Black Diamond's Black Gold Chalk is made from 90% White Gold Chalk and 10% Pure Gold Chalk, which is a highly porous form of Magnesium Carbonate that contains Upsalite. In other, less science-based terms, this chalk absorbs twice the moisture as regular chalk and is engineered to make you climb at least a V-grade harder. Once again, science is here to help you stick the move.
