This is a reflected light micrograph of a polished, carbon coated albite crystal. The identifying etched label, which is a feature of our standards, is invaluable for navigating in an electron beam instrument. Albite is the sodium rich member of the plagioclase felspars and is a useful standard for felspars and other aluminosilicates. The sodium shows a tendency to migrate under high beam currents, so caution is advised. The name refers to its white color (Latin - albus).
