A glass does not have to be a silicate. Plexiglas is an example of an organic glass. Other classes of materials can be glasses, as well, including metals, and semiconductors. In each case, the combination of composition and processing conditions combine to create a material that is truly a solid, but is disordered at or near the molecular or atomic scale.
