John Hall Ltd. of Dukinfield mined coal, fireclay and shale from 1911 to 1937 at a mine in the fields close to the Clarence Mill in Bollington. The shale which when fired turned red was used to make chimney pots, tiles and drain pipes. This is the entrance to the adit which led to a shaft situated higher up the hill and allowed the loaded tubs to be brought out to the canal wharf hauled by a horse. The adit entrance and shaft are actually just in Adlington.

Giscol (registered as a company in 1888) was the trading name of the Glasgow Iron & Steel Company Limited an iron and steel producer with foundries and iron works situated in West Central Scotland. Today the name is used by Caradale Traditional Brick Ltd after a management buyout of the company in 1997. Today the company has two brickworks - the Etna works at Armadale, West Lothian and the Mayfield works at Carluke, Lanarkshire. Caradale is unique in the traditional brick making sector in that it uses shale clays. They're more difficult to work but they make a harder, more durable brick suitable for the extremes of British weather.
