How a nonstick coating fails
The slick film is thin and soft, and a cut or high heat breaks it.
When the purchase is complete, return to the original window. It will refresh.
From the opening
A nonstick coating fails when the thin slick film stops being a continuous skin between food and pan. Scratches cut that film, and enough heat can break the polymer, so food meets damaged coating or bare metal and sticks. The opening covers a thin fluoropolymer film, metal edges cut through it, and high heat breaks the polymer.
The rest of the brief — the later sections and the reading notes — opens after Stripe confirms payment.
