Terracotta, a type of earthenware, is a clay-based unglazed or glazed ceramic,where the fired body is porous. Terracotta is the term normally used for sculpture made in earthenware, and also for various utilitarian uses including vessels (notably flower pots), water and waste water pipes, bricks, and surface embellishment in building construction, The term is also used to refer to the natural, brownish orange color, of most terracotta, which varies considerably.
In archaeology and art history, “terracotta” is often used to describe objects such as figurines not made on a potter’s wheel. Vessels and other objects that are or might be made on a wheel from the same material are called earthenware pottery; the choice of term depends on the type of object rather than the material or firing technique. Unglazed pieces,and those made for building construction and industry, are also more likely to be referred to as terracotta, whereas tableware and other vessels are called earthenware (though sometimes terracotta if unglazed), or by a more precise term such as faience.
