Color on Metal

This page is intended to elaborate and expand on the techniques discussed in my video and to present a few of the other types of patinas available.  This is by no means a complete listing of patinas (after all, I don’t have THAT much time left on the planet!).

First off – the warnings!

Please be aware of the hazards inherent in the patinas that you are using.  Gloves, protective glasses and ventilation are important and necessary considerations when working with chemicals.  Also, be aware of the flammability of the product.  Have appropriate fire and safety equipment on hand.

Make sure that your finish is compatible with your sealant!

Patinas

Patina is defined as a layer of corrosion on copper or copper alloys. In the jewelry world, the term now loosely means: color on metal.  The patina can be applied by immersion, spraying, heat or hand application.  Patinas occur naturally as a result of the environment – it’s generally a corrosive process involving oxygen, water and carbon. The Chinese buried their work, left instructions where their descendants could find it and hoped for the best.  Now, it’s a bit easier and you don’t have to rely on your great grandchildren anymore!  Nice.

Look at the Statue of Liberty – that woman rocks her patina!   She’s made of copper and sports a verdigris patina.  It’s  crusty, almost as thick as the copper beneath (in spots) and protects the metal underneath. To copy this effect all you need are oxygen, copper and a huge chunk of time.  But, there are quicker and easier ways to obtain this look.

The Science Company has great recipes and information for the metal artist and their eternal search for the perfect patina.  Don’t miss this site!  Here’s the Science Company’s link to patina recipes for Brass, Bronze and Copper.

Cold Patinas

Cold Patinas are, as a general rule, opaque.  The application of these patinas involves applying the agent  onto room temperature (cold) metal (65° – 75°F).  No heat is involved. Most of the time, these patinas are applied in layers until YOU are happy ( :  with the color.  The patina chemicals can be applied with sponges, brushes or sprays.

The drawback to cold patinas is that they are relatively fragile and need to be protected – either structurally or with lacquers, varnishes or waxes.  Oil based lacquers and varnishes tend to hold the colors better. ProtectaClear by Everbrite is skin safe and is great on metal. I’ve put it through some rigorous tests and it didn’t chip or peel.  The colors stayed bright.  Waxes have different application methods – depending on the wax.  Hot waxes are applied with a brush to hot metal.  This technique can alter the patina dramatically.  Other waxes, like Renaissance wax (this place has good prices – but never ordered from them) are applied to room temperature metals. Every sealer, including Renaissance wax,  changes the appearance of the patina.  The idea is to experiment…

Here’s a patina I created, using       liver of sulfur and Jax’s Green Patina for copper, brass and bronze. Jax’s has tons of pre-mixed solutions for coloring metal. There’s a finish to replicate 24k on brass, brown, antique rust,  brown-black and more.  There’s also blackeners and darkeners for aluminum, steel, iron, nickel and pewter, as well as metal cleaners. They also have stains, waxes, lacquers and so much more. Here’s the MSDS on Jax’s green patina.

Another product is Baldwin’s Patina which doesn’t darken sterling, nickel silver, or gold alloys. It works with copper and steel clays as well as with  brass, bronze and copper metals. This fact makes it a cool product to use when you want to darken the copper based metals but not the silver or gold in a piece of jewelry. Apparently, Baldwin’s doesn’t color bronze or white-bronze clays – if they are sanded.  That information is from Hadar Jacobson’s video on YouTube – I haven’t experimented with it.  By the way, DON’T do what she is doing in the video:  dipping her ungloved hands into that stuff.  Made me shiver. Quote from the MSDA:

 "Prolonged skin contact may cause irritation, with inflammation, swelling, and edema.
skin disorders may be aggravated by exposure"

Here’s the MSDS on it.

Another great place to go for Patinas, besides Jax is Sculpt Nouveau.  They have tons of different materials to color ANYTHING (I think – well, maybe not amoebas).

I’ve made a separate page:  Sculpt Nouveau, for you to see the variety of patinas and metal finishes that they have available.

