Plaster
This facial mold was among those discovered in 1980 in a region where their use in making religious statuary was common. Other molds for making ears and feet, as well as deer were also discovered. Semi-circular cylinders for applying patterns were also found. Most recovered pieces are made of plaster but some have clay added to increase their strength. A stone grinder was unearthed at the same time.
An urna rendered in the center of the forehead suggests the mold was used to produce Buddhas and other sacred figures in Buddhism.
