Caption:
Cullet, made by Glastics. Glass is made by melting a mixture of various inorganic substances, principally purified sand (silica), and cooling the melt under controlled conditions to prevent crystallisation. Cullet is broken-up waste glass which is added to the original mixture at the beginning of the process.
