Ten Techniques for Manufacturing Gold and Silverware

　　Watch in three minutes Gold and silverware The ten manufacturing processes!

　　1. Lost-wax casting

　　Gold or silver is melted into a liquid and then cast into objects using molds. During the Shang and Zhou dynasties, when bronze casting had reached a highly sophisticated level, this method became second nature to artisans, enabling them to produce exquisitely detailed products.

　　Judging from the shape, size, and cross-section of the gold amulets unearthed from the Shang Dynasty tomb at Liujiagou in Beijing, they appear to have been cast. This represents China’s earliest known instance of gold casting, demonstrating that China had mastered the art of casting gold and silver artifacts more than 3,000 years ago.

　　2. Hammering

　　One of the ancient traditional fine goldsmithing and silversmithing techniques is still in use today. Hammering This technique takes advantage of gold and silver’s excellent malleability: gold and silver ingots are hammered into thin sheets, which can then be shaped into various forms as needed. While this process uses relatively little material, its drawback is that the resulting objects tend to deform easily.

　　3. Welding

　　Welding is commonly used in a variety of metalworking techniques. First, the two parts to be welded together are temporarily bonded using an adhesive. Next, a “flux” (which can be made of gold, silver, or other metals such as copper and tin) is applied onto the adhesive. After the flux is heated and then allowed to cool, the two parts become firmly joined together.

　　When welding with copper-doped flux, prolonged corrosion can cause green rust stains to appear on the welded components. For example, during the Tang Dynasty, an octagonal silver belt cup adorned with Yue script motifs exhibited green rust along the edges of the textual patterns and at the weld seams on the handle.

　　4. Riveting

　　The purpose of riveting is the same as that of welding: both methods are used to join attachments to the main body. However, unlike welding, riveting involves making small holes in the two parts to be joined and then inserting a rivet (typically made of the same material as the main body of the device). The ends of the rivet are then hammered flat, pressing them tightly against the surface of the device, thereby achieving a secure bond. Riveting is commonly used at points where buttons, hinges, handles, loop handles, latches, suspension beams, and body panels are attached to the vehicle body.

　　5. Chiseling

　　Also known as carving, this is an advanced processing technique applied after an object has been shaped. On a flat surface, patterns can be carved, and the gold and silver surrounding the patterns can be “tapered” to create a relief effect. Generally speaking, patterns carved with sharp chisels tend to be more delicate, while those carved with blunter chisels appear rounder. By using several chisels of varying sharpness, it’s possible to carve colorful patterns.

　　6. Compile accumulation

　　Flat weaving involves using gold and silver threads as fine as hair, which are then coiled and welded together to create various patterns—similar to the “filigree” technique mentioned later. In contrast, three-dimensional weaving requires first crafting various figures, birds, animals, or vessels from carbon. Gold and silver threads are then wound around these carbon molds. Next, the molds are filled with gold and silver threads and placed in a fire, where the carbon core is burned away, leaving behind exquisite three-dimensional gold and silver jewelry.

　　7. Cloisonné

　　Primarily used for decorating gold and silver objects, this technique involves cutting the beaten gold and silver into thin strips and gradually twisting them into fine threads. Another method for producing gold and silver threads is called “drawing,” in which the gold or silver is slowly squeezed through a conical die, allowing it to be drawn out as fine threads. Coarser threads can also be directly hammered. Wrapping these gold and silver threads around a specific pattern and then soldering them onto the surface of an object constitutes an exquisite form of decoration.

　　8. Gilt

　　Products made using the gilding technique appeared as early as the Pre-Qin period, yet written records of the gilding process did not emerge until the Northern and Southern Dynasties. The method involves mixing pure gold with mercury in a specific ratio to create an “amalgam” (commonly known as “gold paste”). This amalgam is evenly spread over the surface of the vessel, after which the piece is heated over a fire. As the mercury heats up, it evaporates, leaving behind only a thin layer of gold that adheres tightly to the surface of the object—without any visible traces of deliberate ornamentation. As a result, the object acquires an exquisite and beautiful appearance.

　　9. Inlaid gold

　　In ancient times, embedding metal wires into objects was known as “cuo.” The cuo-jin-bai-gong technique involves inlaying gold threads or gold sheets onto cast bronze artifacts to create intricate and ornate patterns or inscriptions. The surface of the artifact is then polished, revealing the beautifully crafted gold and silver wire patterns and inscriptions.

　　10. Welding appendages

　　The raw material used in the soldering technique is quite special—gold beads. How are these gold beads made? Gold is cut into small pieces, then heated or ground between two plates to form beads. Another method is called “fritting” (also known as “melting beads”): molten gold is dripped into lukewarm water, where it solidifies into gold beads of varying sizes. The resulting gold beads can be either soldered or adhered onto surfaces. Gold and silverware The surface of the vessel has high practical value.
