Clay cooking for a potter – thermal shock?

Do you realize that a pottery kiln is not the same thing as your household oven, don't you?

A kiln heats up very gradually, obtains a very high temperature, and cools down very gradually. Clay is very delicate and if the temperature changes are not slow, then it will break, crack, or even explode. You can not cook your pottery in a regular household oven.

Edit: Ok, the next time that you try to cook in one, you need to put it in a COLD oven, and gradually increase the heat to the desired temperature. When you take it out of the oven, keep it wrapped in a dish towel to avoid contact with the room air. It is the sudden change in temperatures that creates the fractures. The outside of the pot changes faster than the inside of the pot and the pottery cant expand or contract fast enough. I am going to guess that the one you originally used probably had hidden crack in it and EEWWW! I bet that was one ugly mess to clean up.

Oh no there's a trick to creating cookware from clay, no longer all clay may well be used and its maximum secure to apply a undeniable form of organic clay. the guy-made ceramic version has many ingredients which at the instant are not good for use for cooking i had a ceramic guru make some for me and it did no longer paintings, i eventually bought some from at Miriams Earthen Cookware, potters who concentrate on making clay cookware. that they had some beauties that worked somewhat properly, they get extra suitable and prepare dinner extra swifter as you utilize them.
