Ink, Indelible Marking.—One and a half drachms of nitrate of silver, one ounce of distilled water, half an ounce of strong mucilage of gum arabic, three-quarters of a drachm of liquid ammonia. Mix the above in a clean glass bottle, cork tightly, and keep in a dark place till dissolved, and ever afterwards. Directions for use: Shake the bottle, then dip a clean quill pen in the ink, and write or draw what you require on the article; immediately hold it close to the fire (without scorching), or pass a hot iron over it, and it will become a deep and indelible black, indestructible by either time or acids of any description.
Ink, Indestructible.—On many occasions it is of importance to employ an ink indestructible by any process, that will not equally destroy the material on which it is applied. For black ink, twenty-five grains of copal, in powder, are to be dissolved in two hundred grains of oil of lavender, by the assistance of a gentle heat, and are then to be mixed with two and a half grains of lampblack and half a grain of indigo. This ink is particularly useful for labelling phials, &c., containing chemical, substances of a corrosive nature.
Ink for Marking Linen with Type.—Dissolve one part of asphaltum in four parts of oil of turpentine, and lamp-black or black-lead, in fine powder, in sufficient quantity to render of proper consistency to print with type.
Ink Powder for Immediate Use.—Reduce to powder ten ounces of gall-nuts, three ounces of green copperas, two ounces each of powdered alum and gum arabic. Put a little of this mixture into white wine, and it will be fit for immediate use.
Ink Stains.—The moment the ink is spilled, take a little milk, and saturate the stain, soak it up with a rag, and apply a little more milk, rubbing it well in. In a few minutes the ink will be completely removed.
Red Ink.—Take of the raspings of Brazil wood, quarter of a pound, and infuse them two or three days in colorless vinegar. Boil the infusion one hour and a half over a gentle fire, and afterward filter it while hot, through paper laid in an earthenware cullender. Put it again over the fire, and dissolve in it first half an ounce of gum arabic, and afterward of alum and white sugar each half an ounce. Care should be taken that the Brazil wood be not adulterated with the Braziletto or campeachy wood.
Transfer Ink.—Mastic in tears, four ounces; shellac, six oz.; Venice turpentine, half an ounce; melt together; add wax, half a pound; tallow, three ounces. When dissolved, further add hard tallow soap (in shavings), three ounces; and when the whole is combined, add lampblack, two ounces. Mix well, cool a little, and then pour it into molds. This ink is rubbed down with a little water in a cup or saucer, in the same way as water-color cakes. In winter, the operation should be performed near the fire.
Indian Glues.—Take one pound of the best glue, the stronger the better, boil it and strain it very clear; boil also four ounces of isinglass; put the mixture into a double glue pot, add half a pound of brown sugar, and boil the whole until it gets thick; then pour it into thin plates or molds, and when cold you may cut and dry them in small pieces for the pocket. The glue is used by merely holding it over steam, or wetting it with the mouth. This is a most useful and convenient article, being much stronger than common glue. It is sold under the name of Indian glue, but is much less expensive in making, and is applicable to all kinds of small fractures, etc.; answers well on the hardest woods, and cements china, etc., though, of course, it will not resist the action of hot water. For parchment and paper, in lieu of gum or paste, it will be found equally convenient.
Japanese Cement.—Intimately mix the best powdered rice with a little cold water, then gradually add boiling water until a proper consistence is acquired, being particularly careful to keep it well stirred all the time; lastly, it must be boiled for one minute in a clean saucepan or earthern pipkin. This glue is beautifully white and almost transparent, for which reason it is well adapted for fancy paper work, which requires a strong and colorless cement.
Liquid Blacking.—Mix a quarter of a pound of ivory-black, six gills of vinegar, a tablespoonful of sweet oil, and two large spoonfuls of molasses. Stir the whole well together, and it will then be fit for use.
