I have a glass top electric stove (not induction) and I love cooking with clay pots on the stovetop. Several years doing this and I had my first pot crack on me last month (possibly from being dropped, possibly from being heated too quickly - I wasn't there so I don't know which). Would a heat defuser work on this kind of stove? Is it necessary as the glass does even out the heat fairly well?
Considering I cook with clay pots several times a week, and this is the first crack, maybe nothing needs changing. But I thought I would check just in case something can be improved.
If I need a heat defuser, what kind would work for my stove?
