A lab mishap at Owens-Illinois Glass Company resulted in fine glass fibers, which were later adapted into a steam-blown manufacturing process in 1932. The company would form a partnership with Corning Glass Works in 1935 and would first introduce it as a revolutionary consumer and industrial material at the 1939 New York World's Fair.
