Dyson Thermal Technologies, Griffs Works, Stannington

John Dyson was manufacturing firebricks on this site by 1834 and in 1838 the business was listed as "John Dyson and Son - Black clay miners and firebrick manufacturers, Griffs House, Stannington". The business was supplied with some clay materials mined close to the works and there are adits at the back of the premises. In 2005 rising energy prices had made the gas-fired kilns uneconomic and the works was closed and manufacturing transferred to Tianjin in China. The site is very slowly being demolished.
