I created some 75-25 Shibuichi, poured an ingot, rolled it out and
used it in some mixed metal jewelry (with Argentium Silver, to be
specific). After pickling, the lovely coppery color has gone, leaving
a greyish silver color in its wake. I’m wondering what happened, if I
did anything wrong, and if there is any way I can restore the color
of the Shibuichi to it’s original. Thanks in advance!
