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.
