Philosophy of protective paint
Philosophy of Protective Paint is a 1907 trade handbook issued by the Joseph Dixon Crucible Company, a American graphite and paint maker, for builders and paint users wanting practical guidance on protecting surfaces. The pictures are plain black-and-white line diagrams showing cross-sections of paint layers over a hatched base, a stacked block with dashed grain lines, and a small tailpiece of an oil lamp beside books and wavy smoke. A designer could borrow their simple technical diagram style, with hatching and stippling used to separate layers and materials.
