I have made this alloy, but what a pain in the neck. Just melt the
iron, and toss in your gold…and kiss that gold good-by.
What you get is a gold alloy, that looks quite like a gray gold
alloy. Add a little heat with your torch, and it will turn blue on
the surface…just like steel will. But steel is easier to work with
than this stuff. It will not bend, roll out, or draw down. But it is
If blue is the color that you want to work with, why not save
yourself a lot of grief and just use steel. Almost any steel will do,
except stainless. You can make it blue, black, even a plum color.
You can inlay it, cast it in place, or use it as a background for
inlay. And just like 18k blue gold, the color exists only on the
surface. Not the choice of metal for a ring…
I have a great formula for blackening steel, if anyone is interested.
Cartier, and others, used this technique in the 30’s. You can do all
your gold work on and around the steel, even set stones. The
blackening is done last, after all polishing. Only the steel is
blackened. You can control the amount of blackening too, from
hematite gray to coal black. It’s quite durable, but it will
scratch. If it should scratch, you can easily repair it. This is a
lot easier than colored golds.
Unless you have the soul of an alchemist and are drawn to the fire…
