Description:
Reprint nach der EA von 1995.- Along the nearby Newhouse Gill, which descends from Grey Knotts, is a graphite mine which was opened after the discovery of graphite there in 1555.[6] The extracted graphite was eventually used to supply the Derwent Cumberland Pencil Company factory in Keswick. The commercial mining of the unusual solid form of graphite found near the hamlet of Seathwaite ceased around 1891 when veins of the solid graphite became harder to find. In addition, around that time the Keswick pencil factories had switched to making pencil pigments out of the familiar combination of clay powder and graphite powder. Graphite powder could be mined and imported from elsewhere. Text: engl.
