The filled pit is then set on fire and carefully tended until most of the inner fuel has been consumed. At around 1,100 °C (2,010 °F) the maximum temperatures are moderate compared to other techniques used for pottery, [4] and the pottery produced counts as earthenware. After cooling, pots are removed and cleaned; there may be patterns and ...
