When I asked they told me it was 24 Kt. I didn't think jewelry could be done >higher than 22Kt.because it would be too soft. Along the same line, could one therefore melt and alloy a Maple Leaf instead >of buying pure gold grain?
Hi Linda,
As the Maple Leaf is finegold, there is no reason not to replace
grain with it, you could even roll it out and cut it with shears
to alloy parts of an ounce.
I’ve come across jewellery in 22kt quite often, as I do a lot of
repair work, it usually comes from the orient or near east
(Turkey, Arabia, Egypt). There is a manufacturer of chains in
24kt in Germany, I don’t know, however, how they make the
catches. A refiner here sells a 990/- gold (23.76kt) alloyed
with 1% titanium that he says has the same hardness as 18kt gold
when tempered (170HV).
BTW 1kt equals 41.666 thousandths, thus 14kt is 583/- (usually
585 is alloyed, except in Russia), 18kt is 750/-.
