Sulfur

Sulfur is a non-metal with wide use in industry, it is believed to be the ninth most abundant chemical element in the universe. In general, its color is lemon yellow, but some deposits can be brownish. It was one of the first mineralogical materials to be identified. In the Bible, there were already references to him. Sulfur can occur isolated in nature, without being associated with any other element. It is therefore classified as a native element. It is widely used in the industry. It is a component of sulfuric acid, which is used in the production of detergents, fertilizers, paints and pigments. It is also an important component in the vulcanization (strengthening) of rubber. Cleaning sulfur crystals is not advisable, as they are very delicate: the element is extremely sensitive to heat, melting at 113ºC. It can still crack under the hot sun or even with the heat of your hand. Sulfur originates from volatile gases exhaled by volcanoes. When cooled, it usually changes from a gaseous state to a solid, without stopping in the liquid state (sublimation).
