I am making a set of 8 inch plates for a customer, using the 8 inch swoop mold. I used kiln wash on the mold, and also covered it with fusing paper, and I just checked it and found in cracked in half. I use a JenKen Bonny Glo kiln and follow their program instructions in most every piece I do, tweaking some programs as necessary. This piece was initially tack fused and had no cracks when I finished that procedure. Any assistance as to what caused the problem and how I can remedy it occuring again will be appreciated. Please email any responses to email@example.com.
