In compliance with British law, the British fine art trade uses the term "white metal" in auction catalogues to describe foreign silver items which do not carry British Assay Office marks, but which are nonetheless understood to be silver and are priced accordingly. Tin-lead and tin-copper alloys such as Babbitt metal have a low melting point that is ideal for use as solder, but these alloys also have ideal
