About PMC
There are three versions of PMC, called Original, PMC+, and PMC3. Each has special properties, as summarized here. For further details, see "ABCs of PMC" (Classes > Teacher Resources).
| Original | Ideal working properties, lowest cost | 28% shrinkage high firing temp. |
| PMC+ | Good working properties, denser | 12-15% shrinkage three firing schedules |
| PMC3 | Densest material, short working time | 12-15% shrinkage can be torch fired |
How Does it Work?
Powder metallurgy is an ancient field, and is widely used in industry. What makes PMC special is that this technology is now available for small studios and classrooms. By using only pure silver and gold, PMC is able to sinter, or fuse, in a normal atmosphere without external pressures or the use of molds. The ability to produce the tiny flakes of metal, and to mix them uniformly with water and binder bring this revolutionary material to us.
What about Cost?
Because is it a high tech material, PMC costs more than conventional silver wire and sheet. This is balanced by the amazing speed with which forms can be made, and the very low investment in tools. Also, all versions of PMC can be rehydrated before firing, so there is no waste.
Who is using PMC?
Jewelers, certainly, who immediately appreciate the ability to achieve effects that would either be time consuming or impossible through traditional methods. Ceramists and polymer clay artists naturally gravitate to PMC too, as do dollmakers, beadmakers, and artists who work with glass. PMC spans all ages, with advocates as young as grade school and as mature as... well, very mature.
How Do I Get Started?
Some people like to take a class or workshop to learn new skills, and in the Classes tab at this site you'll find a searchable listing that includes a wide range of instruction. Other people are comfortable learning on their own, perhaps using some of the books and videos published recently. You'll find them in the PMC in Print tab on the PMCguild.com site. Can't wait? You'll find short Video Clips and a free downloadable booklet called Getting Started with PMC there too.
