Why does glass crack when heated then cooled?

Answer.

When allowed to cool on its own, the glass cools down evenly on all sides;inside and out.

When cooled fast, e.g.

by running cold water on it, the glass cools down unevenly, and therefor cause the glass to crack because the inside contracts while the outside remains expanded.
