I'm a ceramic student who have chosen one of his favorite hobbies to make a project out of. Baking.
I've had enormous success with an old Römertopf I bought used, both for doing stews but especially baking.
The old Römertopf had some shortcomings though, it was really big, necessitating a rather large bread, or a half used space which is an energy waste I rarely tolerate.
I accidentally broke the lid by putting it on a wet tablecloth, thermal shock of the right kind will make it crack :s
