Glass

A jar made of soda-lime glass. Although transparent in thin sections, the glass is greenish-blue in thick sections from impurities. Bubbles remained trapped in the glass as it cooled from a liquid, through the glass transition, becoming a non-crystalline solid.

Glass is a non-crystalline amorphous solid that is often transparent and has widespread practical, technological, and decorative usage in, for example, window panes, tableware, and optoelectronics.
