I want to introduct something about Lagerstroemia indica plant. Lagerstroemia indica
A terra cotta sculpture of Hanuman in India. The reddish color is due to iron oxide in the source clay. Clays with low iron content can result in paler colors on firing, ranging from white to yellow.
Terra cotta designs outside the Kantaji Temple.
Glazed building decoration at the Forbidden City, Beijing, China.
The Etruscan "Sarcophagus of the Spouses", at the National Etruscan Museum.
The Bell Edison Telephone Building, Birmingham, England.
The Natural History Museum in London has an ornate terracotta facade typical of high Victorian architecture. The carvings represent the contents of the Museum.

"Terracotta" redirects here. Terra cotta, Terracotta or Terra-cotta (Italian: "baked earth", from the Latin terra cocta) is a clay-based unglazed ceramic. Its uses include vessels, water waste water pipes and surface embellishment in building construction, along with sculpture such as the Terracotta Army and Greek terracotta figurines. The term is also used to refer to items made out of this material and to its natural, brownish orange color. In archaeology and art history, "terracotta" is often used of objects not made on a potter"s wheel, such as figurines, where objects made on the wheel from the same material, possibly even by the same person, are called pottery; the choice of term depending on the type of object rather than the material. Plain unglazed pottery is often also called terracotta.
Production and properties
An appropriate refined clay is partially dried and cast, molded, or hand worked into the desired shape. After further thorough drying it is placed in a kiln, or atop combustible material in a pit, and then fired. After pit firing the hot ware is covered with sand to cool, and after kiln firing the kiln is slowly cooled. When unglazed, the material will not be waterproof, but it is suitable for in-ground use to carry pressurized water (an archaic use), for garden ware, and sculpture or building decoration in tropical environments, and for oil containers, oil lamps, or ovens. Most other uses such as for table ware, sanitary piping, or building decoration in freezing environments require that the material be glazed. Terra cotta, if uncracked, will ring if lightly struck, but not as brightly as will ware fired at higher temperature, which is called stoneware. The fired material is weak compared to stoneware.
Some types of terra cotta are created from clay that includes recycled terra cotta ("grog").
The unglazed color after firing can vary widely, but most common clays contain enough iron to cause an orange, orangish red, or brownish orange color, with this range including various colors described as "terra cotta". Other colors include yellow, gray, and pink.
History
Terra cotta has been used throughout history for sculpture and pottery, as well as bricks and roof shingles. In ancient times, the first clay sculptures were dried (baked) in the sun after being formed. Later, they were placed in the ashes of open hearths to harden, and finally kilns were used, similar to those used for pottery today. However only after firing to high temperature would it be classed as a ceramic material. The most famous terra cotta statues are those of the Terracotta Warriors in China.
Uses
Significant uses of terra cotta have included Emperor Qin Shi Huang"s Terracotta Army of China, built in 210209 BC. Mass producers of mold-cast and fired terra cotta figurines were also the ancient Greeks of Tanagra. French sculptor Albert-Ernest Carrier-Belleuse made many terra cotta pieces, but possibly the most famous is The Abduction of Hippodameia depicting the Greek mythological scene of a centaur kidnapping Hippodameia on her wedding day. American architect Louis Sullivan is well-known for his elaborate glazed terra cotta ornamentation, designs that would have been impossible to execute in any other medium. Terra cotta and tile were used extensively in the town buildings of Victorian Birmingham, England.
Precolonial West African sculpture also made extensive use of terra cotta. The regions most recognized for producing terra cotta art in this part of the world include the Nok culture of central and north-central Nigeria, the Ife/Benin cultural axis in western and southern Nigeria (also noted for its exceptionally naturalistic sculpture), and the Igbo culture area of eastern Nigeria, which excelled in terra cotta pottery. These related, but separate, traditions also gave birth to elaborate schools of bronze and brass...(and so on) To get More information , you can visit some products about , .
