Where does enamel iron come from?

Enamel iron typically comes from iron oxide pigments used in ceramic glazes and enamel coatings. These pigments are derived from naturally occurring minerals, such as hematite and magnetite, which are mined and processed to create the desired color and properties. The resulting enamel iron is then mixed with other materials to produce durable and colorful enamel finishes used in various applications, including cookware and artistic ceramics.
