Glass has a co-efficient of expansion and contraction. When glass is cooled too quickly below 950º F tremendous strain is created. Like many materials, glass expands as it heats and shrinks as it cools. When glass is allowed to cool quickly it cools unevenly, which in turn creates strain (not stress).
