Here is an example of a recipe from Tiffany.
"Mix 12 oz. silver nitrate, 4 oz. uranium, 4 oz. manganese, 4 oz. arsenic, 12 oz. potash nitrate. Add to 100 lb. of molten glass. Combine with artistry, chemistry, and secrecy. The result: “Gold Lustre,” a signature glass of Louis Comfort Tiffany, also called iridescent for its lustrous finish."
