It is a modern day form of powdered metallurgy used to create jewelry in fine silver, sterling silver, gold, bronze, copper and more.  

The metal is ground down to fine particles, combined with an organic binder and mixed with water to make a clay-like substance.  

The metal in this clay state can be shaped, constructed and carved before it is dried to a solid state and fired in a kiln.  The firing process is different for each metal to properly sinter, but in the end the binder burns out and all that is left is solid metal.  

The metal is then finished using any number of traditional and contemporary metal working techniques including hammering, piercing, filing, bending, soldering, enameling, stone setting, adding patinas and polishing.
