Dyehouse
A dyehouse coloured wool, yarn or cloth in large vats heated over fires, using plant dyes such as woad for blue and madder for red, with mordants to fix colour. It needed abundant water and made a mess of nearby streams. Dyeing was an organised trade in the 12th century: the London Dyers' guild existed then, though its royal charter came only in 1471.
Caveats (confidence: medium)
Specific 12th-century dyehouse sites are not identified in the sources consulted; alum, the main mordant, was imported.
