In this video, Pam East shows how to mask a texture so that you can use just the design you want and create a flat area before impressing into metal clay. The piece is fired, and the once masked area of the piece is then used to apply gold foil. Pam uses the Ultralite kiln for the keum-boo process.
Note: For keum-boo with the Ultralite, you need the brass covers which are sold separately.
