(1674) Painting With Coal-Oil and Petroleum.

Manufacturer and Builder 10, 1876

—Neither coal-oil nor petroleum is much used in the North and East for painting. Crude petroleum will not dry; the only kinds that can be used are the distilled petroleums, some of which will dry; but they are much inferior to linseed-oil paints or turpentine. They do not give a brown color to the wood, except when a brown coloring material has been put in. The coloring effect of the oils alone is very slight, except when they are tarry; for instance, from coal-tar something of this kind is made which produces a brown color and dries quickly.
