2. Haslam, W. 44–47.The Library Handbook of Genuine Trade Secrets and Instructions for Cleaning, Repairing and Restoring Old Manuscripts, Engravings and Books as practiced by the Experts.(Place and date of publication not known), A few interesting and alarming recipes for glue and paste making are given here:Gum, Elastic—Mix thoroughly in a wide mouthed bottle, one part salicylic acid, three parts soft soap, three parts glycerine, and twenty parts alcohol. Shake well together and add a mucilage already prepared consisting of about ninety-three parts gum arabic to 180 parts water (distilled, if available). (Is said to be an excellent adhesive and keeps well).Gum, to keep indefinitely—Dissolve one part gum arabic in one part water. Add a few drops of glycerine or chloroform, and pass through a muslin strainer.Gum, for Labels—This gum is similar to that used on postage stamps; as it can be brushed on the backs of labels, allowed to dry, and wetted when the labels are required for use. Soak three ounces of common glue in cold water overnight. Dissolve four ounces of gum arabic and the soaked glue. Stir thoroughly, and keep it well mixed.Paste, Durable—This is a paste which will keep good for twelve months or more if stored in a cool place, and-well covered. A small portion can be taken out when required for use, and simply softened with a little warm water. Dissolve a teaspoonful of alum in a quart of warm water. When cold, stir in enough flour to make a thick cream, breaking up all lumps. Stir in a few drops of oil of cloves to keep it sweet, and as much powdered resin as will lie on a sixpence. Place over the fire a saucepan containing a teacupful of boiling water: into this pour the flour mixture, stirring all the time. Boil and stir for a few minutes, until it thickens. Pour into an earthenware vessel, and when cool, cover up.Another—Dissolve one ounce of alum in a quart of warm water, allow to cool, and add as much flour as will make a thick cream. Stir in half a teaspoonful of powdered resin, and two or three cloves. Boil and stir constantly, until it thickens.Paste, Liquid—This paste is excellent for wrappers, labels, fine bookbinders' work, and general office use. It dries with a gloss, and does not turn mouldy and remains liquid in the bottle. Dissolve one pound of gum arabic and three ounces of sugar in one pound of water (nearly one pint). When quite dissolved, add a quarter of an ounce of nitric acid, and bring to a boil. Mix with starch paste, about half-and-half and bottle.Another—The following recipe is also reliable. In a pint and a half of water place one pound of potato starch and one ounce of pure nitric acid. Stand the mixture in a warm place, and stir frequently for about forty-eight hours. Place the jar in a saucepan of water, and boil until thick mush is formed. If too thick add a little more water, and filter through a cloth before bottling.Paste, Strong Adhesive for Paper Cloth or Leather—Soak four parts of glue in fifteen parts of cold water for eighteen hours. Heat till transparent, and, without stirring, add sixty-five parts boiling water. In another vessel, prepare a thin liquid, composed of thirty parts starch and 200 parts cold water, and place this over the lire in a roomy saucepan. Pour the boiling glue mixture into the starch, and boil for a few minutes, stirring vigorously all the time. The parts are by measure, not weight
