The Manufacturer and Builder 12, 1877
The best kind of common printer's ink will do. To make it, boil 1½ gallons of old and clear lin-seed oil to the consistency of a thick varnish, add while hot 6 pounds of powdered resin, 1 3/4 pounds of dry brown soap shavings, 2½ ounces of indigo, 2½ ounces of Prussian blue, and 5 pounds of the best lampblack; stir these all in well, let it stand a week, and then grind it.
