Hi together,
thanks for your replies!
Well I did not encase the trans. black ... I encased the clear with it.
Shawnette I think it was probably Vetrofond clear. Hmmm... must confess I'm not very sure, it also could be Moretti, but tend more to Vetrofond. If the cracks were there right after the kiln ...oh well... but after months??
I better use that glass only for spacers in future.
Working that glass cooler is only because of the bubbles and "scum", I don't think that it's got to do something with cracking.
OK, thank you all
