Fig.3 (IMAGE) Kanazawa University Caption Incisions on the back surfaces of tile ends and patterns on the front surfaces. Artisans firmly joined tile ends to imbrices through a process which left obvious traces on the back surfaces of the tile ends. Tile ends with simple petals mostly contain thin, radially oriented scratched incisions (Fig. 3.1), while those with compound petals usually contain wide, triangular-shaped curved incisions (Fig. 3.2). The correlation between pattern and processing technique identifies two production systems at the Ximing Temple workshop.
