Fused cast basalt
Basalt features one of the highest hardness among minerals currently in existence.
Stone casting or basalt casting is a material that is produced in the process of melting basalt and natural stone, which is then poured into sand and metal molds, and centrifugal casting molds as well.
Due to its excellent quality, rare composition and high strength, fused cast basalt is used to produce a wide range of different products, such as:
- stone-cast plates made of fused basalt
- YIG gutters and other forms
- Pipes from fused cast basalt
- Bricks from fused cast basalt
- Shaped basalt casting according to customer’s drawings

Properties of fused cast basalt:
The combination of these properties allows the use of stone-cast products from fused basalt in places subject to intense abrasive wear, as well as wear that occurs from exposure to chemically aggressive environments (alkalis, acids).
