The ubiquitous Pyrex measuring cup in your kitchen made its debut in 1925, but the first Pyrex dish hit the market 10 years earlier, after a Corning scientist brought home a sawed-off industrial-glass jar to his wife, who baked a sponge cake in it. At least that's Corning's story, and they're sticking to it at a Pyrex centennial celebration at the Corning Museum of Glass, starting June 6. Pyrex is still around — and still "hot," as Associated Press reporter Michael Hill notes in the video below — but Corning hasn't made the iconic heat-resistant glass since it sold its consumer products division in 1998; it's now made by World Kitchen, based in Rosemont, Illinois. For more Pyrex facts, watch below or read AP's fact sheet. —Peter Weber
