Painters' colours, oils, and varnishes : a practical manual
A practical technical manual on painters' colours, oils and varnishes, written by George Henry Hurst and published in London by Charles Griffin & Company in 1906 for painters and decorators. Its pictures are line diagrams of industrial equipment: a sectioned multi-tray drying or stove chamber, a mechanical grinding mill with a hopper, a lead-chamber process with tanks and piping, and a brick kiln with arched furnace doors. A designer might take from them the clean, schematic line style of early twentieth-century technical drawing, with hatched cross-sections and labelled apparatus.
