In the foundry practice, it is generally percieved to get a good surfaced casting, if the hydrostatic pressure of molten metal and the internal pressure in the sand core are balanced each other on the surface of the core after teeming melt. To see this relation, the auther tried to determine the internal pressure in the small different sized cores included some kinds of core binder and some other combustible substances, like Kordeck, soybeanoil, coal powder and ricebran, after teeming melt by means of an experiment and a theoretical calculation. And then obtained experimentally an interesting relation between the hydrostatic pressure of molen metal and the internal pressure in the core.
