Meet the newest generation of PMC on the market PMC™ PRO. It is the strongest and most dense silver clay on the market. It’s perfect for anything that requires more strength like rings and bracelet components. Its bending strength is 5x that of PMC3 and is more resistant to scratching as well.
Very similar to PMC Original in that it can be modeled easily, takes texture beautifully, drapes extremely well, and can be carved easily. Because it is stronger in it’s greenware state, you can carve and sand without the fragility of some of the other clays.
Do not mix with other clays in their clay form. However, if you have a piece made from PMC+ or PMC3 and want to attach them together or fire them as one piece with PMC PRO, fire the piece first at 1000°F for 30 minutes on an open shelf firing. This will sinter the PMC+ or PMC3. Then do a second firing in carbon at 1400°F for 30 minutes to sinter the PMC™ PRO.
You will need the same tools that you use for PMC or Art Clay, just be sure to clean them between using different types of clay. Keep dedicated sanding tools for just PMC™ PRO.
PMC™ PRO must be fired in a kiln in carbon at 1400°F (760°C) for 1 hour. 1/2” of coconut carbon should be placed around each piece in a firing container, such as stainless steel. The lid should be propped, a hole drilled, or a place a piece of 1/8” fiber paper cut to fit inside the container for the lid. Do not use too much carbon as this reduces the temperature. If you are firing a large load or large pieces, fire for 2 hours.
You may wish to opt for an open shelf firing (similar to COPPRclay and BRONZclay firings) at 1400°F (760°C) for 30 minutes and then do a second firing in the carbon. If you find that your pieces are not sintering you may wish to try this method to insure firing temperature.
Use traditional methods for finishing metal clay (tumbler, polishing lathe, magnetic polisher, rotary tool, or by hand). You may also patina PMC PRO as you would the other PMC or Art Clay versions.
Treat PMC™ PRO as sterling silver when enameling or applying gold such as Keum Boo. You will want to raise the fine silver skin first or depletion gild. For soldering, you will only want to use Easy or Medium Solder.
