Soda-feldspar as known as Albite is a plagioclase feldspar mineral. It is the sodium endmember of the plagioclase solid solution series. As such it represents a plagioclase with less than 10% anorthite content. The pure albite endmember has the formula NaAlSi3O8. Soda Feldspar is generally a clean white m ineral that sources sodium, alumina and silica along with some potassium and calcium.
