IMCO | Stoneware 1-C

Stoneware 1-C fires to a sandstone color in oxidation and a brown in reduction. Stoneware 1-C contains a fine silica sand to make an excellent smooth textured wheel clay which will produce vitreous stoneware pottery within the temperature range of an electric kiln. Stoneware 1-C will give the appearance of a cone 10 reduction clay body when fired to cone 5 in oxidation. This body is made of local clays averaging just 25 miles from the pits to our pug mill. This clay was originally designed as a cone 6 body but as the clay has changed in the pits Stoneware 1-C now vitrifies at cone 8 (this change occurred around 2015)

Dry Shrink | 7%

Fired Shrink | 11.8% at cone 6

Absorption | 8% at cone 6
