Flowers of sulfur (British spelling flowers of sulphur) is a very fine, bright yellow sulfur powder that is produced by sublimation and deposition. It can contain up to 30% of the amorphous allotrope of sulfur, which is the noncrystalline structure of sulfur.[1] It is known as flores sulphuris by apothecaries and in older scientific works. Natural sulfur was also known as brimstone, hence the alternative name flowers of brimstone.[2]
Flowers of sulfur has unique properties. Production occurs mainly through sublimation of natural sulfur. According to The Sulphur Institute, flowers of sulphur is widely used due to its powdered structure in rubber vulcanization, agricultural dusts, pharmaceutical products, stock feeds.[1] It can also be used in Flowers of Sulfur (FoS) Tests.
