Partial Plating by
Don Wagner
I have been trying to talk a friend into doing a partial plating job for me.
He refuses, saying that the masking material contaminates his plating

Mercury Amalgam Gilding by
Don Wagner
Another little project that I always wanted to pursue. I had an old "how
to" formula book that said to make a mercury copper amalgam, spatula it over
holes in old copper cookware, and then just let it set up overnight to
effect a permanent repair. It seemed absurdly simple.
Would it be possible...

What would happend... by
m4816k
....if I would take my 14K gold jewellery, together with my 24K gold coins to
jewellers, and say that I'd like him to mix those two to make a single piece
of jewellery? Mathematically, from mixing 14 and 24K in the right ratio, you
can (for example) get 18K gold. But, how smart is to ask jeweller...

On one site on the net, I've found informations about hardness of metals.
And it says that 14 K gold is about 2,5 times harder than sterling silver.
Does that mean that a 14 K gold, 5 gram chain has the same hardness
(strenght), as 12-13 gram sterling silver one, of the same design and...
