Glass
Glass is defined as 'a hard, transparent material, used to make windows, bottles, and other objects'[1]. It is formed from a melt by cooling to rigidity without crystallization and is a usually transparent or translucent material consisting typically of a mixture of silicates'[2].
Glass is a resource that can be continuously recycled without a decline in quality. The four main constituents of glass are sand, soda ash, limestone and other additives for colour or special treatments, these materials are not in shortage but the quarrying required to obtain them is energy-intensive and has consequential environmental impacts[3].
