Uses of Fluorspar
Fluorspar was mainly used as a flux in iron and steel making. It is also used in the chemical industry to make
fluorine to add to drinking water and toothpaste. Fluorspar was also used to make chloro-fluorocarbons, which
used to be used as aerosol propellants and in fridges, but are now blamed for destroying the ozone layer.
Some fluorspar from Boltsburn mine was special because it was used for making lenses for telescopes and
other optical equipment. It was also used bu lead miners to make spar boxes.
