Abstract

Mercury gilding is a well-known decorative technique that was applied to both silver and a range of copper alloys from the third century AD until the introduction of electroplating in the nineteenth century. The process is well understood but, until recently, there has been no good archaeological evidence for it. Excavations in Southampton have discovered two rather different objects that were used to produce gold-mercury amalgam, the first stage in mercury gilding. One is a block of stone and the other a reused amphora sherd. The stone comes from a ninth-century context, while the amphora sherd's findspot is less well dated: it could have been reused in the late Roman or the Saxon period.
