Waste-wax Process
Making statuary, figures, etc., by melting out a wax model of the object, which has been previously encased in loam or composition, and filling the space with molten metal. See CIRE PERDUE; STATUE-FOUNDING. Water is a compound of 8 parts by weight of oxygen with one of hydrogen; by bulk it is 1 of oxygen to 2 of hydrogen, and is present in nature in three forms--solid, liquid, and gaseous. It is transparent, tasteless, and inodorous. It evaporates at all temperatures, boils at 212 deg., and freezes at 32 deg. At 60 deg. a cubic inch of pure water weighs 252.45 grains--exactly 815 times the weight of an equal bulk of air. The American standard gallon weighs 58,970 grains of pure distilled water at the maximum density of 484. The weight of an imperial gallon is 70,000 grains, or 10 pounds. A cubic foot of water is taken at 1000 ounces, and 62.5 pounds for convenience in reckoning; but the actual weight is 998.068 ounces, or 62.37925 pounds avoirdupois.
Water expands 1/1124 of its bulk in freezing.
The height of a column of water at 60 deg., equivalent to the pressure of 1 pound per square inch, is 2.30 feet, and the height of atmosphere is 33.94 feet. The number of cubic feet in a ton of water is 35.84, and a cubic foot of sea-water weighs 64.31 pounds. See HYDROGEN.
