Manuscript sample record books relating to cloth dyeing in West Yorkshire

Consecutive volumes contain manuscript notes relating to dye testing, testing of oils, acids and soaps, grease extraction, water analysis and boiler water tests. They give copious analyses, as well as recipes for dyeing particular textiles, mainly woolstuffs for carpets and upholstery. Stuck in are hundreds of actual dyed samples, with instructions for achieving the colours, their fastness and suitablility for the specific use of the fabric.
