What Temperature Can Nonstick Coatings Actually Take?
PTFE coatings are generally rated to about 500F continuous use; ceramic often 550F or more. Follow the specific product rating.
The two common nonstick coating types have different manufacturer-stated maximum temperatures: PTFE (Teflon-style) coatings are generally rated for continuous use up to about 500°F, with brief exposure tolerance a bit higher, and coating breakdown becoming a manufacturer concern above that range. Ceramic (sol-gel) coatings are generally rated for higher continuous-use temperatures, with some formulations rated to 550°F or more. Always follow the specific manufacturer's stated maximum for your exact cookware rather than assuming one coating type's rating applies to all products using that coating family.
