Pound pumice stone to a fine powder, and mix it with verjuice. Let it remain several hours, then dip in a perfectly clean sponge, and rub the marble with it till clean. Rinse it off with clear fresh water, and rub it dry with a clean linen cloth.
Beat the whites of eggs to a froth, then stir into them enough quicklime to make a consistent paste, then add iron file dust, to make a thick paste. The quicklime should be reduced to a fine powder before mixing it with the eggs. Fill the cracks in iron-ware with this cement, and let them remain several weeks before using them.
403. To loosen the Stopples of Decanters and Smelling Bottles that are wedged in tight.
Dip the end of a feather in oil, and rub it round the stopple, close to the mouth of the bottle; then put the bottle about a couple of feet from the fire, having the mouth towards it. The heat will cause the oil to run down between the stopple and mouth of the bottle. When warm, strike the bottle gently on both sides, with any light wooden instrument that you may happen to have. If the stopple cannot be taken out with the hand at the end of this process, repeat it, and you will finally succeed by persevering in it, however firmly it may be wedged in.
Dissolve a small lump of white sugar in a table-spoonful of rosewater, (common water will do, but is not as good.) Mix it with a couple of large spoonsful of sweet oil, a piece of spermaceti, of the size of half a butternut. Simmer the whole well together eight or ten minutes, then turn it into a small box.
Take of the oil of almonds two ounces, of spermaceti half an ounce, and white wax half an ounce. Put them in a close vessel, and set the vessel in a skillet of boiling water. When melted, beat the ingredients with rosewater until cold. Keep it in a tight box, or wide-mouthed bottle, corked up close.
