Corning Glass Works and Pyrex

From Wikipedia:  Pyrex was created in 1915 when chemists at Corning Glass Works invented a new kind of borosilicate glass that could withstand extreme temperature fluctuations.  Soon after, popular over-to-table-to-refrigerator household kitchenware was introduced.  The continued popularity of Pyrex over the years saw the creation of nested and Cinderella mixing bowls, casseroles, divided servers, refrigerator sets, carafes, and dinnerware (to name a few) in bright colors and lively patterns.
