Hi Antoinette -

A couple of things for you and/or your student to think about:   why bother....clay is a very poor conductor of heat;  high-fire, vitrified clays specially formulated for stovetop cooking usually include a lot of lithium compounds (e.g., spodumene) to allow for the thermal shock, but these formulations are difficult to fit glazes to;  if you/your student later assert that some ware is stove-top safe, there are liability issues attached if the pot later fails (check out this older thread:  http://www.potters.org/subject11478.htm)   Eric
