258. To cement Broken China or Glass.—Beat lime to the finest powder, and sift it through fine muslin; then tie some into a thin muslin; put on the edges of the broken china some white of egg; dust some lime quickly on the same, and unite them exactly.
259. Chinese method of mending China.—Take a piece of flint-glass, beat it to a fine powder, and grind it well with the white of an egg, and it joins china without riveting, so that no art can break it in the same place. You are to observe, that the composition is to be ground extremely fine.
260. Improved Corks for preserving Wine or Chemical Liquors.—Melt together two parts of white wax and one part of beef suet; dip your corks in this mixture, and immediately dry them in a stove upon an iron plate; repeat this operation twice, and the corks thus prepared will preserve any liquor well without imparting any ill-flavor thereto.
261. Bottle Cement.—Common red and black sealing-wax, of each half-a-pound; bees'-wax, quarter of an ounce. Melt them in an earthen pipkin or brass kettle. The former is preferable, because the cement may be kept in it, and again melted whenever it is wanted for use. When the mixture begins to froth, and seems likely to boil over, stir with a tallow candle, which will settle the froth. As soon as the whole is melted, it is ready for use.
262. Bottle Cement.—Melt in an iron ladle some rosin, and a quarter as much bees'-wax; add a little Venetian red, stir with a piece of candle, and, when smoothly melted, dip in the top of the bottles, so as completely to cover them. In making this cement, be careful not to leave it a moment while it is on the fire.
