One method of making rubber stamp ink is to dissolve aniline in hot glycerine, straining while hot. A rubber stamp ink that will not smear or blur burnished surfaces is made by dissolving 180gr. of violet aniline crystals in 2oz. of boiling distilled water. Addone teaspoonfulof glycerine and half a teaspoonfulof treacle. Dissolve about 1 dr. of aniline violet in 5oz. of methylated spirit and 5oz. of glycerine. Black aniline does not answer so well, and is usually mixed with a small quantity of violet or green aniline. Black ink for rubber stamps may be made by grinding vegetable black or Lampblack in glycerine and then thinning with a little alcohol. Dissolve 3 parts of aniline colour in in parts of distilled water, 10 parts of acetic acid, 10 parts of alcohol, and 70 parts of glycerine. The ingredients above mentioned form the bulk of stamp inks, and though there are many recipes not given here, they merely differ as regards the proportions.
