Wissmach Black Opal Luminescent Fusible Glass 96 COE.
The coating on Wissmach Luminescent glass is similar to iridized coatings, however it reacts completely differently when fired. It's ideal for reverse fusing projects, where the front of your piece is face down on the kiln shelf and you build backwards. This allows you to create in a whole new way, and your art will look its best from both sides!
Quality, affordable, easy to cut glass.
