Some physical properties of paint, varnish and nitro-cellulose lacquer films / by Harley A. Nelson and George W. Rundle.
A 1930 technical monograph by Harley A. Nelson and George W. Rundle, published by the New Jersey Zinc Company, reporting laboratory tests of paint, varnish and nitro-cellulose lacquer films for industry readers. Its pictures are plain engineering line graphs plotting elongation in per cent against load in grams per square centimetre, with curves labelled by humidity conditions and film type, offering a designer little beyond the look of technical charts with grids, labelled axes and sparse curved lines.