Rust on Steel

Want instant rust on steel? Mix up 4 parts white household vinegar to 1 part hydrogen peroxide (over the counter) and 1/2 part table salt. Put in a spritzer bottle and spray evenly. Before starting, ensure that your metal is very clean.  You can clean the steel by scrubbing it with TSP (Trisodium Phosphate).  Rinse and let dry.

Hot Patinas

Hot patinas involve, hold it…have you guessed yet?  Yep, heat. The metal is heated with a torch, oven, good looking guy,  heat gun, hot plate,  the sun (alternately the planet Mercury), or a kiln but, Not the Microwave!  The temperature of the metal should be about 200° F .  You can tell it’s hot enough if distilled water sizzles on it.  (Regular water has too many chemicals and minerals in it and those elements can dirty the metal.)  Most hot patinas are transparent. The benefits to using heat, besides the transparency thing,  is that the patina chemicals get sucked up by the metal – it’s more than a surface-only treatment. You can also use this technique with acrylic paint and a heat gun (not a hair dryer) .  Paint with thinned acrylic paint onto the clean, cool surface of the metal and hit it with the heat gun.  As it dries, the paint moves into the “pores” of the metal.

More precautions must be taken when working with hot patinas then with cold patinas. Since you are working with potentially flammable chemicals and HOT metal, the chance of fire goes up, as does the risk of toxic fumes.  Spend the money, save your home and life and get a fire extinguisher.  They are pretty cheap. Amazon has one for about $25.00. Hopefully, your home is worth more than that! If you don’t value your home think about your lungs and your soft, sensitive skin.  Be good to yourselves.

The Compleat Sculptor has some good info on metal prep, patination and other metal patina related information. So does one of my favorite sites: Ganoksin.

Here are a few artists who use heat and patinas:  Stephen YuskoCarol Warner.  Patrick Kipper has also got this patina thing down!  Check out this link at BrynMorgan.com (started by Tim McCreight) which illustrates beautifully the amazing colors you can obtain using heat, oil and various metals.

Heat Patinas

Heat-patinas3  Another method for coloring brass and copper is heat. Heat patinas are different from Hot Patinas in that they only use heat. Below are pretty colors on copper that I made for show and tell!

These patinas are different than those discussed above as they only involve heat.  Once again, they need to be protected and as soon as you apply a wax, lacquer or sealant of any sort, the color changes. Hmmm… the eternal dilemma.  Here’s a site that discusses heat patinas further: Brynmorgen.

So, to make a heat patina, get some copper, brass or bronze, a torch and start playing.  Heat the piece slowly – pull the torch off and watch what happens.  Don’t like it – drop it into the pickle and start again.  I’ve found that, if I heat the metal, just a bit, let it cool a few degrees and then go back in with the torch – the colors are better.  Once again, experiment…

Buried Patinas

These are essentially patinas that come about after metal is “buried” in a “soil” that has been saturated with a patina creating solution.  Some examples of the “soil” are:  cat litter, sand, sawdust, torn fabric, tobacco, sawdust, pine needles, coffee and cotton wool.  Pretty much any absorbent material should work.  As far as solutions are concerned, anything could work.  Successful patinas have been created with:  Ammonia, urine (ugh!), vinegar, old wine, funky milk, cupric nitrate, etc.  I’m thinking of trying spaghetti sauce and Caeser salad.  Find more information on buried patination at Brynmorgen.com.

The best part of creating patinas is the experimentation and the end result.  So, go ahead, find something unique, soak it with something weird and see what happens.

The book:  Japanese Patinas (Eitoku Sugimori, 2004. Japanese Patinas, Brynmorgen Press.) recommends grating daikon radish and laying the mash over the metal for about 20 minutes prior to patination.  Supposedly, the radish prevents unevenness in the patination and enhances the color.

