Each item features a hand-finished baked stainless steel trim creating a bronze-like patina finish, resulting in unique pieces that form a cohesive set. Our Enamelware rim is heat treated to create a bronze-like patina finish. Both the surface and rim can be stripped of its unique coloring by acidic foods, such as lemon, and some harsh detergents and cleansers. We recommend hand-washing to help maintain the original look and feel of the pieces. To hand wash: Use a gentle, natural cleanser. Soak the products in warm, soapy water to help remove baked-on food. Gently wipe away residue. Towel dry to avoid rusting. Avoid using abrasive sponges or brushes as this may scratch the surface. Hand-wash only (not recommended for dishwasher). Do not microwave.
