Quartz is the mineral from which plaster and other similar building materials are composed. Luster is the external expression of a mineral's internal orderly arrangement of atoms. Uncombined atoms have the same number of neutrons as protons. The structure of the silicon-oxygen tetrahedron consists of four oxygen atoms surrounding a smaller silicon atom. Vitreous, pearly, and silky are types of metallic lusters.
Reserves are already-identified mineral deposits from which minerals can be extracted profitably.