Very generally, the process of buried patinas involves immersion in the medium, in a covered container (Tupperware springs to mind!) for 24-36 hours.  You can and SHOULD check on it once in a while.  You can turn it or toss it – hey, it’s an experiment!  If you are going to be investing a million hours in a piece, you might want to make samples first.  But, I know you, you want RESULTS, and you want them NOW!  I know I do.  Maybe a vacation is in order here.

Other Color on Metal – Paints, Inks, Pencil, etc.

paint-patinas  (The paint “patinas” in the image, are done with acrylic paint, a heat gun and a product called:  Kroma Crackle).  There are quite a few ways to color your metal from enameling to colored resins.  You can use alcohol inks, colored pencil, acrylic paint, nail polish, even water colors, to name a few.   The trick is to put a good tooth on the metal with a rough sandpaper (220 or 320 grit).  With water colors, you need to apply a layer of gesso or white acrylic paint first, let it dry and then apply the color.

Don’t forget to protect your finish with some type of sealant!

 Liver of Sulfur

I’m spending a lot of verbiage on this patina as it’s probably the most popular.

                                                

First off and most importantly, THIS STUFF STINKS!  Ever been to Yellowstone or into the center of an active volcano (really?)?  That’s what it smells like.  So, my thought is to use this in a ventilated area.  There’s a lot of information on the web that this product is extremely hazardous.  Please read this MSDS before using.  There are a few things to consider when reading the MSDS: first off – you’re not working in large quantities.  You’re not storing a silo full of the stuff.  You’re not shoveling liver of sulfur into cans all day.  You’re not working in a liver of sulfur coloring factory.   The amount of time and the quantity of this chemical you will be using is small and, when in liquid form, dilute.  That’s not to say that you should eat the stuff and snort it likes it’s 1984.  Common sense is the keyword here. (got sense? Should make a tee shirt that asks this!)  

 LOS on silver.     LOS on copper.

Don’t eat it – it will react with your stomach acids and cause hydrogen sulfide (which you may have been exposed to in that volcano) . Hydrogen sulfide is flammable and highly poisonous.  So, don’t mix sulfurated potash (Liver of Sulfur) with ANY acids.

Ventilate. Mixed liver of sulfur stinks so, why smell it and second, it’s not great to inhale chemicals whether toxic or not. The powder is an irritant to the upper respiratory system but, since it is in lump form, the chance of inhalation is limited. After you mix it up or if you are using the liquid or gel version – Go outside, open a door, turn on the kitchen hood, put a fan in the window with the air blowing out. Pick one.  You can choose all of the above options but you risk being accused of being obsessive or overly dramatic.  Applause anyone?

Glove up.  The powder and liquid can be a skin irritant.  Our skin likes to absorb stuff.  Do you want something that foul smelling IN your body?  Wear Gloves.

Some information for the test at the end of this page.  Flunk it and you’re grounded for a week!

Liver of sulfur is a combination of potassium sulfides.  It works, not by oxidation, (as it is commonly assumed) but, by a chemical reaction between the sulfur and the metal.  Liver of sulfur comes in a variety of forms including:  lump, liquid and gel.  The prior link is to Rio Grande Jewelry but,  Cool Tools  also has a version – the price is: 4ozs for $16.30.

Lump Form of LOS

The lump form has a long shelf life as long as it is kept in a dark place, not exposed to moisture and is stored in a relatively air tight container. (Sounds like my life). Liver chunklets come in big chunks (really? hmmm…) because it degrades from the outside in.  when you break open a lump, the interior will be darker and more potent.  Leave it in large lump form until you are ready to use it.  When it’s time to liver, break up one lump.  Spread out a bunch of newspaper on your desk,  Slip on your particulate mask, slather some masking tape over the end of your mallet (to keep the liver of sulfur out of it – especially if it’s a leather mallet). Slither into your gloves and, like the lady or gentleman that you are, gently tap the lump.  You want to see pea sized chunks. Not a pile of pulverized dust – remember that part about irritating your respiratory system?  Of course, you are wearing a mask, right?

