Heat, ovens and cooktops
Every pan has an oven limit set by its weakest part: the knob, the handle, the lid or the coating. And not every pan works on every cooktop: induction needs a magnetic base.
- Oven limit
- the lowest-rated part sets it
- Induction
- a magnet must stick to the base
A pan's metal body usually tolerates far more heat than a home oven makes. The limit comes from the parts: a plastic or phenolic knob, a coated handle, a glass lid or a nonstick coating. The oven-safe checker finds the limiting part for a pan.
Induction heats the pan itself through a magnetic field, so the base must be magnetic. Cast iron, carbon steel and most clad stainless work; aluminum, copper and glass do not unless they have a steel plate. Hold a magnet to the base to check.
Glass and ceramic tops scratch if heavy pans are slid across them. Lift cast iron rather than dragging it, and keep the base clean and flat.
Common mistakes
- Putting a pan with a plastic knob in a hot oven for bread.
- Assuming a stainless pan is induction ready without testing with a magnet.
- Sliding a cast iron pot across a glass cooktop.
