With a comparison to Stoneware, Earthenware is fired at a lower temperature. Earthenware is also more porous than stoneware and needs to be glazed or it will absorb water. Earthenware fires up to 1200 degrees Celsius. Pit-fired earthenware was developed between about 29,000 and 25,000 years ago while Stoneware was developed about 5,000 years ago. Earthenware is opaque after it is fired and is more porous The clay for making earthenware has greater plasticity and is fine-grained. Earthenware has greater absorption at usually 5 to 8 percent. It should be glazed to make it more watertight. Earthenware is usually terracotta in color and is an easy clay to work with.
