History.
The history of making the terracotta works in Pondicherry is not definitely established though archaeological excavations at Arikamedu (which had ancient maritime links with Rome during the first century AD) have unearthed fine quality terracotta toys which are considered of finer quality than the type made by the Satavahanas.
This art work is particularly traced to Villianur village and its neighboring areas, as an ancestral legacy of over 20 generations of the community known as "Kulalar". During the French rule of Pondicherry this art form received a fillip.
Process of manufacture.
The basic materials used in handcrafting of the terracotta works are green clay, "thennal" and fine sand locally called "savudu". Several types of tools made of bamboo are used in handcrafting the art forms. In the first step of processing clay is sifted to remove all stones. Then a mixture of 20 percent of clay, 40 percent of "thennal" and 40 percent of fine sand is made. After kneading thoroughly the mixture is cured by allowing it to dry for some time. The prepared mixture is then used in small quantities to make the products such as toys, statues, etc., in different forms. For making statues moulds are used for the body parts while the rest of the figures are ornamented with motifs by hand. The completed art work is then allowed to dry for 12 hours after which it is ready for sale. 
To enhance the life of statues the craft work is subjected to the process of firing for about 30 minutes with Poda husk, powdered wood and "Saanam." After firing, the craft work is covered with sand and allowed to cool. 
Some of the products made are of gods, goddesses, divinities, animals forms, wall hangings and so forth. One of the tallest statues made is of a horse of height which can be detached and reassembled. The smallest size product measures about an inch, particularly of Ganesha.
A specialty of Villianur terracotta, which is not possible with other terracotta works, is that they can be made to a height of and moulded to any thickness. 
Quality control is exercised by a committee consisting of 2 Master Craftsman of Villianur Terracotta Works, a representative from Pondicherry Crafts Foundation, and Associate Professors from National Institute of Fashion Technology (NIFT), Chennai.
