Clay cooking for a potter 鈥?thermal shock?

I saw a lot of articles about cooking in clay pots



My hobby is pottery so I wanted to make a few pieces to use myself.



I made a tagine and had it fired to cone 10 using the regular class clay that has a lot of recycled clay in the studio



Using a very low fame the pot popped into 4 big pieces and a few small fragments within 30 seconds



Next time I am thinking about using a heat diffuser and maybe a piece that was only low fired to cone 05



Requesting advice to try simple clay pot cooking for a potter.Clay cooking for a potter 鈥?thermal shock?
I think clay pots are often meant to be used in the oven, at least it would be easier on the pot than a flame? In an oven they would be heated much more evenly. Look up Romertopf cooking.



Generally if you have the option Raku clay will withstand thermal shock much better than other clay.



Though there probably was something else wrong, as it is perfectly possible to put boiling water into tea pots and tea cups made from a wide variety of clay. Wouldn't expect an air bubble in the clay as this would have resulted in it breaking during firing. If it is glazed on both sides, maybe water got into cracks of the glaze and the water couldn't escape fast enough? Or maybe there was a hairline crack you couldn't see? Or the piece was cooled too quickly in the firing leaving residual stresses? I would keep trying.
