littonwarw 380 simmer pot

Toast

just bought this at good will can it be used to bake sourdough bread in

 if so how ?

those are not made of metal.  And while you can probably put them in the oven to 400 dF I wouldn't.  Pretty sure I had a piece of Littonware and it was like melamine.  I think it will melt at high temperatures needed for bread baking.

this is made of clay ( terracotta I think) , you need to soak it in water before using and put in a cold oven

Since it is made of clay, I would think it would work. Interesting, though, according to the documentation for the pot that you can see here... the pot was designed to work in the microwave oven. I don't know how that would translate to a regular oven. 

I have a Henry Watson Terracotta Clay Baking Brick ( called that , on the lid ) I bought it on eBay .I put my Pain au Levain in it for for the final fermentation, soaked the lid in HOT water , slashed the bread and put on the lid. Not knowing what would happen I put it into a pre heated 450 degree oven . I lowered the temperature to 440 as per Hamelman's instructions and waited for the worst to happen ! I removed the lid after 15 minutes and baked the best bread ever ! The pot did not break or even crack ! Next time I will put an oval piece of parchment paper in the base as the bread did stick . I would think that your terracotta pot would be fine - after all, as a friend reminded me, these pots are fired at higher temperatures than we bake with ! 

Good luck , Merlie.
