Glass wool 6
Glass wool is a fibrous inorganic substance (silicates) made primarily from rock, slag, glass, or other processed minerals. It is widely used as a thermal insulation material. [1] Glass wool plugs are often used in GC inlet liners to improve sample vaporization and to keep non-volatile material from entering the column.
Slag Resource Recovery Via Air Granulation
the high glass contents could be maintained at a larger scale. As atomization is scaled-up, the surface area of the SAPs decreases in relation to the slag amount processed and this decreases the slag cooling rate. Lower slag cooling rates might lower the glass content of the atomized slag product, and thus reduce its viability as a cement substi-

Everything You Need to Know About Slag Glass
Slag glass was first created in England in the 1880s as an opaque brown with white streaks from iron slag. Sowerby, a popular pressed glass manufacturer in the UK during this time frame, was the first manufacturer to start producing slag glass. They started with brown glass, but also produced purple, yellow, green, and blue.
