Ceramic substrate for catalytic convertors—In response to the Clean Air Act of 1970, engineers Bagley and Lachman and geologist Lewis, all of Corning Glass, created a ceramic substrate for use in automotive technology that converts 95% of exhaust pollutants into water vapor and carbon dioxide. Thirty years later, their invention is credited with reducing automotive pollutants by more than 3 billion tons worldwide. Ceramic substrate technology is now used by every automotive manufacturer in the world. (2002)
