    The blue is from a trace amount of cobalt in the alloy. Currently 4
    alloys have risen to the top for casting. Johnson Matthey, Hoover
    and Strong, David Fell, and United Precious Metals. All 4 alloys have
    slightly different formulas and characteristics ranging from
    hardness to reusability. These slight formula changes do affect
    color. Side by side one can see the color variations making sizing
    and duplication cumbersome. Your caster or supplier should give you
    the contents of the alloy they are using or the main ingredients so
    that the pieces can be matched or sized. Feel free to call for any
    more detailed info.
