Firing pottery in Yang Tao village : Taking pots out of the fire for post-firing process

When the pots are red, Yo Khoanh takes a stick and takes out one of the pots by the opening. She directly burries it in rice husk for the post firing. This will give it its black colour. The potters also state that this process helps to evenly cook the pottery. Once they have an even black color, the pots are taken out of the husk. At the same time, CdF asks her some question. She cannot use anything else than the rice husk, otherwise the pots would not be evenly black.
