...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...
Sunlight TV Tube. Conventional TV pictures tend to fade out when the light in the room gets too bright. This is because the glowing substance (phosphor) on the face of the picture tube is a reflective powder. In sunlight or other strong light, the reflection gets brighter than the picture and washes the picture...
Last week the Naval Research Laboratory told about its new system of depositing the glowing phosphor as a transparent film by vacuum evaporation. The purpose of the project was to improve airplane instruments, but the transparent phosphor can be used for TV too. The picture will form as usual when the set is turned on, but light coming from the room will be reflected very weakly. Most of it will pass into the interior of the tube and be lost. So the picture will stay sharp and clear with full daylight shining on the tube...
...energy beta particles (electrons). Other atomic batteries have attempted to turn beta particles directly into electric current, but they have often run into trouble because the particles damage the current-yielding parts of the battery. The Kidde-Elgin battery sidesteps this difficulty by mixing the promethium 147 with a phosphor (light-giving substance) and enclosing the mixture in transparent plastic. Electrons from the Pm-147 make the phosphor glow, and its light is turned into electricity by a photoelectric surface of silicon on each side of the plastic wafer. No electrons escape from the plastic, and so the silicon...
