GRAIN karat gold, platinum, and palladium

Stuller karat gold casting grains are produced using only high purity raw materials. All metals used in Stuller alloys are certified to exceed 0.999+ in metallic purity. Each melt is analyzed by traditional fire assay and x-ray fluorescence techniques to ensure quality and consistency. Our karat gold casting alloys contain special additives that enhance casting characteristics, provide for less rejects and finishing work, and increase reusability factors. Grain for rolling is formulated specifically for sheet production and wire drawing applications.
