Any disasters? Techniques & tips?
I do a lot of torch fired enameling. I like the colors you can get with enamels, but a lot of the time I think of enamels as a patina. Not trying to get a solid even color, but a color mixed in with metal, leaving a more weathered, aged look. The benefit of using enamels in this way is that the look is relatively permanent. I don't need to seal it in any way.
Here is a pair of earring with patinized enamel on the top discs and a salt, lemon juice, and copper patina sealed with clear nail polish.
Sometimes I will seal my patinas with a carnuba wax, or hair spray (Aqua Net), or clear nail polish. A friend of mine just gave me a can of Nikolas spray lacquer, but I haven't tried it yet. She liked it a lot, said that it didn't affect the patina.
Other patinas I use are liver of sulphur, prismacolor pencils, sometimes LOS with prismacolor pencils.
