[teacherartexchange] Glaze Firing with Cracking

I just did a glaze firing and I experienced a tile project that cracked and
one that broke in half. I have the option on my kiln to do a fast glaze - 5
hours or a slow glaze cycle - about 7 hours. My thought is that the
fast glaze heated up to fast and caused the cracking. Does anyone have some
thoughts of why this happened?
