The Sanage kilns were the major provincial kilns which lay in Seto city in the north, Toyota in the east, Ohbu in the south and Nagoya in the west, and they produced Sue ware and woodenash glazed pottery using single chamber kilns called Anagama. The Kanechika No. 1 kiln which was restored to the original state was one of the Sanage kilns, and it is 6 meters long, 1.5 meters wide and 1 meter high. It was built in a half-buried kiln with the top covered with earth. The following is concerned with the experiment of firing using the kanechika No. 1 kiln restored. Experimental results are summarized as follows : (1) The experiment of firing continued for about 60 hours. Consequently, maximum temperature was 1345℃, and then the difference with the minimum in the kiln was about 180℃. (2) According to the results of the gas analyzer the atmosphere in the kiln was very changeable at high temperature and besides was large in the difference owing to the places. But, through the firing it was possible to controll the atmosphere in the kiln. (3) About 600 faggots of akamatsu (Japanese red pine) were used for the experiment of firing. (4) As akamatsu contains a low percentage of ash, wodden-ash glaze was thin. (5) Most of the potteries in the kiln could be sintered.
