In regards to induction hobs, it seems most, if not all of them, have glass tops. Why aren't they made of something more sturdy like ceramic or stone?

- barkbro 10y agoThere might be a good reason why they use glass ceramics instead of for example stone. Maybe because it's harder to manufacture consistently (ferromagnetic impurities?), has a larger coefficient of expansion or because it's harder to implement touch controls for them. It might just be more expensive.
