Hi everybody.
I would appreciate any help and comments to the following problem I face. I fire 2 layers of 3mm float coloured with 1045 Optul glass (cherry red – Lead free powdered glass) and bronze inclusion. The glass is not coloured throughout. I have fired this same small dish for approx. 4 years without a problem and with excellent results. During the past few months, air is trapped within the glass where there is no powder or inclusion and it becomes foggy. I tried to include a bubble squeeze to eliminate air trapped in the glass. Less air was trapped but the fog was still there. Anybody has any clue to how I can fix this?
