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.
- 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
