1889For black ink:
Take of balsam of copaiba (pure), 9 ounces; lamp black, 3 ounces; indigo and Prussian blue, of each half an ounce; Indian red, 3/4 ounce; yellow soap (dry), 3 ounces; grind the mixture to an impalpable smoothness by means of a stone and muller. Canada balsam may be substituted for balsam of copaiba where the smell of the latter is objectionable, but the ink then dries very quickly.
The red inks are similarly made by using such pigments as carmine, lakes, vermilion, chrome yellow, red lead, orange red, Indian red and Venetian red.
