fonnage

Fonnage refers to the practice of applying a non-stick coating to cookware. This coating is typically a type of polytetrafluoroethylene (PTFE), a synthetic fluoropolymer of tetrafluoroethylene. The primary purpose of fonnage is to prevent food from adhering to the cooking surface, making cooking easier and cleanup simpler.

The most common type of fonnage is often referred to by the brand name Teflon. However, many manufacturers produce similar non-stick coatings using PTFE or other fluoropolymers. These coatings are applied in layers to the metal base of the cookware, such as aluminum or stainless steel. The cooking surface is then heated to cure the coating, creating a durable, non-stick layer.

Fonnage is applied to a wide variety of cookware, including frying pans, saucepans, baking sheets, and woks. Its effectiveness lies in its low coefficient of friction, which significantly reduces the adhesion of food molecules to the surface. This allows for cooking with less oil or fat, potentially contributing to healthier meal preparation.

While beneficial for cooking and cleaning, fonnage can degrade over time, especially with improper care. High heat, abrasive cleaning tools, and metal utensils can scratch or wear away the non-stick layer, reducing its effectiveness and potentially releasing small particles. Manufacturers typically provide guidelines for caring for fonnaged cookware to prolong its lifespan.
