Borax Dish
When mixing with water using the borax dish this forms a flux used during the soldering of gold or silver. The cone of borax is used with the flat bottomed borax dish by adding a little water and rubbing the bottom of the cone in a circular motion in the dish. The cone will dry out after use and can be used time and time again, eventually producing enough flux for thousands of joints.
