  1. Hello, My white gloss glaze has recently started pinholing I believe. We have been using it for years with no issue. i initially started with the kiln it is firing to temp. We fire slow bisque and slow glaze programs to 06 and 6. I have tried bisquing to 04 with a hold on the end but the defect came back... I have tried a hold on the end of a glaze firing (20 minutes) with little improvement. We have tried the ware with this glaze in 3 different kilns all have the same problem especially on larger ware. We have also tried wiping down the ware lightly with a sponge on both
