250. To make Lip Glue, for joining Paper, Silk, or thin Leather, &c.—Take of isinglass and parchment glues, of each one ounce; sugar-candy and gum-tragacanth, each two drachms; add to them an ounce of water, and boil the whole together till the mixture, when cold, is of the consistence of glue; then form the same into small rolls, or any other figure that may be most convenient, and it will be fit for use.
This glue may be wet with the tongue, and rubbed on the edges of the paper, silk, or leather, that are to be joined; and on being laid together, and suffered to dry, they will be united as firmly as any other part of the substance.
251. Liquid Glue.—Pour naphtha upon shellac until of a creamy consistence, and keep it closely corked. This glue will unite iron, wood, glass, &c. It is water-proof, and dries quickly.
252. Glue to hold against Fire or Water.—Mix a handful of quick-lime in four ounces of linseed-oil, boil them to a good thickness, then spread it on tin plates in the shade, and it will become exceedingly hard; but may be easily dissolved over the fire, as glue.
253. To mend China.—Mix together equal parts of fine glue, white of eggs, and white of lead, and with it anoint the edges of the article to be mended; press them together, and when hard and dry scrape off as much of the cement as sticks about the joint. The juice of garlic is another good cement, and leaves no mark where it has been used.
