Hi! I am a newbie and could use some help. I made a 10" bowl with a sunflower by adding pre-fired petals, 1/4 " dots, and frit to one layer of Tekta clear. Everything went great making the blank, but after slumping I have several cracks running through parts of the bottom layer of Tekta. Here is the schedule I used:
300° 1000° 10
300 ° 1260° 10
9999 950° 45
125° 700° 0
What caused the cracks? How can I avoid this in the future?
Can I repair the cracks by heating it to a tack fuse in the mold?