Gel Form of LOS

The gel form, is easy to use and lasts longer. It’s syrupy and has to be mixed with water but, what’s one more task!  Rio Grande’s version of the gel is called  “Midas Liver of Sulfur“To have more control over the colors, it helps to have a more dilute solution.

Liquid Form of LOS

The liquid form is nothing more than pre-mixed LOS.  You can do the mixing yourself and save a lot of money. I don’t like the liquid form because: a. it costs a lot more and b. it doesn’t last very long. I had a bottle that only lasted a month or so.  I have a can of lump form that is over 8 years old.  So, comparing the two, I’d say: skip the liquid or buy the gel!

Rio Grande has a new product which looks very interesting but, isn’t.  Initially, I wrote Rio Grande about the product and they were going to test it and let me know the results but, the Tucson Gem Show was coming and….Alas, no information.  So, I bought the stuff.  It is a two part product, called: MIDAS Brilliance Gel,  that supposedly will cycle through all the colors that liver of sulfur (7) can produce and then will recycle back through them again but they will have a deeper hue and more iridescence.  Well, the instructions don’t clarify how to use it.  Are you supposed to dip it, or leave it in the solution?  So, I did both.  After an hour, the dipped silver was vaguely yellowish(?).  Nothing else happened.  Then I did the full immersion method and – nothing happened.  Finally, after four tries, I left it in the stuff overnight and I finally had pretty – pinks, golds, purples – colors but, the color spots were random and the rest of the piece was grayish. It seemed to me, to be very difficult to control, much less predict the length of exposure required for color.  To be fair,  I’m working in the dark – not having had instructions –  I’m not sure if I used the product correctly.  As of today, I don’t recommend it.

Liver of Sulfur on Brass

Liver of Sulfur is pretty iffy on brass.  If you like the look of age spots, go for it. It usually works best if there is a layer of copper flashing.   (Not this kind of copper flashing!) Copper flashing has two sources (that I know of).  One source of flashing occurs when Brass is heated past 850 degrees F.  In a process similar to depletion gilding, the zinc is depleted from the alloy (Brass is an alloy of zinc and copper) leaving a layer of copper.  Another method for creating copper flashing on brass is to add a piece of steel to a container with  jeweler’s pickle.  (Pickle is a dilute solution of acid or metal salts and is used to clean metal after soldering). Ever done this?  Put a piece in pickle That you didn’t know had a steel spring in the manufactured clasp?  Or forgotten to remove the binding wire? (Let’s hope you did that only once!) Well, congrats!  You’ve created copper flashing.  It’s a very thin layer of copper that is easy to remove BUT, can cause dangerous heart palpitations when you see it on your almost finished piece!

Removing Copper Flashing

To remove Copper Flashing and go on with your life, CAREFULLY, scoop a bit of pickle – about 1/8 cup – into a (dedicated for jewelry use) glass bowl.  Pour an equal amount of hydrogen peroxide (the stuff from the drugstore) into that bowl.  Drop in your piece.  In about a minute or less, the flashing will be gone.  Shazam!  The peroxide will dissipate in a few hours and you can pour the pickle back into the pot.

Using Liver of Sulfur

To get brilliant  controlled colors with LOS, try this method of application: You’ll need a way to heat water either in a crock pot (never again to be used for food!), on the stove or in the microwave.  If using a pot on the stove or tea kettle, pour the hot water into a LOS dedicated container.  Junk stores are a great source for cheap crock pots (crack pots?).  Don’t boil the water, just make it pretty hot. Ensure that there is enough water to cover the piece. You’ll also need two other dedicated containers: one to mix up the LOS in and one that will contain clear, clean water for rinsing. You will also need tweezers or tongs and gloves.  Ventilation too.

