Bamboo pottery tool from Krăngọ village

To scrape the inside of the pots, the potters use rings made of a thin slice of bamboo with both ends tied together, called a kơnur (top). The kơnur are now imitated in metal (bottom), They are used when the pots are too dry. The potter usually still use the bamboo tool afterwards as the metal ones make the surface “ugly”. Because of the many inclusion in the clay, they are used really fast. The newest ones (right), more sharpe, are use to thin the walls of the pots, while the ones that are already used, with blunt edges (left), are used in the preforming of the bottom. The action of scraping is called "kor".
