90. To cleanse Bottles.—To cleanse bottles with bad smells, put into them pieces of blotting or brown paper, and fill up with water; shake the bottles, and leave them for a day or two, when, if they be not sweetened, repeat the process, and rinse with pure water.
91. To restore the Lustre of Glasses tarnished by Age or Accident.—Strew on them powdered fuller's-earth, carefully cleared from sand, &c., and rub them carefully with a linen cloth. Oxide of tin (putty) would perhaps be better.
92. To clean China.—China is best cleaned, when very dirty, with finely-powdered fuller's-earth and warm water; afterwards rinsing it well in clean water. A little clean soft soap may be added to the water instead of fuller's-earth. The same plan is recommended for cleaning glass.
93. To clean Alabaster.—Remove any spots of grease with spirit of turpentine: then dip the article in water for about ten minutes, rub it with a painter's brush and let it dry; finish by rubbing it with a soft brush dipped into dry and fine plaster of Paris.
94. To bleach Ivory.—Ivory that has become discolored, may be brought to a pure whiteness by exposing it to the sun under glasses; having first brushed the ivory with pumice-stone, burnt and made into a paste with water. To conceal the cracks in antique ivory, brush out the dust with warm water and soap, and then place the ivory under glass. It should be daily exposed to the sun, and turned from time to time, that it may become equally bleached.
