摘要： A process for making a foundry mold for use in metal casting, which comprises the steps of heating and drying mold sand composed of refractory particles and a water-soluble binding agent, charging a cavity formed in a mold pattern with the mold sand under dried condition, during the charging step, moisture being kept on the peripheral surface of the mold to be made, and heating the whole pattern of which the cavity has been filled completely with the mold sand to thereby cure mainly the peripheral surface of the mold.
