Re: Piece cracked on slump
Less heatwork, slower heating and longer annealing. Bullseye says three firings. Based on my experience with the early formulations of Bullseye where the COE could shift, my policy is to do no more than 2 firings. That requires rethinking what shapes you make, the molds you use and firing schedules. I can easily fire in a single long firing a 4 layer bowl that everyone else takes multiple firings to complete. That pattern you have could have been done in one firing.
