Viscous clay is thrown into a mould.
The jiggerer brings the clay from the bottom of the mould, up the inside of the mould with his hand. He then brings down the shoe into the mould to press the clay into the negative image of the mould. Once the piece is sufficiently dry, it is removed form the mould for further drying and displays a positive image. Ram dies, jiggering and casting molds are made here. All products, prior to glazing, must be dry.
