LabelGlass is a non-crystalline amorphous solid traditionally made of silica mixed with sodium oxide, calcium oxide and other minerals that are added to control its malleability and color. Glass has unusual physical properties: its atomic structure resembles a super-cooled liquid but at room temperature it behaves like a solid. Glass has historically been appreciated for its translucency and low permeability to liquids. Today new types of glass are being exploited for their beneficial optoelectronic and thermomechanical properties.
