Sand mixed with bentonite, sculpted then dried in a kiln.

Stainless steel box filled with damp sand, that would ‘dug’ out, the half face fixed in place, dusted with graphite (release agent).

Hot glass, heated to 1100 degrees C, is gathered onto a blowing rod and poured like honey into the mould. The first layer has copper carbonate powder sieved over it (creating the bubbles) and than it’s capped with a second layer of glass. The whole ‘box’ is then placed in the kiln for four daysto cool down slowly. Once cooled, the piece is ground flat on three sides using different sizes of silicon carbide grit and finally polished.
