Most glasses are made up of about 75% silicon dioxide, which is a metalloid. Glass fall short of the characteristic that qualify an element as a metal, which includes; malleable, good thermal and electrical conductivity, ductile and fusible. Glasses, however, have other metals incorporated in the form of oxides such as Calcium oxide and sodium oxide.