The Process

Using tweezers or tongs, drop the silver into the very hot water, wait until the metal heats up – a minute or so. With the tongs, pick up the hot silver and dip it into the LOS. Pull it out of the LOS after a second. Hold it there and watch as the colors change. If you love the colors, immediately rinse in the clear water. Not the colors you want? Repeat the process. Generally, the first dunking will result in yellow/gold. The second pinks/reds, the third turquoise/purples, the fourth moving into gray. After you are done with the colors, drop the piece into a container containing baking soda and water to help neutralize the LOS. Rinse again and seal. I’m liking a product called  Protectaclear from Everbrite for sealing but, you can use Renaissance wax or other products. The issue with the wax though is that the colors are altered by the product. I haven’t seen much color change with the Everbrite product.

Neutralizing Liver of Sulfur

Speaking of neutralizing:  you MUST, that’s MUST, neutralize liver of sulfur or it will continue to work.  Unsupervised LOS can be dangerous to your art!  The liver can continue to color your work. The best way to neutralize it is to plop it into a bowl of water and baking soda.  If you have colored a piece of metal clay, boiling it in baking soda is best.  Rinse well after the soda bath and clean with soap, warm water and a soft brush.  Don’t forget to kiss your piece and speak tenderly to it before sending it out into the world, alone and frightened. Boy, are you mean!

Disposing of liver of sulfur

Remember that part about LOS degrading when exposed to light and air.  Well, the nice or horrible thing about liver of sulfur is, that is becomes inert, inactive and pretty sad within a day.  You can stick it in a glass jar and wait it out, pour it down the sink and rinse or you can neutralize it, while still fresh, with baking soda, pour it down the sink and rinse.  It will not harm the water system if neutralized. You could call the USPHMSA (U.S. Department of  Transportation, Pipeline and Hazardous Materials Safety Administration) to dispose of it but, then they’d have you on their list. (All other countries, please search for the appropriate government agency to irritate).

Warning:  If you leave your piece in liver of sulfur too long, you will end up with a very dark, flaky crust of gray/black.  It’s almost sooty and will come off on whatever it touches.  Who knows, this might make your heart sing, not mine though!

Patinas on Gold

Gold does not oxidize or corrode like other metals.  Gold, silver, platinum, rhodium, (among others) are all considered “Noble Metals” because of this fact.  So, obtaining an aged look on gold can be a bear.  Charles Lewton-Brain talks about a a great way to obtain a LOS patina on gold:

“Liver of Sulfur does not take well on brass. Repeated heating and pickling or the introduction of iron to a pickle solution will coat the piece with copper which can be darkened. This is good for emphasizing recesses. 

This same idea is sometimes used on gold jewelry that has to be ‘antiqued’. Because gold alloys do not react to most sulfur solutions one can take some used pickle solution, place it into a bowl with the object and (wearing gloves) blot the object with some medium steel wool. This will contact plate the object and its recesses with copper. Then rinse, use the liver of sulfur solution to darken the plating to the desired level and buff off the surface with a rouge buff. The darkened recesses will be untouched by the buffing and so remain, everywhere else is bright.”

So, you are applying a copper flashing, coloring that and removing the areas, via polishing or sanding,  that you don’t want the flashing on – revealing the gold underneath.  Clever!

You can also use Gilder’s Paste and a sealer. Guilder’s Paste is pretty similar to shoe polish – which might work too!  Try it – if you dare! The Gilder’s Paste is waxed based so, shouldn’t be applied without some form of protection – like a sealer.  Here’s a video by Beadaholique that shows how to use the paste.

Sealing Patinas

This is always fun!  As soon as you apply anything, to your patina, the color changes.  That’s because, the coatings change the way light travels to our eyes.  So waxes, spray fixatives, dips and all other types of sealants, will alter the color/tone/reflective quality of your surface treatment. Some work better than others – experiment!

Knowing this, there are options to preserve a lot of the color and to protect the finish.

Some patinas should be protected  mechanically.  If your patina is very flaky or fragile, think about treating it like a gemstone and setting it.  Recessing the item also helps but, if you can’t or don’t want to do that, here are some solutions.

