    I have never heard of anyone doing this. Fine gold melts at 1064.43
    C (1947.97 F) and would need to be at least 100 F hotter to not
    freeze the instant the object was put into the molten pool. Most
    easily worked metals melt below this temperature so it would only
    work on things like iron and nickel with very high melting temps
    they would have to be very clean and oxide free for the gold to bond
    to the surface.  I have heard of people referring to fire gilding as
    dipping the piece in molten gold but fire gilding is a amalgamation
    process where gold is mixed with mercury and the resulting paste is
    applied to an object and the mercury is then driven off by heat. 
    The gold coating is then burnished down to smooth and polish the
    surface.
