Copper clay pieces after firing, brass brushed. The round pieces are hollow forms, not solid.
PMC3 smeared into recessed areas. 2 pieces are sanded down to show the copper surface.
Finished earrings. PMC3 has been torch fired. Some shrinkage. Have not yet tried filling the cracks and refiring. Maybe I don’t mind the slight openings between some of the silver and copper. It would be good to know what happens if I were to fill in and refire….
Soldering sterling silver posts on copper clay. Hmmmm…. The one on the left worked well the first time. The one on the right took three tries and a lot of solder. Soldering on copper clay feels very similar to soldering on PMC original. The fired clay is still quite porous. I tried burnishing the area where I was going to put the post. Still tricky soldering. Has anyone else had trouble with this?
The hole that is distant from the post is a vent hole in the hollow form. The hole right next to the post is where the copper started to pit when I tried to solder.
