The inner surfaces of cooking utensils, especially those used in the preparation of certain foods such as baked goods, desserts and cakes. And other foods that can stick to food, enamel coating and anodizing coating were made with thick layers of non-stick coatings, which were of a lower degree than the quality of Tefal in resisting food sticking, then non-stick coatings developed and what is known as ceramic coating appeared, especially applied in a way. Sol-Gel, which is considered an advanced non-stick coating, is suitable for most of the raw materials of cookware for preparing different types of food. The multiplicity of non-stick coating layers leads to an essential need to direct the user to choose the best non-stick layers that are safe to perform their functions.
