Zinc oxide and its application to paint / by L.H. Trott.
A 1928 technical booklet by L. H. Trott, published by the New Jersey Zinc Company, explaining zinc oxide as a paint pigment for industrial and building trades. Its pictures are plain photographs and line diagrams: a grid of painted panels, a dark wedge with a pale oval, a stippled-and-hatched figure, and a magnified micrograph of irregular granules, offering a designer useful examples of mid-century technical imagery built on clear tonal contrast and simple geometry.
