Metal needs to be clean and there can't be any barriers (like oxidation) between it and the solder. Leaded paste is scary - don't use it. I'm not sure what temperatures that your butane torch will reach. Is it hot enough to melt the solder? Check with the manufacturer of both the solder and the torch. Be sure the torch reaches high enough temperatures to melt the solder. I discuss torches on my soldering page. How big is the piece? Large pieces take more heat to have the solder flow. Is the easy silver solder paste for soft soldering or hard soldering (also called brazing)? Are you using flux? Use the smallest amount of solder possible. When soldering, remember that solder flows towards the heat. heat both pieces, that are to be joined, evenly. When both pieces reach the correct temperature (the solder's flow point), the solder will "run" along the seam. So, for successful soldering, the most important elements are: clean metal, clean solder, FLUX , a good join (no gaps) between pieces to be soldered and enough heat. If you have all these ingredients then you should be able to solder. Good luck, let me know how it goes. Nancy Hi Maria, first off – oxidized brass won’t solder because of the oxidation.

I have used leaded paste or "solderit" (which dries out really fast) but the easy silver solder paste will not work using a small butane torch . Really don't know what type of torch to use.
