PMC Sterling™ combines microscopic particles of metals in the
precise proportions of 92.5% silver with 7.5% copper—the
proportions as traditional sterling. The metal powders are mixed
with water and a nontoxic binder to create a material that can be
worked as easily as modeling clay. Objects can be made with simple
tools, then they are dried and sometimes refined further. The pieces
are then taken through a two-step firing process that drives off the
water, burns away the binder, and fuses the particles into solid metal.
The result has properties very similar to cast sterling silver. It can be
polished, soldered, and patented just like any other precious metal.
