Calumite Slag is a waste by-product of the iron and steel industry utilized in the production of glass. Intensive research has resulted in a successful procedure to minimize slag composition variations to produce consistent and efficient glassmaking raw materials. The proper application of Calumite Slag in a glass batch lowers melting temperatures or increases glass load in a furnace without requiring more fuel.

Benefits include:

  • Extended furnace life
  • Reduces excess retention of gases
  • Enhances control of oxidizing levels in the melting operation
  • Provides stability and homogeneity of the glass
  • Simplifies batch formulation
