  1. Soak 4 oz. best glue and 1 oz. isinglass in water until soft. Pour off the super fluous water, and add 1 oz. brown sugar. Melt the whole together with a gentle heat, and allow it to evaporate until quite thick. Pour into a flat- bottomed dish that is quite cold; if placed on ice, so much the better, as it will prevent the glue sticking to it. When solid, cut into cakes.
  2. Glue, 5 oz.; sugar, 1 oz.; dissolved in water, boiled down, poured into moulds, or on to a slab of slate or marble, and dried.
  3. Isinglass and parchment glue, each 1 oz.; sugar candy and gum tragacanth, each 2 dr.; add to them 1 oz. of water; boil the whole till the mixture appears, when cold, of the consistence of glue. Then form it into small rolls for use. This glue, wetted with the tongue and rubbed on the edges of the paper, silk, etc., to be cemented, will, on their being laid together and suffered to dry, unite them as firmly as any other part of the surface.
  4. Put a pinch of shredded gelatine into a wide-mouthed bottle; put on it a very little water, and about ¼ of glacial acetic acid; insert a well-fitting cork. If the right quantity of water and acid be used, the gelatine will swell up into worm-like pieces, quite elastic, but at the same time, firm enough to be handled comfortably. The acid will make the preparation keep indefinitely. When required for use, take a small fragment of the swelled gelatine, and warm the end of it in the flame of a match or candle; it will immediately "run" into a fine clear glue, which can be applied at once direct to the article to be mended. The thing is done in half a minute, and is, moreover, done well, for the gelatine so treated makes the very best and finest glue that can be had. This plan might be modified by dissolving a trace of chrome-alum in the water used for moistening the gelatine, in which case, no doubt, the glue would become insoluble when set.
  5. Take ¼ lb. of very best Scotch glue, melt it in a clean glue-pot. When quite dissolved, pour off the clear part into another glue-pot, add ½ pint boiling water, well mix. Then add 2 oz. best moist sugar; well mix the whole together, at the same time keeping it quite hot. It may then be cast into moulds, or poured gently on a marble or stone, or slab. When nearly set, cut into strips for use. It should be kept in boxes with a little powdered sugar or starch. This glue will be found both cheap and effective. It is much stronger than paste or gum.
