A mineral:
a) must have an identifiable chemical composition.
b) This includes solids with a compositions that can be identified but not expressed by an exact chemical formula; an example is glass must be inorganic.
c) This excludes the vast number of organic compounds produced by living matter. must be naturally formed or formed from naturally occuring compounds.
d) This includes the vast numbers of substances that can be produced in a laboratory but are not found in nature. must be a solid or a liquid.
