Cookware Glossary

Every technical term, pan form, material, and coating used across this site, defined once so pages can link together.

Forms

• Frying Pan / Skillet — A shallow, flat-bottomed pan with sloped sides, used for frying, searing, and sautéing.
• Pan (generic) — A catch-all form for material-defined pans whose exact shape (skillet vs saucepan) is not specified.
• Saucepan — A deep, straight-sided pot with a long handle and lid, used for simmering sauces and liquids.
• Sauté Pan — A wide pan with tall straight sides and a lid, giving more volume than a skillet for sautéing.
• Wok — A round- or flat-bottomed, high-sided pan for high-heat stir-frying.
• Dutch Oven — A heavy, thick-walled lidded pot (often enameled cast iron) for braising and stewing.
• Stockpot — A tall, large-capacity pot for boiling stock, pasta, and soups.
• Griddle / Grill Pan — A flat or ridged cooking surface for pancakes, grilling, and indoor griddling.
• Roasting Pan — A large rectangular pan for roasting meat and vegetables in the oven.
• Cookware Set — A bundled collection of multiple pots and pans sold together.
• Cookware Accessory — Supporting cookware items (lids, handles, racks, utensils) rather than cooking vessels.
• Lid / Replacement Part — Lids and replacement parts for cookware.
• Bakeware — Pans and dishes for baking (excluded from the cookware analysis scope).
• Pressure Cooker — A sealed pot that cooks under high-pressure steam (excluded from scope).
• Slow Cooker — An electric countertop pot for low-temperature, long-duration cooking (excluded).
• Rice Cooker — An electric appliance for cooking rice (excluded).
• Other Cookware — Long-tail cookware that does not fit the main form classes.

Materials

• Cast Iron — Iron with high carbon content; heavy and heat-retentive, and seasons into a natural nonstick surface.
• Enameled Cast Iron — Cast iron coated with a vitreous enamel layer; nonreactive and needs no seasoning.
• Stainless Steel — An iron-chromium alloy that is nonreactive and durable, but conducts heat poorly unless clad.
• Aluminum — A light metal with excellent heat conductivity; reactive to acids unless coated or anodized.
• Hard-Anodized Aluminum — Aluminum with an electrochemically hardened oxide surface; durable and nonreactive.
• Carbon Steel — Steel with higher carbon than stainless; lighter than cast iron, seasons to nonstick, tolerates high heat.
• Copper — An excellent heat conductor with responsive temperature control; reactive, so usually lined.
• Ceramic — An inorganic non-metallic solid; used as a ceramic nonstick coating or a glassy body.
• Stone — A stone-derived or stone-like composite, often a mineral-reinforced nonstick coating.
• Glass — A nonreactive transparent material for oven/baking vessels and lids.
• Titanium — A light, strong metal; in cookware it usually appears as a coating or reinforcement.
• Plastic — A polymer used for handles, lids, and accessories — not for cooking surfaces.
• Silicone — A heat-resistant flexible polymer used for utensils, gaskets, and handle grips.
• Nonstick (unknown base) — A nonstick surface whose base material is unspecified.
• Mixed — Products that combine multiple materials.
• Unknown — Material or coating not identified in the source data.

Coatings

• None (bare) — No coating — bare metal that may be seasoned to build a natural nonstick patina.
• PTFE Nonstick — A polytetrafluoroethylene (Teflon) nonstick coating.
• Ceramic Nonstick — A sol-gel silica-based nonstick coating, often marketed as ceramic nonstick.
• Enamel — A vitreous enamel (porcelain) coating, commonly applied to cast iron.
• Anodized — An electrochemical oxide coating applied to aluminum.
• Seasoned — A polymerized-oil patina built up through repeated seasoning of bare metal.
• Decorative Nonstick — Nonstick coatings marketed with decorative particles (marble, granite, diamond).
• Unknown — Material or coating not identified in the source data.

Concepts

• PTFE (Teflon) — Polytetrafluoroethylene, the inert fluoropolymer behind Teflon nonstick coatings.
• PFAS (Forever Chemicals) — A family of fluorinated compounds; some nonstick coatings historically used them.
• PFOA — A PFAS compound previously used in nonstick manufacturing; largely phased out.
• Maillard Reaction — The browning reaction between amino acids and sugars under heat; it creates crust and flavor.
• Leidenfrost Effect — A vapor layer that forms when liquid touches a surface above its boiling point; the basis of water-bead pan tests.
• Seasoning (Cookware) — Polymerized oil baked onto bare metal to build a nonstick, rust-resistant layer.
• Induction Cooking — Heating by magnetic field; it requires a ferromagnetic pan base.
• Thermal Mass — A material’s ability to store heat; higher thermal mass holds temperature better under load.
• Warping — Permanent deformation of a pan base, often caused by thermal shock or thin metal.
• Nonstick Surface — A surface property that reduces food adhesion, achieved by coating or seasoning.
• Dishwasher Safe — Able to withstand dishwasher detergent and heat without damage.
• Oven Safe — Able to withstand oven temperatures, often limited by handle or lid materials.
