Hi George,

With regards to the density given for hard gold of 17.5 g/cc, what is the
degree of hardness, in Knoop, referenced, corresponding to cobalt or
nickel concentrations; does higher concentrations of cobalt or nickel vary
the deposit density for the same hardness value. And is the porosity of
immersion gold the same as electrolytic gold, and if it is different, would
that affect the density to any great extent.


Thanks,
