Ceramic cookware has been growing in popularity recently because of how effective it is. Much like a non-stick surface, ceramic is pretty useful to use for cooking because most things don’t stick to it, but unlike the non-stick technology that is also popular, ceramic can be used in microwave, oven or on the stove, so its versatility is a definite plus.
You often hear of ceramic cookware being advertised as a “multi-purpose” cooking pot, as it can be used to fit to your purpose, whatever it is, meanwhile a metal frying pan with a plastic handle is really only fit for the purpose of frying food.
There can also be some concern about the solution added to metal cooking surfaces in order to make it non-stick. As that layer does disappear over time, some of it can enter your food, which can be worrying. With a ceramic covering you don’t have to worry about this, but you should still avoid using metal on them as that may scratch it.
