Dori:

    I wouldn't recommend acetylene as a good gas for doing ANY work on
    silver: it combines chemically with silver when at high
    temperatures. This is the primary cause of fire scale in silver and
    its alloys. Also, you should add the precise amount of copper needed
    to make the 999 fine silver into sterling silver, as pure silver is
    just too soft to make jewelry. As for making it into sheet, a flat
    rolling mill will do what you need. If you don't have propane or
    natural gas or a rolling mill, take it to a jeweler who does and
    have them alloy, pour, and roll it into sheet.
