When I”m not making dichroic glass beads or cupcakes I find my self enthralled with reactive glass. Double Helix makes me crazy. Iris orange aka Raku glass makes me giggle with joy most of the time. And now Gaffer’s Blue Chalcedony takes me right between the two reactions just described. Gaffer Glass is COE 96 so it isn’t compatible with Moretti/Effetre or Double Helix and all the other 104 glass out there. But that’s OK, as long as you keep your glass properly segregated. The Blue Chalcedony is a blue version of Raku which means it’s a glass that starts one color and then upon heating and cooling and heating and allowing it to bloom all of these different colors appear, with a predominance of blues. So cool. It makes me swoon with delight. Now considering I’ve been making glass beads for over 16 years that’s saying something.
