Dear Tom from Element 79
I' ve been a goldsmith for close to 30 years now, and one of
my pet peeves, is the useage of hard and soft to describe metal.
I certainly do understand what you mean, but I completely disagree.
Firstly:The Oxford English Reference Dictionary says about hard, adj:
(of a substance, material etc.) firm and solid, unyielding to
pressure; not easily cut.
A softer material will scratch more readily than a harder material.
Nope, it all depends, but a harder material will scratch will scratch
a softer material, if we pseek about the Mohs scale of hardness.
The hardness of Quartz is 7.25. Nope, the hardness according to Mohs
is 7, as the Austrian mineralog defined the hardness of Quartz as 7.
And when you speek of hardness scales it is a good thing to mention
what scale you are referring to. Both Brinell and Vicker’s has been
established hardness scales in the metallurgic industry for more than
The more alloy that is added to a metal, like gold, the less dense it
becomes, the sooner it will ware out. Here I don’t agree. To my
experience high karat gold bracelets Wear out (I take it this is what
you mean) quite faster than low karats.
It’s My wish that goldsmiths or metalsmiths not get sucked into the
trap of describing metal as hard or soft, and work on educating
their customers to the beauty of high karat metal. Tom @ Element 79 As
you might understand, you have not convinced me, so I think I’ll
stick to the good old words, as I don’t want to start explaining to
my customers about Brinell vs. Mohs vs. Vicker’s vs. maleability and
