For Best Results with MPK Lead Free Pewter
MPK is also antimony free which makes it more pliable than 92-8. MPK will run about 40 to 50 ppm in lead. Either alloy works well in either silicone or vulcanized rubber, sand and bronze molds. Some customers tell me that they even cast into plaster. Both metals run approximately .27 pounds per cubic inch.
