Imerys Kiln Furniture

Earthenware is a porous and robust material. It’s not translucent and can be white or coloured.

Although body formulations vary tremendously between countries, and even between individual makers, a generic composition is 25% ball clay, 28% kaolin, 32% quartz, and 15% feldspar. Due to its higher porosity than stoneware or porcelain, earthenware needs to be fully glazed to be watertight.

Biscuit firing (Temperature : 1 050 – 1 150°C):

Products - Solutions	Compositions	Key Features
Pressed Batts (Extruded possible)	Cordierite	• Low thermal mass • High flatness • Very long life-time • Very precise and stable geometric dimensions • High resistance to bending at high temperature

Glost firing (Temperature: 1 000 - 1 100 °C):

As firing temperature is considerably lower than for stoneware or porcelain, Cordierite is the preferred material for earthenware glost firing.
