Hi, all-

What text(s) would you recommend for on gold alloys,
their composition and properties? I am looking for something beyond
that which can be found in Jewelry Concepts and Technology.

The most in one place is probably “Precious Metals Science and
Technology” from the International Precius Metal Institute 4905
Tilghman St. Allentown PA 18104. about $160 Translated from
Japanese.

Also"The Theory and Practice of Goldsmithing"by E Brepohl –
Translated from German be Charles Lewton-Brain

May I recommend:

‘Theory and Practice of Goldsmithing’ by Brepohl(we offer Orchidians
a good discount), and Mark Grimswade’s ‘Precious Metals’ (out of
print), Gold Usage, and Working in precious metals by SMith. This
last is available at http://www.abebooks.com/ I found nine copies
for sale there. best Charles

Try the “Theory and Practice of Goldsmithing” by Dr. Erhard Brephol

Hay Lee— If you are going to alloy gold I’ve got a warning for
you about Oppi Untracht’s book: -Jewelry Concepts and Technology-
The book you mention is a great one. I and many others consider it
to be the Bible, but as a cautionary note I would like to report that
the Bible may not be all correct, although I do NOT wish to dispute
the fact of its being written by the supreme being or not. My point
is I think his pennyweight to gram conversion on page 747 is
incorrect. As far a my math ability goes a pennyweight is around
1.555 grams. I think Oppie has it as 1.155. I’m sure it was just a
typo of his but when a gold alloy is concerned it can be an expensive
typo. After days of all the inane discussion by our group on
religious theology the past month, I hope we stay better focused on
jewelery making and less on unrelated personal topics. Good Luck
with your alloying.
