Casting practices have been recently adopted in many schools from elementally school to upper secondary school. In these practices bronze casting were tried using CO_2 process mold that becomes hard in a short time after CO_2 gas blowing. But bronze products of yayoi period like as mirror, bell-shaped vessel were supposed to be made by means of clay mold. Therefore in this study we tried porcelain clay as clay mold for bronze casting. As a result porcelain clay mold was found to be suitable for bronze casting, paying special attention to shrinkages of mold at drying and baking.
