Calumite Limited supplies glassmakers in the UK and overseas with Calumite, a refined blast furnace slag. Calumite is a glassy calcium-alumina-silicate that is used as a raw material in all types of soda-lime-silica glassmaking. Less energy is required to melt a Calumite containing batch, which can be used to reduce energy consumption, reduce furnace temperatures or increase furnace pull. In addition, Calumite is a refining agent, containing sulphur as sulphide which works to reduce seed count and improve glass quality.
