Went to a local gem show on Saturday. Interesting display for faceting glass. The person uses insulator glass to make faceted glass. The insulators here are a CD 102 BTC of Can in purple, a CD 106 Hemingray in aqua and a CD 164 Dominion in straw. The dome piece in purple is interesting.A CD 102 No Name Canada [010] with backwards 2 on dome. Great use for an insulator
