Description

Small or broken pieces of glass. Ancient glass manufacturers incorporated cullet in their work. Glass has a lower melting point than its components. When glass pieces and raw materials are mixed and heated, the glass pieces melt first and act as a solvent for the sand and metal oxides. Thus, the glass pieces reduce the time and energy required for making glass. Currently, cullet refers to glass fragments gathered for recycling.
