In order to trace the cause of cracking phenomenon of clay body during steady heating in a saturated atmosphere, some experiments were conducted with some clays which were treated with different methods.
The main results are summarized as follows:
(1) The actual range over which cracking takes place is a property of clay.
(2) Drying treatment of a raw clay reduces the critical temperature at which cracking commerces.
(3) The unequal condition or included air in clay body do not effect cracking in a saturated atmosphere.
(4) The critical temperature at which cracking commerces is influenced by introducing salt solutions, and the alkali solution increases that temperature.
(5) There is a definite relationship between the critical temperature and the moisturecontent of the clay.
