An explosion such as the H-bomb would blow them skyward, heating them past 1,710° centigrade, at which temperature silica melts. But they would harden again at the lower temperatures of the atmosphere and, being feather light, would float on the wind across the Pacific -to strike windshields...
Climax' miners, who must tunnel through Colorado's Bartlett Mountain for the ore, call it "molly bedamned," and until World War I no one had much use for the metal.

"Probably," he says, "all play a role in the development of arteriosclerosis."
