Most of the examined artifacts were detected to bear remains of starch grain,which provided important information for understanding their function. In particular,processed and undamaged starch grains were discovered on rare-seen pottery rollers,which,therefore,must have been used for processing plants. The remains of cooked starch grain on the grooved basins suggest that this type of vessel may be a processing tool or container of plant food,which reflects the multiple use of ancient pottery.展开更多
