Awesomeness thats Green baby, Green!

Yes, its green! Art Clay & Precious Metal Clay (PMC) are recycled products which reclaim a variety of different metals. 

Art Clay is manufactured in Japan by Aida Chemical Industries. Aida Chemical Industries is a family owned company that recycles and reclaims metals, including the precious metals gold and silver. Aida Chemical Industries is a "green" company, it collects metals which already have been used and reclaims these metals. Such items as computer circuit boards and silver from photographic supplies are processed in tremendous quantities every year. A portion of this harvest becomes Art Clay Silver and Art Clay Gold. Aida combines these reclaimed metals with non-toxic, organic binders. The result is a product which can be handled safely. Every effort has been made to assure the safety of artists using Art Clay. Even the production processes used to create Art Clay are designed to have minimal effects on the environment. (yah, we love you Art Clay!)  

Precious Metal Clay, PMC, is produced by Mitsubishi Materials of Japan. Microscopic particles of silver are mixed with a moist binder to create a material that has the feel and working properties of modeling clay. Unlike Art Clay is seems PMC is not 100% reclaimed and/or recycled and I'm finding it hard to find info on the exact make up of reclaimed materials for PMC.

I'll keep researching and if any one out there has any hard facts, I'd love to hear them!
