Since three has never been any incidence of having investigated kilns for firing soft stoneware in the proto-three kingdoms period so far, how they structured by reviewing historic literature and material was preconsidered in this study. It is presumed that after both Gimhae Daeseongdong-type and Sacheon Bonggyeri-type kilns for firing earthenware coexist early, through an internal alteration process which is mutually complex and momentous, the floor of plastic room has been flattened or slanted and expanded little by little into the closed-kiln structure. It seems that the structure of kilns for firing soft stoneware was a horizontal combustion type(水平燃燒式) and its plane shape was close to being rectangular in shape unlike that of kilns for firing stoneware found in Honam and Hoseo province in the period of (proto-) three kingdoms. On the other hand, it is likely that the horizontal combustion type structure of kilns for firing stoneware excavated in Samyong-ri, Jincheon preceded the vertical combustion type(垂直燃燒式)that of kilns for firing stonewere found in Sansu-ri. In addition, the term, monumeut for firing earthenware must be changed to kiln for firing earthenware and the terms of Pyeungyo(平窯) and Dyengyo(登窯) can be applied to kilns for firing tiles. Thus, it does not seem likely that the absolute equality that Wajil earthenware(soft stoneware) pottery is Pyeungyo and stoneware pottery is Dyeungyo is applied in all cases.
