PMC is available
in three versions: standard PMC, which provides the best modeling
and greater shrinkage characteristics; PMC+, which is denser,
has less shrinkage and offers several firing options; and
PMC3. All three kinds of clay are worked with the same tools,
may be fired in the same kiln, and can be finished in the
same ways.
Three kinds
of PMC
Precious Metal
Clay is now available in three different versions called PMC,
PMC+ and PMC3. Each is sold in lump form; PMC+ is also sold
as slip(liquid clay), paste, paper and syringe. Each version
offers its own unique benefits.
PMC
has ideal workability and a relatively high shrinkage that
allows wonderful detail. It is the least expensive version.
PMC+
fires very quickly and results in a dense and durable material.
It also allows for firing at three different temperatures,
the lowest of which makes certain implants and enamels possible.
PMC3
fires at an even lower temperature (1290ºF) which not
only allows implants but means alternative, low-tech firing
devices become possible.
Not every artist
will need all three versions. Some find a preference and stick
with it, while others use different materials depending on
the nature of their work.
How do they
do it? In the end is it all silver?
Yes, all three
versions yield the same metal, 100% silver. The difference
is not in the ingredients but in the shape of the particles.
