Ceramic pans are similar to non stick pans, but with one crucial difference. Because part of the coating releases every time it heats up (that’s the “self-sacrificing” bit), ceramic pans become less non stick with every use, making for a pan with a shorter lifespan. On the plus side, ceramic pans’ aluminum core makes them relatively lightweight and easy to handle.
Because of this particular factor, the word skillet is almost always used to refer to cast iron skillets.
