Gabo's sculptures are frequently made from translucent plastic, phosphor bronze or glass; the shape is usually a swooping arc, strung with taut wire or string, like a harp, that forms a delicate open-sided cage for space. Their construction has been likened to architecture, their humming strings to music, their balance to mathematics...
...bouncing off targets, is focused on a semitransparent screen at the front end of an extremely sensitive electron tube. The screen is photoemissive-it gives off electrons when struck by the faintest light. These photoelectrons are then speeded up by high electrical charges so that when they hit a phosphor (luminescent) screen in the tube, they make a much brighter image. The process is repeated three times, until it produces a picture thousands of times brighter than the starlit target viewed by an unaided...
...sixth U.S. maker to manufacture its own color tubes when its new $12 million factory is finished. National Video, the supplier of Motorola's 23-inch color tubes, is spending $4,000,000 to double its capacity. Sylvania has developed a new color tube with a rare earth phosphor that makes it 40% brighter than others on the market. Last week Zenith introduced its new 25-inch rectangular color tube, which shows more of the transmitted picture, and Philco began pilot production of 21-inch color tubes...
...roaring for days and finally set the roof on fire. Now when a fire breaks out in a sculptor's studio, it is more likely to be caused by an unwatched oxyacetylene torch. The material may still be bronze, but there is an added glitter of stainless steel, phosphor or chrome. The great difference is that Cellini produced in bronze a famous Perseus; today's sculptors too often end up with a glittering space divider or macabre wall hanging. Startling and even elegant as such modern objects can be (see color pages), they tend more to snag...
...others who start with an image, then shape materials to embody their vision. The richly decorative materials-first approach is handsomely demonstrated in one whole red-walled gallery at the museum's show. There Italian-born Harry Bertoia's Wall Piece ($750) melds steel, bronze and phosphor into an elegant decoration. Bertoia makes no claim for it beyond stating he considers it "a few squares arranged in a quiet way around a stand." His Flower ($900) proves he can do a welded screen in the round. It also happens to be more personal: "I had just returned from...
