Grog
Grog is a pre-fired, crushed refractory material used as an aggregate in the manufacture of new refractory bricks and castables. By using grog, manufacturers can reduce shrinkage during firing and improve the dimensional stability of the final product.
Our grog is produced by crushing and sizing previously fired refractory materials. The result is a stable, pre-shrunk aggregate that enhances the quality and consistency of refractory products during manufacturing.
Grog is an essential raw material for refractory manufacturers who need to control shrinkage, improve thermal shock resistance, and produce dimensionally accurate bricks and shapes.
Common Applications
- Refractory brick manufacturing
- Castable refractory production
- Kiln furniture manufacturing
- Ceramic and pottery production
- Refractory mortar formulation
- Thermal shock-resistant products
