This specimen consists of a large chunk of chalky, white material that makes me think of massive borax which acts as a base for a crust of crystalline Sulfur. The crystals that make up the crust are very small (0.1" or 3 mm diameter max.) and heavily intergrown, but show definite and well-formed crystal form. Like most Sulfur crystals, they show an intense yellow color, a vitreous luster, and reasonably good transparence and clarity. They cover up about 15-20% of the host rock's total surface area, and show relatively little damage.
