Unique and Beautiful but Sensitive


This is a gorgeous cyan-blue which resembles the soft glass copper blue that's sorely missing from other manufacturers' boro palette. Sadly, that's probably for a reason: Get this too hot, and the color gradually fades away into a white semi-opaque mass of tiny bubbles. Even at lower temperatures, the color intensity definitely takes a hit if worked for a long time, with more of a baby blue result. Generally, if you treat this like a cadmium color you will get the best results.
<br>Finally, I don't know if this is just a problem with the rough underside of these bars interfering with glass adherence, but I've had several pieces with this color under deep clear encasement break. Not sure if it's a COE problem but something to keep in mind.
