...Satire. The two dozen sculptors and painters exhibiting in the goldsmiths' 800-piece show have skirted this difficulty. They have ignored diamonds, sapphires and rubies, and in their place found quartz, jade and pebbles to set in hammered or cast gold, silver or bronze. Painter Jean Dubuffet, for example, sets a lump of coal in a ring as an act of intentional satire...
...rays are created by a quartz crystal, which converts electrical energy from an oscillator into mechanical vibrations in the air at a frequency of 1,000,000 cycles per second. A cone-shaped concentrator mechanically coupled to the crystal intensifies these vibrations and produces a sharply defined beam. The surgeon removes a small portion of the bone behind the ear, acoustically irradiates the exposed canal with the gun's waves. Much as a soprano's high note can shatter a wineglass, the beams shot from the gun are supposed to shake the diseased cell structure and destroy...
...slightly more energy than the others because their electrons are spinning in a different way. When the atom stream shoots through a system of magnets, the low-energy atoms in it are deflected sideways while the high-energy ones converge, pass through a small hole in a 6-in. quartz bulb. The bulb is lined with paraffin which does not affect the atom's energy state as metal or bare quartz would, so the atoms bounce about inside for as much as a whole second, hitting the walls 10,000 times without losing their extra energy...
...ideas freely from their conquerors, they added their own craftsmanlike touches, which had been passed down through 2,000 years of Egyptian civilization. Artisans eschewed the hard-tipped metal tools used by foreign sculptors, pounded away at the quarry rock with stone cutting tools, polished the finished work with quartz sand. Details such as the echeloned curls, sinuous eyebrows, and almond-shaped eyes of the Girl with a Late Period Bob were painstakingly sculpted. So perfect was the technique of these artisans that even today no modern steel cutting tool can achieve the same sable smoothness on hard stone...
