    Stainless steel foil is used in the heat treating industry. It is
    available in two types for this use. One is type 321 stainless steel
    and is the least expensive of the two it will work up to 1600 F which
    is above the laminating temperature for most jewelry metals. It comes
    in rols that are 12 or 24 " wide and of varying lengths(10, 25, 50,or
    100 ft). The second type is 309 stainless steel and is good to 2000F
    but quite a bit more expensive. It is quite a bit tougher than
    aluminum foil but you can cut it easily with scissors and it forms
    fairly easily by hand. Use a rawhide or rubber mallet to seal the
    folded edges. A word of warning about the stainless steel foil, it
    is.002 in thick and the edge is like a razor blade, think of paper
    cut on steroids. Always wear cut resistant gloves of leather or
    kevlar when handling the foil to avoid being badly cut. 

    To find it look for "tool wrap" at a machinery supplier like MSC,
    Enco, Travers etc all of which have online sales or my favorite
    McMaster-Carr at mcmaster.com
