... This story is really funny, why you didn=B4t tell them that white gold is= only=20 found in full moon nights and rose gold in dawn? :-)) Ah, here's a story to tell them: "Gold takes on the color of the first light to hit it. Most miners' headlamps are battery powered flashlight sort of things that give a yellow light, so most gold comes out yellow. In some mines they use mirrors to bring in sunlight so they can get very light yellow gold and we call it 'white gold'. Mirroring in moonlight was tried to get _really_ white gold, but it made silver, so they don't do that any more. Rose gold is produced at dawn and sunset in those same mirror mines. Some mines have experimented with using multicolored lasers but that produced opals and Australia already has enough of those." -- Carl West http://carl.west.home.comcast.net change the 'DOT' to '.' to email me "Clutter"?

The discussion got me thinking of a design using a yellow gold base with white gold decoration soldered on. Easy to do. Both yellow gold solders or white gold solders can be used. The decision is mostly one of which color solder will better fit the design needs. I'm thinking here of a true white gold or even a high-nickle gold alloy since the white gold wouldn't be resting in constant contact with the skin. Um. So just what do you consider "true" white gold? Do please remember that there is no pure gold that is anything other than bright yellow when in it's normal massive metallic form as we use it.. All white gold alloys are mixes of yellow gold with other metals, usually either using nickle or palladium to "bleach" out the yellow color to an acceptable degree of whiteness. So what do you consider "true"? I'm reminded of one only somewhat humerous interchange with a customer once, who'd been told by some ignorant mall store sales girl, or perhaps it was from some home shopping channel thing on TV (don't recall which) , that white gold came from a different type of gold mine than yellow gold... No amount of careful discussion or detailed explanation of alloying could convince this woman that white gold was an alloy of ordinary and usual yellow gold with other metals to make it white. Peter That sounds similar to the last paragraph written here http://www.24carat.co.uk/whatiswhitegold.html Enjoy! |

Gee, that's funny -- I always used 18k alloyed with palladium and it
was nice and ductile, brilliant white (like 19k gold solder, eh? Never had to rhodium it, great stuff. I know I must have tried commercial alloys when I was new to all this, but never had much luck with it as I remember. 10% Irid-platinum or 5% rhodium-platinum is better.

There is no such thing as white, white gold. Besides which, it is a contradiction in terms. Don't use it. If you want white, use Platinum, Silver, or (if possible) stainless steel. White gold! It is such "Dreck"! Abrasha http://www.abrasha.com |
