About Gold . . . . Its beauty and luster are unmatched by any alloyed golds. The extreme malleability, ductility, and softness of pure gold make it practically useless for jewelry applications. The addition of indium, for instance, turns gold purple and gives gold the workability of glass. The karat indicates the amount of gold as a percentage of the total, i.e. 24 karat is 100 percent gold.
Gold standards vary around the world.
In karated gold, there is a balance of metals in the non-gold percentage. These metals provide the various colors and hardness of karated golds. Additional metals enhance properties such as castability, grain size, hardness, corrosion resistance, color, workability, ultimate strength, and others. These additions can dramatically change the properties of the karated metal for better or worse. Knowing how the additions will affect the metal greatly enhances the possibility of a superior final product.
