Basalt Fibers: Alternative to Glass?
The process requires only a single feed line to carry crushed basalt rock into the melt furnace. On the other hand, basalt fiber manufacturers have less direct control over the purity and consistency of the raw basalt stone. While basalt and glass are both silicates, molten glass, when cooled, forms a noncrystalline solid.
