Are Teflon pots safe?
Also known as polytertrafluoroethylene (PTFE), this clear plastic is used to coat metal pots and pans, giving them a waxy, easy-to-clean surface — and for decades, scientists have debated whether it's safe for cooking. Experts tend to agree that Teflon itself isn't a problem. The coating itself is considered non-toxic.
Are all nonstick pans Teflon?
The best nonstick pans without Teflon boast similar stick-proof qualities, but they're often coated with a silica-based material (commonly referred to as ceramic) instead of polytetrafluoroethylene (PTFE). In addition to a ceramic pan, you might consider a well-seasoned cast iron one for cooking without Teflon.

How does Teflon work?
A manufacturer will etch tiny abrasions in the surface of a pan by sandblasting or applying chemicals. Teflon is then baked into the cracks. If you can imagine each small abrasion as a tiny dovetail joint, it’s easy to understand why the Teflon doesn’t simply slide free.
What is PTFE arranged in?
In layman’s terms, that means there is carbon at the center of every molecule AND the molecules are arranged in a large repeating pattern. The structure of these molecules is what makes PTFE uniquely slippery [5]. As shown above, PTFE is basically a long chain of Carbon atoms that is surrounded by Fluorine.
