Vulcanizing rubber is done with sulfur. Vulcanizing makes rubber stiffer and tougher.
Sulfuric acid is used in lead acid batteries, fertilizers, and insecticide.

In alchemy and along with Mercury, sulfur was considered the parent of all metals. It represented masculinity and the sun while mercury represented femininity and the moon.
