Inks for Hand Stamps As an excipient for oily inks, a mixture of castor oil and crude oleic acid, in parts varying according to the coloring material used, is admirable. The following are examples: Black: - Oil soluble nigrosin and crude oleic acid in equal parts. Add 7 to 8 parts of castor oil. Red: - Oil soluble aniline red, 2 parts; crude oleic acid, 3 parts; castor oil, from 30 to 60 parts, according to the intensity of color desired. Red: - Dissolve ¼ ounce of carmine in 2 ounces strong water of ammonia, and add 1 drachm of glycerine and ¾ ounce dextrin. Blue: - Rub 1 ounce Prussian blue with enough water to make a perfectly smooth paste: then add 1 ounce dextrin, in corporate it well, and finally add sufficient water to bring it to the proper consistency. Blue: - Oil soluble aniline blue, 1 part; crude oleic acid, 2 parts; castor oil, 30 to 32 parts. |
