Muromati and Edo Period Roof Tile Production

1)我研究了中世纪的屋顶瓦片，并将其分为八个阶段。有第一阶段（1180年至1210年），第二阶段（1210 - 1260）第三阶段（1260年至1300年），第四阶段（1300年至1333年），第五阶段（1333 - 1380）、第六阶段（1380 - 1430）、第七阶段（1430 - 1490）和第八阶段（1490 - 1575）。中世纪的屋瓦生产技术在个别阶段比古代的屋瓦生产技术更为明确。在中世纪的日本，有三种屋顶瓦生产系统。第一个系统是大和型。第二种制度是京都式的。最后一个系统是大坂类型。这三种类型的系统对日本中世纪的屋瓦生产有很大的影响。2）我研究了按时间顺序排列的第一代现代屋瓦，并将其划分为五个阶段。大佐城的屋顶瓦片是从坂井、姬路、京都、大和等地搬来的。

1) I studied chronological medieval rooftiles and divided eight stages. There are first stage (from 1180 to 1210), second stage (from 1210 to 1260), third stage (from 1260 to 1300), fourth stage (from 1300 to 1333), fifth stage (from 1333to 1380), sixth stage (from 1380 to 1430), seventh stage (from 1430 to 1490) and eighth stage (from 1490 to 1575). Medieval rooftile production technigues is more definite than ancient rooftile production technigues in individual stage. There are three rooftile production systems in medieval Japan. The first system is Yamato type. The second system is Kyoto type. The last system is Osaka type. These three type systems have great influence on Japanese medieval rooftile productions.2) I studied chronological first modern rooftiles and divided five stages. There are first stage (from 1575 to 1583), second stage (from 1583 to 1591), third stage (from 1591 to 1583), fourth stage (from 1607 to 1640), fifth stage (from 1640 to 1680).Roof tiles in Osasa Castle had been cazzied from Sakai, Himeji, Kyoto and Yamato.
