Hi Everyone, I just cast my first wax piece with stones in place -
there are 6 little cz stone flush / burnish set into the surface. It
came out almost perfect, however, one of the stones is plated with
silver. I imagine there was an air bubble or something over the
outside of the stone leading to the thin layer of silver coating it.
Anything I can do to remove the silver? Someone suggested coating
most of the ring with nail polish and using nitric acid to dissolve
off the silver but this sounds a little scary to me. I am more
comfortable trying to polish it off using flex shaft and silicon
wheels. Any suggestions?
