Feldspars Feldspars unquestionably unquestionably really really are are a a common common example: example: Good Good chemistry chemistry is is always an an alkali alkali aluminum aluminum silicate, sodium sodium or or potassium. potassium. always only silicate, in in which only for for the which the the benefit benefit of of mankind. the alkali alkali metal mankind. Anorthoclase Anorthoclase is is clearly metal is is interchangeably interchangeably either clearly either In In law, law, " "chemical obtaining obtaining a a precise regulation regulation Achieve substances" substances" and two two contain contain multiple chemical compounds" compounds" can precise composition composition or or manufacturing Achieve defines defines "monoconstituent and "substances "substances of of unknown multiple chemical chemical compounds can include include both manufacturing process.
