Basalt fiber (right) compared to glass fiber (left) Basalt fibers are produced from basalt rocks by melting them and converting the melt into fibers. Basalts are rocks of igneous origin. Basalt fibers are classified into 3 types:
Glass fiber (or glass fibre) is a material consisting of numerous extremely fine fibers of glass. Glassmakers throughout history have experimented with glass fibers, but mass manufacture of glass fiber was only made possible with the invention of finer machine tooling.

Offers update on Frontier's fiber build, says telco taking share from cable Fixed Wireless Vs. Fiber Like 'Comparing a Ferrari to a Horse,' Frontier CEO Nick Jeffery Says
The glass transition temperature of basalt is about 700 °C (1,292 °F). [4] The mechanisms controlling formation of volcanic glass are further illustrated by the two forms of basaltic glass, tachylite and sideromelane. Tachylite is opaque to transmitted light because of the abundance of tiny oxide mineral crystals suspended in the glass ...
Glass fibers have been produced for centuries, but the earliest patent was awarded to the Prussian inventor Hermann Hammesfahr (1845–1914) in the U.S. in 1880. [3] [4]Mass production of glass strands was accidentally discovered in 1932 when Games Slayter, a researcher at Owens-Illinois, directed a jet of compressed air at a stream of molten glass and produced fibers.
Mineral wool is also known as mineral cotton, mineral fiber, man-made mineral fiber (MMMF), and man-made vitreous fiber (MMVF). Specific mineral wool products are stone wool and slag wool. Europe [who?] also includes glass wool which, together with ceramic fiber, are entirely artificial fibers that can be made into different shapes and are ...
