695. _Scarlet Ink._--Dissolve vermilion in a solution of gum-arabic.
696. _Red Ink._--Boil one ounce of Brazil wood in half-a-pint of water for a quarter of an hour; add to the decoction three drachms of gum-arabic, and an ounce of alum.
697. _Green Ink._--Verdigris, two ounces; cream of tartar, one ounce; water, half a pint; boil till reduced to one half, and filter.
698. _Excellent Writing Ink._--Boil eight ounces of galls in coarse powder, and four ounces of logwood in thin chips, in twelve pints of rain water, for one hour: strain the liquor, and add four ounces of green copperas, three ounces of powdered gum-arabic, one ounce of blue vitriol, and one ounce of rock candy, powdered; stir the mixture until the whole be dissolved, then let it subside twenty-four hours; decant it very steadily, and put it into stone bottles for use.
A clove kept in it will prevent it from becoming mouldy.
699. _Black Ink._--To make one gallon, take of pounded blue nutgalls one pound; copperas, six ounces; gum common, four ounces; soft water, one gallon. Dissolve the gum separately by the fire, and add, after it has boiled a quarter of an hour. Let the ink be boiled over a slow fire three-quarters of an hour.
700. _To make Ink._--To four ounces of bruised galls, allow two of copperas and two of gum-arabic; put the galls into a large bottle, with three pints of rain water; and, in three or four days, dissolve the gum in hot water, and add it with the copperas. Shake the bottle frequently for some days. A few cloves may be put into the bottle, to prevent the ink from moulding.
701. _Ink Powder._--Take five ounces of the cleanest nutgalls, bruise them, and sift the powder very fine; then add one ounce of white copperas, two ounces of Roman vitriol, gum-arabic, half an ounce; pound and sift them very fine. An ounce of this powder will make a pint of very black ink.
702. _To prevent Ink from moulding._--Half-a-dozen cloves, bruised with gum-arabic, are to be put into the bottle. If a very fine ink is wanted, white wine, or vinegar and water, should be used, instead of water alone.
703. _To make Indian Ink._--Put six lighted wicks into a dish of oil; hang an iron or tin concave cover over it, so as to receive all the smoke; when there is a sufficient quantity of soot settled to the cover, then take it off gently with a feather upon a sheet of paper, and mix it up with gum-tragacanth to a proper consistence.
