The 18K yellow gold ring came out of the ultrasonic white! Polished
an area to see if it was some weird galvanic reaction…still white.
So I figured it might be a yellow plated white gold piece and the
plating just flaked off, and I’ll have to re-gild it. Did my
soldering and whoa its yellow again! I’ve had numerous other pieces
in the same bath with no change whatsoever. I wonder if I just
exposed myself to a big dose of mercury vapors? But how it might have
gotten there I dunno.
Cue the Twilight Zone theme.
