Classic Terracotta - Not baked

http://www.classicterracotta.co.uk/ Terracotta ('baked earth') is baked clay that has not been glazed. The word is applied also to the reddish-brown colour considered most typical of the material, although it occurs in various other colours. Terracotta is a traditional material for containers and remains popular because the colour and texture of the material is sympathetic to plants.
