After the Late Tang Dynasty: The material gradually evolved from bare pottery to glazed pottery, which makes the appearance of the Chiwen more beautiful and durable.
Song and Liao and Jin Dynasties: Due to the expansion of the scale of the building, some large-scale Chiwen’s need to be made by multiple pieces of colored glass splicing, such as the Great Hall of Huayan Temple on Datong, Shanxi.
Ming and Qing period: At this time, the Chiwen more than use solid colored glass material, this material not only beautiful, and fireproof performance, not easy to cause fire.
The selection and use of these materials not only reflect the technical level and aesthetic concept of the ancient craftsmen, but also reflect the social and economic conditions and cultural background of different historical periods.

Design and Molding: First of all, craftsmen need to draw the design of the design of a Chiwen. These patterns often contain complex ornamentation, which represents profound cultural significance. During the moulding stage, the craftsman will convert the design pattern into a specific mold shape for the subsequent casting process.
Fabrication of copper Chiwen (Shibi) by Gens Metal
Material selection: select suitable copper material. Common materials include copper, brass, bronze, etc., which are widely used for architectural decoration due to their good ductility and corrosion resistance.
Engraving and machining: The use of carving and other traditional manual techniques to carve the mold meticulously. In this step, craftsmen will use the ductility of the copper material, for ornamental carving and carving. For example, the shadow carving is a primitive technique, also known as the shadow carving, through which the outline and surface texture of the pattern are carved, the lines are simple and clear.

forming: after the carving is completed, the casting process is performed (if material is brass or bronze); The copper plate is also used for cutting, extruding and welding to create the required shape of the Chiwen, which requires a steel or aluminium alloy frame as a structural support inside the copper material.
Finishing and polishing: After forming, the finished product needs to be trimmed and polished to remove excess copper and ensure that the details of the decoration are clearly visible. This step may also involve manual refinement to achieve the final design.
Installation: After the above steps to obtain the Chiwen, need to be carefully installed. Normally, the owls are placed at the ends of the roof ridges of a building to provide decoration and ward off evil spirits, and to fit perfectly with the roof structure without damaging its strength.
