Stoneware pottery is produced from clay that
is fired to a dense, hard, vitreous state at a temperature of over 2300
degrees Fahrenheit. When stoneware is fired in kilns that burn gas flames
come in contact with the ware. Reducing or increasing the amount of oxygen
entering the kiln allows the artist to control the atmosphere of the kiln
thus having a wide range of glaze effects. Stoneware is used for making
functional, durable pots. It may be gray, buff or brown after the final
firing. Stoneware pottery is food safe and will hold water.
