I took Marcus Synot's course at the enamel conference in September 2011. I have fallen in love with his technique. I am using cloisonne wire for my skeleton and structure for the enamel. I never thought I could solder wire that small without melting it, but he taught us a trick.
We used a hard solder/flux mix in a plunger with a holder that made pressing the plunger "easy". Without the plunger all I wanted to do was cuss. Anyway, I have found a supplier. Stuller carries the holder with their own brand of solder.
I found it interesting using the hard solder as I have always used IT and I don't like using Eutectic (I don't know why, just don't)
I warm the area I need to solder, press the plunger and the solder comes out and spreads in the area I want it to go. When the metal is not warm, I get a "chunk" of solder and more than I wanted.
If you are unable to order from Stuller, just let me know and we can work something out.
