Enamel ware is the process of coating a metal, such as steel or aluminum, with an enamel coating. This type of process is commonly used for cookware, as it preserves the metal underneath, which adds durability and longevity. Enamel ware is stain resistant, and the coating can be subjected to extremely high temperatures without cracking. Made of rock agate or granite particles that cover metal, cutting a hole requires two separate steps to get the job done correctly.
