Section I Metal Hollowing, Sawing, and Welding Processes
In metal craft production, as long as the design concept is clever, interesting works can be created using the most basic techniques. Hollowing, sawing, and welding processes are the foundation of metal crafts, and we can use the most basic saw bows, saw blades, and drill bits to make jewelry.
1. Air-Dried Pomegranate Fruit — Case Study of Hollow Enameling Production
1. Design transfer: After designing the pattern, we need to transfer it onto the metal; for flatter metal pieces, we generally use tracing paper to draw or directly draw the pattern and then stick it onto the metal piece with paste.
2. Use a chisel and hammer to locate the drilling position.
3. Use a hanging grinder drill burs to make the hole.
4. Hollow out: Insert the jigsaw blade through the hole and install it, then cut out the shape from the inside.
5. After annealing, use a wooden stick to shape the hollowed part into an arch.
6. Fill in the enamel.
7. Please place it in the enameling furnace and fire it for about 1 minute in an environment of approximately 750℃.
8. Different colors of enamel can be added and fired multiple times according to the color of the pomegranate.
9. The air-dried pomegranate is now complete.
2. Diamond-shaped Pearl Ring and Earring-making Case
(1) Preparation work
1. Materials needed: 925 silver sheets, silver wire, baroque pearls.
2. Cutting the board, size is 5 cm x 1.4 cm.
3. Annealing the silver piece.
(2) Welding the ring
1. Use flat-nose pliers to symmetrically bend the metal sheet at both ends 90°Bend.
2. Zegnij oba końce w zamknięte półkole.
3. Coat the joints with borax.
4. Cut a suitable amount of soldering flux and place it on the welded part.
5. Welding with a welding gun to melt the solder.
(3) Integer-segmented metal ring
1. Shape it with a ring stick and wooden mallet after welding is complete.
2. Use a caliper to evenly divide and position the metal ring.
3. Cut the metal ring evenly to prepare for making a pair of symmetrical earrings.
(4) Making claw setting pearls
1. Measure the corresponding U-shaped structure length of the claw setting base according to the size of the diamond-shaped pearl; a 0.8 mm diameter metal wire can be used to make the U-shaped structure, and a 1 mm diameter metal wire can be used to make a ring.
2. Use a round file to grind a slot below the bottom of a u shape for welding.

3. Grind grooves at the average 4-point position on the inner side of the ring with a round file for welding.
(5) Spawanie
1. First, weld the two U-shaped metal wires.
2. Then, weld the ring onto the welded-shaped metal.
3. Finally, the finished claw setting will be welded to the ring, and the ear pin will be welded to the back side of the ring.
(6) Polishing and setting
1. The metal setting is pickled, polished, and securely installed with diamond-shaped pearls.
2. Completed.
Section II Metal Texturing Techniques
In addition to polishing, there are many other texture-processing techniques for metal surfaces, which are very suitable for exploration and learning and can be applied to jewelry creation. When processing the texture of a metal surface, it is important to remember to anneal the metal first, making it more flexible and easier to work with.
1. Hammering Texture
In metalworking, using different hammers, chisels, and other tools can create a variety of textures.
Filling the interior of metal vessels with lead
Choose the appropriate chisel
Hammering the uneven texture with a hammer and chisel
Directly hammering the hammered texture
Changing the shape of the metal can with a hammer
Trimming the edge of the metal bowl
2. Imprinting Texture
Select relatively suitable items in softness, hardness, and size, and use them in conjunction with a rolling mill to create interesting textures. Copper mesh, textured paper, leaves, lace, and other items are all high-quality materials for creating imprint textures.
If multiple overlapping textures are needed, multiple pressings are required, and the metal must be annealed again before each operation. This way, the metal has good flexibility, is not easily broken, and has a better imprint effect.
The metal must be annealed before each imprint operation.

After making the metal parts, soak them in a copper aging solution, controlling the time according to the instructions of the aging solution you are using. After naturally air-drying, use a hanging grinder and fine sandpaper to polish the surface, leaving the natural aged black in the textured grooves. In contrast, the metal surface presents a silky luster effect after polishing.
Section III Metal Wrinkling Technique
The wrinkling technique uses the high temperature of flames to melt the surface of the metal and then creates jewelry with a wrinkled texture. The wrinkled effect of this technique is non-reproducible; even with rich experience, one cannot produce identical textures, making the works created by this technique more unique and accidental.
Xiebai, wrinkling technique jewelry series, Flowing Golden Years, brass, Baroque pearls
1. Wrinkling Process Principles
The wrinkling process is closely related to the metals’ melting point, the flame spraying angle, and the cooling time. Although the wrinkling process only creates textures on the surface of the metal, during heating, the inner layer melts first, and the surface forms wrinkles and textures as the internal metal flows. For example, a 925 silver piece is made of 92.5% silver and 7.5% copper. During the wrinkling heating process, copper is continuously oxidized first, and then silver begins to oxidize, resulting in two melting points for the metal, which provides good conditions for wrinkling. The lower the purity of the silver alloy, the easier it is to form a wrinkled effect. Similarly, copper alloys can also be textured through the wrinkling process.
