What is Porcelain Enamel and How Does it Work?
Porcelain enamel is a type of coating made from a mixture of metal oxide, silicon dioxide, and other materials. It is applied to a metal surface, typically cast iron or steel, using a high-temperature firing process. This process creates a durable, non-porous, and glossy finish that is resistant to scratches and corrosion.
Porcelain enamel is often used in cookware, such as Dutch ovens and skillets, because it provides a non-stick surface that is easy to clean and maintain. It is also heat-resistant, making it ideal for high-heat cooking methods like searing and frying. Additionally, porcelain enamel is a healthy cooking option because it is free from toxic chemicals like PFOA and PTFE.
What is Teflon and How Does it Work?
Teflon is a type of non-stick coating made from a synthetic polymer called polytetrafluoroethylene (PTFE). It is applied to a metal surface using a chemical process that creates a thin, slippery layer. This layer prevents food from sticking to the surface, making cooking and cleaning easier.
Teflon is commonly used in non-stick cookware, such as frying pans and saucepans, because it provides a low-friction surface that is easy to clean and maintain. However, Teflon has some limitations, including a lower heat tolerance than porcelain enamel and a risk of chipping or flaking off over time. Additionally, Teflon has been linked to health concerns, including the release of toxic fumes when heated to high temperatures.
