Shell baking is a very important process in casting , after de-wax and we usually lay the shell one night , and in the second morning , we take the shell to baking furnace ,usually laid in side by side , so that can put more shell .usually the temperature is between 870 °C and 1095 °C ,  remove any moisture and residual wax , the shell can be taken from it , the shell now is much hard and strength after baking , later our people will cast the shell at the night . it was used  to burn the coal for baking process , however we now burn the gas , so that can reduce the pollution and make the product quality better.
