...tree, filled it with birds imported from the U.S. There Artist Doughty spends months studying her birds, sketching poses, shaping preliminary models. Then, in a single intense day of disciplined haste, a final image is made. Because porcelain products shrink to one-third model-size when fired in the kiln (the temperature goes as high as 1,200° F.), they must be painstakingly pre-sized. Because thin, delicate clay shapes (such as flower petals) can stand less heat than heavier parts, porcelain models as variable as the Doughty birds are baked by a complicated shifting of heavy and light...
Miss Doughty has a kiln of her own, but her birds are now kiln-fired at Britain's Royal Worcester Porcelain Co., where reproductions are made in limited editions. So highly does Royal Worcester rate Miss Doughty's work that it has originated a new mark, a gold W, to stamp them with...
...brilliant show on Broadway. If Bizet's Carmen and the all-Negro Carmen Jones live, artistically, on different sides of the railroad tracks, they nevertheless represent the shortest distance between one exciting kind of job and another. Drastic changes have been made. Carmen has been retired in a kiln, not warmed over in an oven. There is no capricious tinkering for tinkering's sake. Respectfulness everywhere chaperones audacity...
...Ford, dolomite is powdered, calcined (burned in a kiln) and mixed with ferrosilicon-an electric-furnace product of silicon and iron long used in steelmaking. The mixture is pressed into briquettes and charged into furnaces. When these are heated under vacuum, magnesium vapor is given off, and it crystallizes as on removable steel sleeves...
...make sponge iron, ore is not smelted. It is mixed with pulverized coal (natural gas can also be used) and coke, then fed to a large rotary kiln. When the kiln is heated to 1,800°F., the powdered coal first robs the ore (iron oxide) of its oxygen, then turns into gas, leaving fairly pure iron granules which have a spongy texture. This stuff can then be fed to the steel furnaces...
