How To Get Sulfur
Pyrite weighs less than gold, and small flakes of pyrite will wash away when placed under the water. To extract the sulfur from pyrite (53% Sulfur) or other rocks such as Galena (13% Sulfur), can be done using a two pot distillation method. No water or liquid of any type is used in this process. To do this obviously you will need two pots.
