After the creation of a wax model and its accommodation inside a muffle (50) the wax is removed by melting in a pre-heating device. Ceramic pellets and a die (S) are inserted and all parts heated in the pressing device. After its removal the muffle (50) is provided with several projections at the bottom, facilitating a free flow of warm air in the resulting space (25) during the main pressing process, ensuring an even heating of the object and preventing the soft ceramic substance from cooling down quicker in some areas.
