Glass

Glass is a solid material that is typically transparent or translucent, made by heating a mixture of silica (sand), soda (sodium carbonate), and lime (calcium oxide) to high temperatures until it melts and then allowing it to cool into a rigid structure. The cooling process does not allow for the formation of a crystalline structure, which is why glass is classified as an amorphous solid. The properties of glass can vary widely based on its composition and the treatment it undergoes.

"Glass applications" typically refer to software applications designed to run on smart eyewear like Google Glass or similar augmented reality (AR) devices.
