I make pins out of brass, copper, and nickel-silver, using the
"married metals" technique. However, when the pins are polished
to a mirror finish, the color contrast among the metals is
entirely lost; indeed, one can hardly see any color at all. If
I oxidize them (using Jax-Black, or the like), the color
contrast shows up much better, but the pin loses brightness
(which is OK with me, but a lot of customers like “bright”).
Does anyone have suggestions for other surface treatments for
married metals which would retain/heighten the color contrast?
(I do not care for lacquers, etc., because sooner or later they
start to wear off and the finish becomes patchy.)
Thanks in advance!
