Red and white gold - color contrast


#1

Hi,

is there a possibility of getting a high color contrast in a 18K
red and white gold mokume ring? I’ve made one and am a little
disappointed of the colors, because the red gold looks very pale
red and the white gold (Pd-white) has the gray color one knows of
palladium. What I wanted to achieve is a really red ring with
bright white lines. Is there any kind of treatment to get the
colors I wanted? I could live with that pale red, but what I
really don’t like is the white gold’s gray color. I think there
must be a way to get it more whitish.

TIA,
Sabine

protect the metal better during soldering red gold will lose
color and white gold will gray if you get them to hot especially
when you solder the 2 together, try eutectic solder as the two
alloy will react as a bimetal making solder flow difficult.
causing a longer higher heat application to get results.there is
a temp chart in the book of alloys, don’t know the author. hope
that helps…John the Ringman

Since I made Mokume there really was high heat when I fused
those two metals together. Is there really no way to get the red
color back? Can’t believe it…

Sabine: try to pickle… soak in cold cyanide if that does not
work , if that doenot work try a hot shot into the pickle (ring
hot) and quenched very fast this has a tendancy to raise the
copper on the outside. I have found that two different metals
will pickup copper from the pickle pot if I leave a piece of
copper in it. perhaps that will help…once its gone it
usually is gone for good…Ringman John
