Visited with The Kwan, Xan Asmodi and Cunningcorgi....
History
Hendre Spar employed seven men below ground and ten men at the surface and was worked on six levels, originally accessed by a steep decline which is now flooded. Both Calcite and Fluorspar were mined, the mine was worked until 1981, when the adit was sealed.
Uses include glass making, 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 and lenses for telescopes and other optical equipment.
