👉 Gmelinite is a mineral that is found in the Earth's crust and is composed of two minerals, mica (Mica) and dolomite (Dolomite). Mica has a high melting point and is used as a fireproofing material due to its low heat conductive properties. Dolomite is another type of mica and is also used for fireproofing purposes due to its low thermal conductivity. Gmelinite is often associated with the formation of igneous rocks, such
