Non-stick A process for bonding
Teflon to chemically roughened aluminium was patented in France by Marc Gregoire in 1954. In 1956 he formed a company to market
non-stick cookware under the "
Tefal" brand name. The durability of the early coatings was initially poor, but improvements in manufacturing have made these products a kitchen standard. The surface is not as tough as metal and the use of metal utensils (e.g.
spatulas) can permanently mar the coating and degrade its non-stick property. For some cooking preparations a non-stick frying pan is inappropriate, especially for
deglazing, where the residue of browning is to be incorporated in a later step such as a pan sauce. Since little to no residue can stick to the surface, the sauce will fail for lack of its primary flavouring agent.
Electric An electric frying pan or electric skillet incorporates an electric
heating element into the frying pan itself and so can function independently off of a
cooking stove. Accordingly, it has heat-insulated legs for standing on a countertop. (The legs usually attach to handles.) Electric frying pans are common in shapes that are unusual for 'unpowered' frying pans, notably square and rectangular. Most are designed with straighter sides than their stovetop cousins and include a lid. In this way they are a cross between a frying pan and a sauté pan. A modern electric skillet has an additional advantage over the stovetop version: heat regulation. The detachable power cord incorporates a thermostatic control for maintaining the desired temperature. With the perfection of the thermostatic control, the electric skillet became a popular kitchen appliance. In 1953, Sunbeam introduced the Automatic Frypan with built-in temperature controls, which helped the device gain widespread popularity. Although it largely has been supplanted by the
microwave oven, it is still in use in many kitchens.
Diamond Diamond frying pans are produced by bonding
diamond particles to a metal base, typically
carbon steel, through
vacuum-brazing under controlled conditions to prevent
oxidation and create a durable, scratch-resistant cooking surface. Diamond's high
thermal conductivity (900–2320 W/m·K) may offer rapid and even heat distribution, making them useful for high-temperature cooking methods like searing and stir-frying. Additionally, diamond surfaces are usually
hydrophobic, lending them
non-stick qualities; some manufacturers enhance these with
silicone resin fillers for better food release. Marketed as a
PFAS-free alternative to traditional non-stick coatings, their long-term durability remains to fully be established due to their relatively recent introduction to the market. == See also ==
