Using PMC Gold 
This 22 karat material is an alloy of 91.7% gold and
8.3% silver, refined into microscopic particles that
fuse at relatively low temperatures. This unique combination
provides rich yellow color and unusual strength. PMC
Gold can be used alone, or as a decorative element on
silver items. Consider these possibilities: Co-fire
silver and gold PMC side by side Layer silver and gold
to make precious metal woodgrain patterns Solder or
fuse PMC Gold elements to fabricated and cast items.
As with silver PMC, you can rehydrate with clean water,
and make your own slip from sanding dust. Because Gold
PMC has the working properties of PMC3, we suggest that
newcomers test ideas in that material. Further instructions
and tips available at www.PMCguild.com.
Working with 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: 900º C (1650º F) at least 10 minutes
Schedule B: 850º C (1560º F) at least 30 minutes
Schedule C: 750º C (1380º F) at least 60 minutes
Schedule D: 700º C (1290º F) at least 90 minutes
Torch Firing
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.
