Keys to finishing PMC to metalsmithing standards
Plan to work on the piece for a longer time.
Plan to work with the piece in its leather hard state:
– file the edges with the pink nail sanding board, you can find these at Walgreens. On line you can buy them from PMC Tool and Supply.
– trim interior or undercut areas with a blade like tool. Some folks like X-acto knives. I happen to not care for them myself. I use the “carving tool,” as seen on my site for trimming, applying slip, refining, basically everything.
While the PMC is still damp, sand it using a damp, but not sopping wet, eye shadow brush. Dunk the eye shadow brush in water, squeeze out the excess and then “wet sand.” You can buy these from Target, K-mart, Walgreens, Sally Beauty Supply, etc.
Complete as many tasks as possible while the material is in the clay form, but after it’s fired, don’t necessarily consider it done. If any filing, sanding or shaping is needed, it can still be done. PMC + (and other forumulas and brands) can be sanded, filed, soldered, drilled, and dapped. Sometimes it is easier to shape the PMC after firing than to try to fire it in a specific shape.
I have dapped after firing: rings, (rounding up), a spoon bowl, cuff bracelet, and probably more things that aren’t coming to mind at the moment. The spoon I did in an hydraulic press.
