Terracotta, also known as terra cotta or terra-cotta (ˌtɛrraˈkɔtta; baked earth; ), is a term used in some contexts for earthenware. That is to say it is a clay-based unglazed or glazed non-vitreous ceramic, fired at relatively low temperatures.
Usage and definitions of the term varies, such as:
In art, pottery, applied art, craft, construction and architecture, "terracotta" is a term often used for red-coloured earthenware sculptures or functional articles such as flower pots, water and waste water pipes, tableware, roofing tiles and surface embellishment on buildings. In such applications the material is also called terracotta.
In archaeology and art history, "terracotta" is often used to describe objects such as figurines and loom weights not made on a potter's wheel, with vessels and other objects made on a wheel from the same material referred to as earthenware; the choice of term depends on the type of object rather than the material or shaping technique.
Terracotta is also used to refer to the natural brownish orange color of most terracotta.
Glazed architectural terracotta and its unglazed version as exterior surfaces for buildings were used in East Asia for some centuries before becoming popular in the West in the 19th century. Architectural terracotta can also refer to decorated ceramic elements such as antefixes and revetments, which made a large contribution to the appearance of temples and other buildings in the classical architecture of Europe, as well as in the Ancient Near East.
This article covers the senses of terracotta as a medium in sculpture, as in the Terracotta Army and Greek terracotta figurines, and architectural decoration. East Asian and European sculpture in porcelain is not covered.

Prior to firing terracotta clays can be easily shaped. Articles can be formed by both an "additive" technique, adding portions of clay to the growing pieces, or a "subtractive" one, carving into a solid lump with a knife or similar tool.

In classical antiquity, the Hellenistic period covers the time in Mediterranean history after Classical Greece, between the death of Alexander the Great in 323 BC to the death of Cleopatra VII (30 BC) followed by the emergence of the Roman Empire, as signified by the Battle of Actium in 31 BC and the conquest of Ptolemaic Egypt the following year. The Ancient Greek word Hellas (Ἑλλάς, Hellás) was gradually recognized as the name for Greece, from which the word Hellenistic was derived.
Relief is a sculptural method in which the sculpted pieces remain attached to a solid background of the same material. The term relief is from the Latin verb relevo, to raise. To create a sculpture in relief is to give the impression that the sculpted material has been raised above the background plane. When a relief is carved into a flat surface of stone (relief sculpture) or wood (relief carving), the field is actually lowered, leaving the unsculpted areas seeming higher.
Pottery is the process and the products of forming vessels and other objects with clay and other raw materials, which are fired at high temperatures to give them a hard and durable form. The place where such wares are made by a potter is also called a pottery (plural potteries). The definition of pottery, used by the ASTM International, is "all fired ceramic wares that contain clay when formed, except technical, structural, and refractory products".
In this paper, a theoretical and experimental investigation of the effect of temperature on water retention phenomena in deformable soils is presented. A general law expressing the change in suction with water content, temperature and void ratio is propose ...
Glazed envelopes can cause significant thermal energy gains or losses. The installation of a novel design of Complex Fenestration Systems (CFS), such as embedded mirrors, could significantly contribute to reduce the energy consumption. In order to determin ...
