Factors governing paint consistency / by Henry Green.
A 1923 technical booklet by Henry Green, published by the New Jersey Zinc Company, covering paint pigments and zinc and how they govern paint consistency. The first picture is a hand-drawn field of dashes with scattered hatched blob shapes, and the second pairs a photographed white crumbly mass with a smooth white ellipse on dark grey, showing pigment particle forms and textures a designer could borrow for organic patterns and tonal contrast studies.
