Why do the thick glass tumblers crack on pouring hot liquid into them?

Answer

Glass is a bad conductor of heat. Therefore, when hot liquid is poured into thick tumbler, inner side of glass expands while outer side remains the same.
Therefore, due to unequal expansions of inner and outer sides, the tumbler cracks.