Note:  Not all products will work on all patinas or metal colorants so, test before you apply to your final work.

xilia-cuff-patina  (Xilia’s cuff with patina).  My FB friend, Xilia Mairead Faye (stupid WordPress – this link works even though it’s lined through!), has been playing with lots of different patinas and experimenting with sealants.  This is what she has discovered:

“I’ve been finding the Minwax water-based polyurethane has been working really awesomely, actually. I do 4 to 6 coats of that and then finish with Renaissance wax.  Someone I know,  has had his work last 10 years – even swimming in water regularly. He uses it on his fishing lures!…You can leave your work shiny or use the Renaissance wax to take some of the sheen off….NOTE: Only use the water-based sealer.  There is less smell and the oil based doesn’t dry clear and it also yellows!”

 

minwax   Xilia uses Minwax’s water-based,  polycrylic, clear spray.  Here’s a link for the satin finish, this is the link for semi-gloss and this is the link to the gloss.
Finishing.com, EverBrite and Sculpt Nouveau have tons of information on their sites.  Spend a few hours there and learn a lot!  Below, are a few examples:

Most finishes will need to be sealed and protected with a varnish – either water or oil based.  Another method for protecting the metal is to bezel set or tab set the piece – like you would a cabochon.  See my video:  Stone Setting:  Creating a Frame Setting for Cabochons (two parts) for one method of protecting a colored element.

Books on Patinas

Patinas are anything but reliable.  But, that makes the process all the more interesting. It is a journey, an experience and something worth investing our precious time in.   Below are three books that I own and recommend on surface coloration: (all book links are to Amazon).

  1. Hi Izzy, I think that you are leaving the piece in the liver of sulfer too long. That flaky crust thing only happens when you do. Are you trying to obtain a black surface? LOS doesn’t fade – at least the black doesn’t. The colors eventually fall victim to tarnish and fade, though. What are you sealing it with? Is the color fading after you apply the sealer? Let me know the particulars and we can procede from there. A photo would help too. If you want, email me at nancy.lt.hamilton@gmail.com. Thanks for visiting and writing. Take care. Nancy

  2. A big hug and a kiss to you Mia! Thank you so much for the wonderful comment. Where do I find the time? I don’t know – maybe giving up sleep and cooking? Crazy should be my new middle initial. Thanks and take care. Nancy

  3. Hi,

    I keep finding los patina flakes off as I’m trying to seal it. I get that it would fade over time but straight away? Any ideas how to prevent this?

    Thanks

  4. Darling Nancy
    your info is FAB!!! thanQ thanQ thanQ for putting out info that is accessible & easy to understand & free
    WHERE DO YOU FIND THE TIME GIRL??!!!!!
    I love watching your vids on you tube aswell xoxo
    love to you & BIG thanx & well wishes xoxoxoxo

  5. Hi Dean, First off Thanks! So, my first reaction to the idea of using LOS with food was: no way! But, the more I thought about it, I realized that it was not the LOS in question, but the actual silver sulfides that form as a result of the LOS – or other, naturally occurring tarnishing agents. Saying that, I found an alternative method that you might try. Check out Pearl’s blog: The Beading Gem’s Journal and her article: Tips on How to Use Boiled Eggs for Metal Oxidation (http://www.beadinggem.com/2011/06/tips-on-how-to-use-boiled-eggs-for.html). The other option you have is just waiting and let it patinate naturally. Onions also might work. Here’s an article titled: Exposure-Related Health Effects of Silver and Silver Compounds: A Review.(http://annhyg.oxfordjournals.org/content/49/7/575.full), that you might want to peruse. Here’s the MSDS on Silver Sulfide – (http://www.sciencelab.com/msds.php?msdsId=9927585). Make sure that it is well cleaned before use. I checked a bunch of other sites and no one seemed overly concerned to be eating off of tarnished silver. Although, after reading the above, I’d be nervous. I must say though, that a lot of these exposure-related health effects are based on greater concentrations of the chemical. One other note, certain foods may strip the patina off the metal – so keep that in mind. Good luck and thanks for the comment! Take care, Nancy

  6. Nancy,
    Hi. Such an informative website! I was planning on using LOS to darken silverplate flatware stamped with messages. I would then polish off most of the oxidation with a polish pad so that only the letters are dark. I was curious if you know if the this product would be safe to eat with? With my deductive reasoning i would think so. I know LOS is harmful to ingest however after polishing and cleaning I would think that only aluminum oxide is left and it would be safe as long as the spoons and forks are thoroughly cleaned. I’d love to hear your thoughts on this.

