👉 Vesuvite is a type of volcanic glass that forms from the eruption of Mount Vesuvius in Italy. It was formed by high pressure and heat, resulting in a highly toxic mixture of silica, iron oxides, and other materials. The result is a solid substance with a hardness and a bluish-white color. Vesuvite has been used as a material for various purposes including construction, decorative artifacts, and as a source of energy.
