Anotations

Scope note:

A semi-transparent or opaque vitreous, porcelain-like coating applied by fusion to metal, glass, or ceramic, having a glossy appearance after hardening. Enamel is typically made from powdered fusible glasses (e.g., quartz, feldspar, clay, soda, and borax) and opaque colorants (e.g., cobalt blue, tin oxide) mixed with oil or water, then painted or sprayed on the object and fired up to 800 C. Enamel is used to protect a surface, to decorate objects in various colors and patterns, to form a surface for encaustic painting, and for other purposes.
