Basalt Fibers: Alternative to Glass? | CompositesWorld
Basalt fiber is produced in a continuous process similar in many respects to that used to make glass fibers. Quarried basalt rock is first crushed, then washed and loaded into a bin attached to feeders that move the material into melting baths in gas-heated furnaces.

Melting Rocks
The presence of water in the rock is important to lower the melting temperature. Other important factors are time and grain size. The smaller the grain size and the longer you hold it at the temperature, the more likely the rock will melt.

Basalt | Properties, Formation, Composition, Uses
Basalt is a type of volcanic rock that is formed from the solidification of molten lava. It is an igneous rock, meaning it is formed through the cooling and solidification of magma or lava. Basalt is one of the most common rock types on Earth, and it can be found in various locations around the world, both on land and under the ocean floor.
