About this product
Forehearth lines rarely run straight: they branch after the distributor, narrow as they approach the machine and change level. Using standard blocks at these points multiplies the joints, and every joint is a potential leak. Special shapes resolve the transitions in one piece and cut the joint count to a minimum; dimensions are taken directly from the channel drawing.
Material
Alpha–beta alumina and jargal blocks are fused cast from high-purity alumina. Because they contain no zirconia, they do not seed the melt with zircon and carry a very low risk of stones and blisters in the finished glass. They are the preferred lining for superstructure, forehearth channels and feeder zones, particularly in container and flat glass production.

- Channel bends and branch points
