New posting to The Gem and Jewelry Master Board BBS
I have been toying around with the idea of using Cobalt as an alloying
element in 22 K gold. Have been getting good results. The purpose was to
increase hardness !
I would like to know whether any veteran around has been trying the same thing
and has any interesting info in this regard been documented.
