A manual of dyeing with the dyestuffs of the Cassella color company, New York ..
A trade manual published in New York in 1911 by the Cassella Color Company, a dyestuff maker, to instruct dyers in using its dyes. The four photographs show the experimental dye-house in four sections, from laboratory-scale drying through large-scale vat dyeing and piece-dyeing machines. For a designer, they offer a plain record of early twentieth-century industrial interiors, with rows of round vats, pipework, and workers at machines on a bright factory floor.
