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.
