Cold enamel
A technique for decorating items that imitates true enamel on metal or porcelain
Cold enamel is a type of decorative coating that reproduces the effect of jewelry enamel but is applied without firing. The materials used are epoxy or acrylic resins mixed with coloring pigments. These resins are applied to metal, porcelain, glass, and after hardening produce a durable glossy surface. It looks striking on silver items — especially in the restoration of antique pieces where hot enamel is no longer possible.
The advantage of cold enamel: a wealth of colors, relative ease of application, resistance to abrasion. The disadvantage: cold enamel can be easily scratched by a sharp object. It is not as durable as classic fired enamel, but it often saves the day in cases where urgent restoration is needed, or the item cannot withstand high temperatures.
Sometimes collectors amusingly argue whether such a method deserves a place alongside the classics — auctions most often clearly mark the difference in the lot description.
