This PMC3 developed and manufactured by Mitsubishi Materials is a renown fine silver clay for jewellery making. It contains very fine silver particles, combined with water and a non-toxic, organic binder, that when dried and heated using a kiln or a torch, will burn away the binder, causing the particles to sinter and become a solid metal. PMC3 is easy to work with and has a soft texture. After sintering, it has a shrinking rate of about 10-15% and becomes 99.9% pure silver. An eco-friendly product as it contains recycled silver.PMC3 has a quick-firing time at a lower temperature than any other type of PMC. It can be fired for as fast as 10 minutes at the appropriate temperature. This product can be rolled, cut, and turn into different kinds of shapes, and can be combined with glass, some gemstones, and ceramics.Product Data:• Silver Weight: 5g• Clay Weight: 5.6g• Shrinkage: 10-15%Firing Temperature:• 700°C (1292°F) for 10 mins.• 650°C (1202°F) for 20 mins.• 600°C (1112°F) for 30 mins. Composition:• Metal powder (90%)• Water and organic binder (10%)Please note: Keep out of the reach of children.
