Some two days ago somebody came to my tool room to test the hardness
of the Gold strip (thickness o.70 mm). Can anyone suggest me how can
I check the hardness. Though I do have Rockwell hardness tester, but
the indentation it made on the strip was more deep than the
thickness of the gold strip. I am a newbie in the jewelry field. And
also this is my first posting on Ganoksin.
So, I want to apologize if I am asking a rather simple question.
Please accept my thanks in advance, for the suggestion you provide.
In my day job I work at a machineshop working on automotive parts,
we have an electronic hardness tester which works basicly the same,
but has lots of hardness scales programmed in it. I would think maybe
the brinell scale would be more use with gold. Try asking at a local
engine reconditioners if they have a brinell hardness tester - I
think gold would never get hard enough to register on the rockwell
scale.
