It begins with gathering necessary materials, then proceeds to prepare the mold by oiling a metal mold and mixing plaster of paris with water. The mixture is poured into the mold and left to solidify for at least a day. Finally, the metal mold is removed, revealing that the plaster has formed a detailed replica of the metal mold, demonstrating the process of mold making.
