👉 Pyromorphite is a mineral that forms when molten metal, such as iron, burns. It typically occurs in the Earth's crust and can be found in various types of rocks, including granite, gneiss, and schist. The specific chemical composition and crystal structure of pyromorphite are not well understood and they have been studied only through laboratory experiments and observations. However, it is known that pyromorphite has a high melting point (around 1200
