Engineers foresee even more esoteric uses. They have already designed a hover kiln, in which pottery is suspended over a moving conveyor belt by the hot gases used to bake it. And they are attempting to perfect a hover bed for badly burned patients who would actually lie on a thin film of air, thus avoiding painful contact with the bed sheets and allowing healing on all sides...
Before Wedgwood, those Englishmen who could not eat off gold plates ate off pewter and wooden trenchers. Josiah changed all that. At age nine, he had started "throwing," or molding clay, at his brother's pottery, opened his own kiln 20 years later, and plunged into the relentless experimentation that marked him as one of the most liberal and scientific minds of the Age of Enlightenment. This is the 200th anniversary of the year when his cream-colored earthenware so impressed Queen Charlotte I that she made Wedgwood her court potter and ordered that pearly pottery be called Queen...

...Reader Spring's foundry, where Sculptor Jacques Lipchitz' statues are cast, burns out wax in the traditional way by placing the double-thick clay mold in a kiln fired to 1,200°F. Some of the wax escapes through a small hole in the cast, but most of it is absorbed by the porous clay...
...broke smelting down into two processes, v. one in the blast furnace. The first, a horizontal, slowly rotating, gas-fired kiln, removes 55% of such impurities as oxygen and sulphur from ores of such low grade that blast furnaces cannot handle them, conditions them for the second step. This is a Udy-designed electric smelting furnace that finishes the job. The slag from the electric furnace can be put through a series of similar furnaces to draw off other metals such as chrome, copper, zinc and manganese. Thus, for the first time, a smeltery can work iron ore over with...
