GOLD-Using PMC Gold
Artists who have used other versions of PMC before will find that the gold is slightly denser. This will make it feel a little stiffer, and explains why it will take longer for water to penetrate. Before using, knead the material while it is still in its plastic wrapping to loosen the structure. Add small amounts of water to compensate for drying during working, but be conservative. Seal unused material to retain moisture. Use wood, plastic, rubber, and steel tools. Finishing is done just like any precious metal, including abrasives, tumbling, hand burnishing, and polishing compounds. PMC Gold can be soldered with any gold solder below 22 karat.
Firing PMC Gold
As with other metal clays, allow the work to dry, preferably overnight. Drying may be hastened with moderate heat. The recommended firing apparatus is a programmable electric kiln, which provides dependable control. Schedule A: 900? C (1650? F) at least 10 minutes Schedule B: 850? C (1560? F) at least 30 minutes Schedule C: 750? C (1380? F) at least 60 minutes Schedule D: 700? C (1290? F) at least 90 minutes
It is also possible to fire PMC Gold with any jewelers torch. Dry completely, set work on a soldering pad, and bring to a red glow. Hold at this temperature for at least two minutes.
