another swears by tumbling.  I say: whatever works for you!
I guess my answer is: the job will dictate the tool!
Thank you for your kind words and I hope that my answers prove useful to you.
Much luck and happy creating!  Nancy

Question

How to finish edges and interior pierced areas.

The edges and interior spaces, on my pierced earrings, look raw.  What do I do to round them and make them look sexy like yours..lol?

Answer

You need to use files and sandpaper!

Make yourself a sanding stick. Or use these flexible sanding sponges.

Watch my two videos on sanding.

I have made sanding sticks using double stick paper, craft foam and craft sticks.  You can also make the sticks without the foam.  The foam helps to make rounded edges as it gives a bit.  It’s easier for curves.

Sanding stick with foam

  • Cut the tip off of the stick
  • Measure stick width and length.
  • Cut two strips of double stick that are a hair less wide than the width of the stick.
  • Apply double stick paper onto both sides of the sanding stick.
  • Cut foam at double the width of stick plus, add a handful of millimeters extra.  You need to take into account the depth of the stick and add a little for the thickness of the foam.
  • Wrap foam around stick, having both edges meet in the center of the stick.
  • Apply another layer of double stick paper, only to the back of the foam stick (where the seam is).  Wrap sandpaper around the stick with edges meeting on the back side. Press down into double stick.

Sanding stick without foam

  • Cut and shape as in the instructions above.  Apply double stick to one side of the stick.  Apply the sanding paper and wrap around stick.  See images.

    Materials:  Double stick paper, sandpaper, craft stick & craft foam.

   Craft stick with end cut off and double stick applied.     Foam stuck to craft stick with double stick applied to the back, on top of the foam, to hold the sandpaper in place.

   Apply sandpaper to the back.

  The finished sanding stick.

  • You can also use rubber cement or other glue.
  • Stay away from Elmer-type glue  – too wet and too slow!
  • Another idea is to use an elastic band on each end or just use masking or painter’s tape.
  • You can also make a sanding block from wood or a foam core.

For interior spaces, you can use Mitchell’s abrasive cords or tapes. Tiny files, like micro needle files or escapement files will also help.

mitchell-sanding-tape-in-saw  I often put these 3m sanding bands into my jeweler’s saw frame to sand tight areas.  You can also put Mitchell’s cords and tape into your saw frame.

Creating Special Finishes

 Is It Ok To Rub A Green-Scrungy-Thingy On 14k Gold-Filled Sheet Metal To Get A Brushed Finish Or To Fine Steel Wool It?

Question

“Is it ok to rub a green-scrungy-thingy on 14k gold-filled sheet metal to get a brushed finish? Or to fine steel wool it? I live in the tropics and tarnish is an issue.”

Here’s a photo of what I’m trying to achieve: one is brass, the other is the gold-fill. I don’t want to sell anything that will tarnish easily, and I don’t want to use laqueur. I’m trying to get away from using brass, and this piece is popular, so I’d like to try gold-filled.”

Nancy

Answer

You can use the green scrubby thingy and steel wool (0000) on the metal – all of it.  Don’t rub too hard.  Hopefully, the gold filled is of good quality.  There is some crappy stuff out there.  See my page on gold filled for more information. The gold may tarnish a bit – not too much – not like silver, brass, bronze or copper.  It tarnishes because it has copper in it.  So, tarnish free may only be a dream…I don’t recommend sealers, like Protecta Clear – Everbrite, unless it is used on earrings or necklaces.  On other types of jewelry i.e.: rings and bracelets, the wear is too great.  Tarnish can be beautiful – learn to appreciate and stand behind it!

How to Create a Scratched (“Ice”) Finish on Gold and Silver

Question

How do you put an scratched (“ice”) finish on metal jewelry?”

ice goldice silver

Answer

There are many different types of tools that can give that scratched (or, as this company calls it:  Ice) finish.  Even something as simple as the edge of a square file can do it. Use the file like you would if you were shading with a pencil.  There are checkering files too that give a nice texture.

There are wheel brushes too like this cable twist wire wheel – wear gloves!  Not for the flex shaft. You could try a really rough mini-fiber wheel or a texture wheel (note:  the texture wheels are too large for a flex shaft and are best with a polishing motor.  Another option is a Mizzy Wheel.  You need a mandrel for them but, you can use them in the flex shaft.  You could also try a really rough sandpaper like 80 or 100 grit.

You could also use an angle grinder with a rough grit.

Sanding bands are another option.

George Goehl has a lot of information on Vimeo about finishing metal.  You might have to rent one for 3.00 but he presents some ideas in the trailer.  I know his youtube video talks about a lot of tools for texturing.  He is a sculptor but, the techniques will work for jewelers too.

The big rule here is:  test on sample metal first! Back to Table of Contents

Can I Silver Plate Nickel?

Question

“Is there a way to add a light coat of silver on top kind of like a plating?”

Answer

You can have it plated or learn to do it yourself.  I only use a plating pen and only infrequently.  There are places that you can send your work out to but, I don’t know of any offhand. Nickel can be plated. Back to Table of Contents

How Do I Texture My Metal To Match This Pattern (Looks Like Reticulation or A Sandpaper Finish)

Question

Rough-Finish-on-metal  “I’ve looked all over, and have yet to find an answer. And this may be out of your expertise  but I’m looking to find out how to make the finish seen here, on this ring by La Masters of Fine Jewelry.

Some call it a wire-brushed finish not to be confused with the common brushed finish.
I’m thinking it may be a specialty rolled impression. Have you seen it before and know how it’s done?”

It looks a bit like reticulation.  It could also be an impressed pattern.  I’d make a texture hammer, texture your metal and use the back side.  Maybe texture on wood so that the underside keeps it shape.  You could also try running a piece of 180 grit sandpaper in a rolling mill and using the back side.  Protect your mill by making either a thick paper sandwich (like watercolor paper) or brass sandwich around the metal and the sandpaper.
Chances are though, that it’s a machined finish that is proprietary.  But, you can experiment and find something close.
The finish is probably brushed – after the texturing is done.  Have you seen my Questions and Answers page: Finishing Questions? I also have another page on Finishing.  Here’s the link to the specific information that you need:  Brushed or Textured FinishBack to Table of Contents

How to Create a White, Matte or Satin (“Ice”) Finish on Silver

Question

“How do I create the finish below? Is it a chemical thing?”

Answer

Without actually seeing the jewelry – personally – I can only guess.  It looks like depletion gilding (some call it “Bright Dipping” where the fine silver is brought to the surface of silver.  The metal is heated, pickled, heated, pickled, etc.  up to 7-10 times.  The problem with this technique is that the layer of white, fine silver, is very thin and easily worn or scratched without some sort of protective coating.  It also could be a sandblasted finish and then depletion gilded. Maybe it is etched and then depletion gilded. Fine and sterling silvers, PMC or silver metal clay, will all have this white layer after firing or torching then pickling.

Sandblasting will also create this type of effect. Harbor Freight has a Portable Abrasive Blaster (Item # 37025) for $34.99.  BUT, you need a compressor too.  Harbor Freight carries small compressors.  Check to see what psi the blaster requires before purchasing a compressor.  I have never used this product.

You can also try Mizzi Wheels, Deburring Wheels, 3M Unitized Wheels, (item 330560 at Rio Grande) or a tumbling/polishing medium.  Some use steel wool or SOS Pads or something similar.  You can also use 3M’s Scotch-Brite Pads.
