Hydraulic pressure created by mould's suction within a ceramic cake formed out of slipwater has been simulated over its length and time on the analogy of a modified thermal Bow theory by diffusion-convection equation. The simulation results show that the pressure flow through the particulate medium of the cake, which also moves could lead to pressure accumulation with time in the layers close to the mould-cake interface and consequently develop internal stresses of tensile nature in the region. The results further indicate that the particulate cohesion of the cake would be disrupted at 0.1 cm position at 7.1 minutes as the resultant stress could exceed the green item's tensile strength.
