Sterling silver is simply an alloyed form of silver which contains in this case 96% silver and 4% copper. The copper makes your jewellery stronger and more durable compared to fine silver.
We recommend using Project X 960 silver clay for rings, bracelets and other pieces that need to retain their beauty and lustrous appearance for a long time. And even when scratches or scuffs appear, sterling silver can be easily restored to its original luster.
Working with Project X 960 is exactly the same as working with any other fine silver clay.
Project X 960 must be fired in an electric kiln.
