· Since cullet glass is a solid mixture of silica, soda ash, and limestone, the cullet melts at a lower temperature than virgin glass materials. When recycled glass cullet is mixed in with raw materials to manufacture glass, the melting point drops from between 2550 to 2900 °F to between 2250 and 2350 °F, which is a huge energy savings.
