14 carat gold alloys


#1

Phillip,

In “Gold Alloys, Their Manufacture and Application”, by George E.
Gee, he gives the following 24 varieties of 14 Carat gold. The book
is dated 1929 and only has one alloy with any nickel in it.

Mr. Gee is also the author of: The Goldsmith’s Handbook The
Silversmith’s Handbook The Jeweller’s Assistant The Hall-Marking of
Jewellery Recovering Precious Metals from Waste Liquid Residues

When I learn to use my scanner I will post the accompanying text
page.

Dear Bill, I wonder how you can get .585 (14 k ) gold when alloying
with .583 gold ? Actually, considering when this was
printed , I think that it was within the law to underkarat gold
within a percent or so. Today anyone using the formulae that you have
posted might be skirting the industry standards, therefore, in order
to be usable for contemporary applications ,one had better make the
appropriate adjustments. Personally I prefer using the proprietary
alloys that are available from the major suppliers. These alloys have
been processed under controlled conditions and have been formulated
in accordance with state of the art metalurgical science. You pay a
bit more, but the results are predictable and pleasing. Ron at Mills
