Bullseye Sheet Glass: 3mm Dense White Opal 0313.30

Really disappointed with this - major de-vit problems which I've never experienced with any other colour. Excellent advice from the Warm Glass team, but a week of trying and test firings and I still have the same problem. opaque white gives good colour with no problems.

BULLSEYE GLASS CO. RESPONSE:
All of the 000313 Dense White sheet glass stocked by Warm Glass UK is tested compatible and suitable for most kilnforming applications.
With proper cleaning and under normal firing conditions in which contaminants are not introduced, all Bullseye glasses should fire cleanly.....
