This was the version – black outside, inside cobalt blue – which used to be made for professional cooks.

Enamelled pots and pans are basically steel utensils coated with silicate glass. The glass-hard surface of enamel is amazing: it is safe for use with food, tasteless, corrosion-resistant, scratch-resistant, heat-resistant, and easy to clean. We offer cooking utensils in a particular colour combination: black on the outside and cobalt blue on the inside. These were the colours once exclusively reserved for cookware and cooking utensils used by professional chefs.
