I have 2 ceramic pieces that broke in a move.
One is an earthenware pot with a handle. It's that special ceramic from Europe that can also be used on the stove. The handle part broke off from the body of the pot. Yes, I can still use the body of the pot as a casserole but I like having the handle.
Item #2 is a ceramic bread warmer. This is is a round terracotta disc. You warm it in the oven and then put it in your bread basket under a napkin. It's got a crack right down the middle. This one doesn't technically touch food either.
Are there any epoxies strong enough to endure the high heat of a stove top/oven? I have already consulted the board and found this post: http://chowhound.chow.com/topics/302720
