Manhattan importers were six months, behind with their orders. Porcelain fanciers, in an invisible but impatient queue, waited last week for their ceramic birds, which they bought as fast as they could be imported from Britain. The superbly color-glazed, life-sized birds, perched in natural flower and branch settings, cost from $250 to $475 a pair...
...late great Charles Montagu (Travels in Arabia Deserta) Doughty (TIME, Sept. 6). Shy, 51 and a spinster, Ceramist Doughty lives in Cornwall, England. Some ten years ago, she was inspired by John James Audubon's Birds of America, is now England's only fashioner in porcelain of the birds...
Artist Doughty's porcelain birds are as meticulously realistic as Audubon's. But she does not depend on him for her avian observations. For that purpose she had a big wire cage constructed around an old apple 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...
...discoverer is a young Selas physical chemist named John M. Walker. He has astonished engineers with some of his demonstrations: e.g., he pours a mixture of kerosene and water into a tube; the liquid comes out rapidly through the pores of two closed-end porcelain cylinders which are the outlets of the vessel; out of one comes pure water, out of the other, pure kerosene...
Walker tested his theory on fine porcelain membranes with pores as small as a 25,000th of an inch. It worked. By treating porcelain so that it could be wetted only by a specified liquid (e.g., coated with a special stearate, porcelain is wetted by kerosene but not by water), he found that up to a certain pressure the membrane was porous to that liquid but not to others...
