Wasser Black Flashed Colored

product description

Flash is a technique in which colored glass is fired onto the surface of another layer of glass. Wasser’s Flash glass uses a solid white base, with a black, red, orange, green or blue layer. This technique allows the user to sandblast or etch through the thin top glass layer and reveal the semi-transparent white glass underneath.
