A form of Rockwool known as Pele’s hair is a geological term for volcanic glass threads or fibers formed when small particles of molten material are thrown into the air and spun out by the wind into long hair-like strands. Legend has it that Pele the Goddess of Fire and Volcanoes shed her hair to protect the natives from the fire and heat that was emmitted by erupting volcanos. The natives would cover their huts with this volcanic fiber because it would not burn and it would provide them protection from the fire.
