The term identifies a specific type of tableware and decorative object coating. These items are generally composed of a base metal, such as brass or copper, that has been electrolytically coated with a layer of refined material. For example, a serving dish marked with the designation indicates it is not solid refined material, but rather plated with it.
The application of this coating provides several advantages. It offers a more affordable alternative to solid refined material objects, while still imparting a similar aesthetic appeal and tarnish resistance. Historically, this process enabled wider accessibility to elegantly styled dining and household items, reflecting a desired level of refinement without the associated high cost. The durability of the coating, while dependent on the thickness and quality of the plating process, generally allows for extended use with proper care and maintenance.
