About 1/4 inch thick. I believe thick is harder to crack. I've always cooled the kiln down for 24 or more hours before opening which means the temperature was under 130 degrees. Never open the kiln if it is hotter than that. I've only had one bowl crack and suspected it was because the glaze was too thick. We bought a Bowana bowl with a cracked inside and it looked like the glaze was thick. I re-fired it today with even more glaze to see if I could get it to heal. I'll let you know how that turns out. I've got my fingers cross for your barrels which are wonderful. Wendy
