The first thing item on the agenda when purchasing a frypan is what size you should be looking for. Frypans generally range from 20cm up to 32cm in diameter. While 24cm is the most commonly purchased option, each option offers advantages based on your needs. As a general guide:
Copper is a great heat conductor, so copper frying pans heat up pretty quickly, but they lose heat just as fast. This prevents food from continuing to heat and burning up even after removing the source of heat. They're the exact opposite of cast iron. They're also not as resistant to high temperatures as cast iron and stainless steel. Anything above 450 degrees is a no-no.
