CONTAINER GLASS

Magflux®

Magflux® is a blended, refined form of blast furnace slag. Its mineral composition is a mixture of Akermenite, Gehlenite and small amounts of Anorthite.

Magflux® is added to a glass batch as a fining agent and its reducing action helps liberate retained gases from the glass batch which may cause defects such as seeds and blisters. Also, the addition of Magflux® forms a lower eutectic with silica resulting in a lower melting temperature and lower energy costs. Furthermore, a more active melt is produced thus improving homogeneity in the batch temperature and composition.
