A vessel, typically used for serving liquids, fabricated by applying a layer of a precious metal to a base metal substrate is a common example of metalworking. This construction technique combines the aesthetic appeal and corrosion resistance of the exterior metal with the structural integrity and cost-effectiveness of the interior metal. A frequently encountered instance of this technique involves using a red-colored metal as the core and coating it with a lustrous, white-colored metal.
This manufacturing process offered a more affordable alternative to crafting the entire item from the more expensive metal. Historically, it allowed for the creation of ornate and decorative objects that would have been prohibitively expensive if made entirely of the pricier material. The underlying metal provided strength and form, while the outer layer provided a visually pleasing surface and a degree of protection against tarnish and wear. These items are often valued for their beauty and as artifacts of a particular eras design sensibilities.