  7. Lala. I don’t know if you found a solution yet, but I wouldn’t paint something over the wax. I’d embed it INSIDE the wax. You could try melting some wax in a small container and mixing in some mica powder in whatever metallic color you want and then pour the wax into one of those ice trays that are made for making ice cubes that fit into water bottles. You could even push a wick down along the center of it, I bet! Another way would be to buy dark metallic hot glue sticks and just pool the glue like you would wax.

  8. Hi Lala, I don’t know of any product that will adhere to wax. Perhaps an Encaustic web site like this, Encaustic.com, will be able to help you. You can also contact the people at Sculpt Nouveau (sculptnouveau.com) for additional ideas. I’d probably make the seals out of polymer clay and use paint and patina solutions to achieve the look. Sorry I can’t help more, it’s just not my area of expertise. Good luck, I hope you figure something out. Take care, Nancy

  9. Hi,
    I am looking to make wax seals with a patina finish and was wondering if you have any tips on how to go about making them. Thanks.

  10. im wondering what i can put on religiuos metals to make them look rusty, They are just silver cheap metals they are not steel i do know that.

  11. Hi Sherry, Well, you just asked a tough question that has few answers. To date, I have found NOTHING that will seal and not flake/yellow/wear off of metal jewelry. The coating can last for a very long time in protected areas. But, in areas of heavy wear, like a ring band, the material wears/chips. Saying that, there are a few options:

    Everbrite is purportedly safe for jewelry use and long lasting. The people there were lovely and very helpful. I have not used this product but, would imagine that any application of a sealer will alter the colors of a patina somewhat. So, do a test piece.

    You could try a wax based product like Renaissance wax which is obviously, wax based. It will darken and (usually) dulls the bright colors of LOS. But, it can reduce the amount of tarnishing. It is not as long lasting (in exposed areas) as a sealant. Check out this ( http://ganoksin.com/blog/delpfinewelchdesigns/2008/10/12/sealing-patinas-brass-and-copper-with-wax/) page for more info on sealers. Notice that the area she is waxing is protected – this will cut down on flaking/chipping.

    What I generally do is: nothing. I just let the patina happen and swipe the metal with a polishing cloth when it gets dull. Occasionally, when I have a protected area I will apply a sealer. I’m going to purchase some Everbrite to test.

    So, sorry I couldn’t give you a better answer. This is a subject for ongoing research. If you discover any fabulous product, please let me know. Thanks, good luck and take care. Nancy

  12. Hello,
    I’m using liver of sulfur on copper and jewelry shield to seal it. However, when the jewelry shield comes off, it causes the liver of sulfur to come off too. Can you advise what I need to do the make this not happen or something other than jewelry shield that I can use to protect the finish and my customer’s?
    Thanks!
    Sherry

  13. Hi Nancy,
    So what was the low-down on the Midas gel? I’ve had it on my wishlist for a while & almost picked it up today, but Rio was OOS on the other item I wanted so it’s back on the shelf til October.

  14. Hi Jules, Sculpt Nouveau has one called Vista Blue that makes a turquoise color on brass, bronze and copper. There’s also one called Tiffany Green. They also have 3 blue patinas that they call Traditional Blue, that might work for you. I hope this helps. They are a great company to work with and will send you more information, if you’d like it. Take Care. Nancy

  15. Brass has become very popular now, what would you suggest using (or a method) on brass to get a great green/turquoise color patina?
