Pyroceram is a ceramic-glass invention that was all the rage when it was discovered in a lab in upstate New York. Pyroceram was invented by Stanley Donald Stookey in the 1953. Stookey discovered Pyroceram, a white glass-ceramic material capable of withstanding a thermal shock or a sudden temperature change of 840 degrees F. The discovery happened for the scientist by accident while he was working with photosensitive glass. Stookey placed a piece of white glass ceramic material into a furnace planning. He was going to heat it to 600 degrees. He checked the furnace and the temperature gauge was stuck at 900 degrees F and the piece in the furnace had turned a milky white color. Upon removing the piece from the furnace using tongs, the piece fell to the floor. Expecting it to break, the piece did not shatter. This was a major breakthrough. The material which came to be known as Pyroceram was later used in the ballistic missile program for heat resistant nose cones and was marketed widely as the ovenware that we now all know as CorningWare.
