Adshead's 1851 map shows 'Pincoffs & Co's Chemical Works' on Gloucester Street, close to Oxford Road Station. It backed onto the Rochdale Canal, and was bounded on the west by the Caledonia Foundry of Glasgow & Co, and on the east by a coal yard.
1857 Simon Pincoffs was granted a provisional patent for 'treating of madder, &c.'
