With PMC® Flex™, you can work, roll, cut and shape this fine silver metal clay like modeling clay and enjoy a much longer working time—weeks, if need be!
The clay firms up somewhat but stays pliable enough to bend, twist, shape--even join edges with slip—up to a month later. Then, when you're ready, fire the clay to produce a pure fine-silver object.
(NOTE: You won't be able to ball-up and re-roll the clay; to do that, you'll need to rehydrate the clay and begin again).
Composition: Metal powder (90%), water and organic binder (10%) Firing temperature:
1,650°F (899°C) for two hours to achieve highest hardness and maximum durability;
or 1,470°F (800°C) for 30 minutes;
or 1,560°F (850°C) for 20 minutes;
or 1,650°F (900°C) for 10 minutes.
Melting point: 960°C (1,762°F) Density after firing: 9.15 S.G. (rolled silver = 10.5 S.G.)
please note: • Every variety of PMC® is sold by the metal weight, not the weight that includes the water and binders that burn off during firing. You get every gram of precious metal you pay for from PMC. • PMC® has a strong adverse reaction to contact with aluminum. Do not use aluminum tools or allow your PMC to come into contact with any aluminum object.
