I hold a MA in archaeology and am currently doing some preliminary research on 'white metals' for a project. I have found that the definition of 'white metal' differs depending on the source (i.e. manufacturers, craftsmen, material specialists, etc.). Many craftsmen suggest that a 'white metal' is a metal/alloy with a low melting point, silver in color. Some manufacturers include Pb among Sn, Sb, Zn, and Bi while others omit it. Some material specialists include Ni (even though it has a higher melting point). And still others have gone as far as including Au, Ag, and Pt in the definition. I would be very interested to hear how people on this listserv define this term. Additionally I would be interested in any references regarding white metal alloys. Chris Wilkins
