An introduction to the chemistry of paints
A 1910 technical primer by J. Newton Friend, published in London and New York, introducing the chemistry of paints for students and practitioners of the trade. The pictures are plain line diagrams of laboratory and works apparatus: a beaker over a burner with a thermometer, vessel cross-sections, a steam-jacketed stirred tank, and gas-washing flasks. A designer might take from them a spare, schematic line style suited to technical diagrams and labelled instructional figures.
