Yellower 18k gold alloy


#21

Found a green gold wheat chain in 2.8 mm…thanks!


#22

Hi, source of copper was pure copper (.999)…not sure about the oxygen question…thanks


#23

As long as the copper is .999 and has no silicon, selenium, boron etc. It shouldn’t be a problem right? I mean the oxygen should diffuse out when melted and resolidified…

Thanks for the response by the way.


#24

Where did you find the wheat chain? Herco?

Yes, Herco!


#26

Oxygen is a gas, so not sure that it comes into play within copper material itself…

I used to make my own alloy material. My old formula was 2/3 silver to 1/3 copper for working a real rich 18K gold. In the last 5 years or so, I’ve been using Stuller’s 18k “Royal Yellow” alloy material. It seems to work a lot better than my old alloy, also a bit tougher.


#28

Why do 18K alloys not have as much copper as 10-14 karat? In 18K you can a large amount of silver and it will still be bright and yellow compared to 10-14 karat gold which have a lot of copper, is it customary or is there some reason that 10-14 karat have so much copper? Can 10-14 karat alloys have a lot of silver too?

While we are on the subject of alloying gold I’d like to suggest the following book. Jewelry Metals A Guide To Working With Common Alloys. It’s published by MJSA and written by James Binnion who in MHO is a stone cold genius. No studio should be without it.

That sounds like a great book! Does it include recipes (I am always searching for new ones)


#31

It does not have specific recipes. But it is a very valuable resource that explains the science behind the alloys as well as a what the alloying elements do. I can’t recommend it enough.
