Shantung Lung-shan Culture (ca. 2600-2000 BC), Neolithic period
Height: 24 cm, rim diameter: 11 cm, base diameter: 6 cm
During the Lung-shan Culture, the technique of using a potting wheel to produce ceramic objects was developed. Vessels with very thin walls could be made, and even carved with openwork patterns, in what became known as "egg-shell pottery". In the kiln, the adding of charcoal at the very end or closing the air intake would create a flux of carbon that creates black pottery.
