The coating on Anolon Vesta Cast Iron cookware is a glass or porcelain enamel coating. All cast iron cookware with a color exterior is coated with a glass or porcelain enamel coating. The material is sprayed on and then baked at over 2000 degrees Fahrenheit to melt and fuse to the cast iron pan body. We use a black ground coat on top of the iron and then a color layer goes over. The black enamel on the interior of the pan is a matte finish of porcelain enamel, and does not need to be as thick as the creamy colored exterior.
All enamel or porcelain enamel cast iron pans will still have exposed rims with no coating. These rims (or raw edges) can rust if exposed to water over time. If rust appears on the rim, rub some vegetable oil on the rim to remove and prevent further rusting. Wash and dry pans completely after each use. Always follow the use and care included with your product.
