EZ925 Sterling Silver

EZ925 is a sterling silver alloy clay, made from 92.5% silver and 7.5% copper, delivering the durability of traditional sterling with the creative freedom of metal clay. Unlike other 925 sterling silver clays, it fires on an open kiln shelf in a single firing - no carbon required.

Phoenix Torch Fireable Clay - Fine Silver 

Phoenix Torch Fireable Clay is a great, all purpose fine silver metal clay with excellent working properties and can be fired with a kiln or torch. Because it can fire at low temperatures, it is the perfect clay for co-firing with glass. Its density provides strength in the greenware state, and after firing, it is ideal for soldering, enameling, bending and polishes to a beautiful high shine.

FS999 Fine Silver

FS999 Fine Silver Metal Clay comes right out of the package ready to form, fire and finish, with excellent working properties. Invented by Bill Struve from Metal Adventures, the inventor of BRONZclay™ , COPPRclay™ and EZ960 Sterling Silver Clay.

The first thing you will notice is its smooth, creamy consistency. The clay accepts and telegraphs the smallest of details in textures very well. It is easy to roll and form, and is surprisingly non-sticky. It also has a high moisture content, making it easy to work with in its wet form. 

EZ960 Sterling Silver 

This is the first sterling silver metal clay that comes right out of the package ready to form, fire and finish with no two part mixing and no carbon required.
Invented by Bill Struve from Metal Adventures, the inventor of BRONZclay™ and COPPRclay™.

EZ960 is a great, all purpose metal clay with excellent working properties. Because the clay is a sterling silver alloy, one of its best attributes is its post firing strength, in comparison to fine silver. This inherent strength makes EZ960 the perfect choice for jewelry that takes lots of abuse, such as rings and bracelets. It is also great for jewelry with findings and components such as bails, hinges and clasps, as well as delicate pieces that would benefit from the strength of sterling silver.
