What is "bucchero"

n. A type of dark grey Etruscan terracotta pottery

Bucchero is a class of ceramics produced in central Italy by the region's pre-Roman Etruscan population. This Italian word is derived from the Latin poculum, a drinking-vessel, perhaps through the Spanish búcaro, or the Portuguese púcaro.

Regarded as the "national" pottery of ancient Etruria, bucchero ware is distinguished by its black fabric as well as glossy, black surface achieved through the unique " reduction" method in which it was fired. After the leather-hard green ware was arranged in the kiln and the fire started, the vent holes were closed, thus reducing the supply of oxygen required in a normal kiln firing. In the smoke-filled atmosphere of the kiln, the oxygen-starved flames drew oxygen molecules from the iron oxide of the pottery. This process caused the fabric of the clay to change color from its natural red to black. Thus, in contrast to the black- glazed Campanian ware of the Greek colonists in southern Italy, the lustrous, shiny, black surface of many bucchero pots was achieved by diligent burnishing (polishing,) or, occasionally, through the application of a thin slip (clay emulsion).
