I've been having problems with fiber paper while fusing jewellery pieces.
I cannot understand what could be the reason it's happening.
I am fusing either on a ceramic bisque tile or a normal kiln shelf with thinfire on top, it happens on both shelves.
It happens on nearly every Bullseye colour I try to use, but not every firing even if the temperature is the same.
I was thinking maybe the temp is too high with all the tiles in the kiln, maybe that's the problem.
