You're looking at 26.9 grammes of Precious Metal Clay Sterling (25g Metal Weight, 92.5% Silver) that creates and exceptionally strong silver ally.
PMC™ Sterling combines microscopic particles of metals in the precise proportions of 92.5% silver with 7.5% copper—the same 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.
Please note PMC Sterling will require sintering an a bed of activated carbon for optimal results.
PMC Sterling is manufactured in Japan by Mitsubishi Materials.
Comes in an air-tight resealable container. Detailed English instructions in the pack.
