Add 24K gold to our high-purity alloys to create the karat and color that you desire (18K = 75% fine gold, 25% alloy; 14K = 58.33% fine gold, 41.67% alloy; 10K = 41.67% fine gold, 58.33% alloy). Can also be used to lower karat. Sold in shot form and packaged in preweighed bags. Both White Alloys are in 10 troy ounce packages; both Yellow Alloys are in 5 troy ounce packages.
