The big ones are the ones that do this the most, at least from what I've heard from potters. That's one reason why bonsai pots cost so much. Big pots go bad and have to be thrown out. I have a big Bryan Albright drum pot--almost 24 inches long that was custom made. He had to make it three times, as the first two cracked on bisque firing. The pot wound up costing him money to make for me, no profit.
