Slag Wool

Slag Wool
SLAG WOOL
This is an interesting byproduct from the blast furnace. It is not a textile fibre, although it is used as packing material. The process of manufacture consists in subjecting a small stream of molten slag to a strong blast of steam or compressed air. This has the effect of breaking if up into minute spherules, and each small bead particle as it is blown away carries behind it extremely delicate filaments resembling fine glass that are often 2 feet to 3 feet in length, but readily break up into smaller lengths, and in bulk look like a mass of cotton of a dirty slate colour. Slag wool has the property of great lightness combined with that of being absolutely fireproof; it is also a very good non-conductor of heat and sound.
