Bake-o-Glide

Bake-o-Glide is the trade name for a PTFE-coated fabric that is often used as a non-stick baking sheet that cooking dignitary Nigella Lawson 'couldn’t live without'. PTFE (polytetrafluoroethylene) was discovered and developed by Dupont, whose trade name for it is Teflon®. It is a fluorocarbon plastic - a plastic where the hydrogen normally found in association with carbon in organic materials has been replaced by fluorine. This produces a number of remarkable properties; PTFE is reputedly the most inert substance known to man affected only by a number of uncommon substances at high temperatures, and is therefore suitable for food-contact. It is also very low-friction, non-stick and easy-clean. It is resistant to fungus, mildew, chemical corrosion and moisture, and because it resists extreme heat and cold it can be used in both the oven and freezer.
