Εξάλλου, there are techniques such as inlay, dot emerald, and enamel. There are more than ten kinds of materials used for inlay: white jade, ζαφείρι, jasper, τοπάζι, νεφρίτης, τουρκουάζ, malachite, αχάτης λίθος, κεχριμπάρι, κρύσταλλο, μαργαριτάρι, ελεφαντόδοντο, και τα λοιπά. The process of Diancui: make the basic mold of the silver jewelry, stick the silver wire to the silver tire according to the pattern requirements, and weld it firmly, and then repeat the degreasing process such as burning, pickling and brushing, and then apply the color Toba (usually blue and green) is filled with glue into the pattern formed by the silver wire frame, and finally polished and polished. The dotted silver ornaments are often gilded. Craftsmen know that blue and gold are the most brilliant.
The main tools for making silverware: silver melting furnace, wind box, hand hammer, hand pliers, multi-functional set of cutting tools, worktable, vise, spray gun, welding gun, blowtorch, crucible, measuring tool, steel tape measure, πλατεία, και τα λοιπά. Εξάλλου, there are various types of cast copper molds, multi-function files, iron scissors, compasses, angle rulers, long-handled wire-like copper brushes, flat-end anvils, και τα λοιπά. The main raw and auxiliary materials for the manufacture of silverware: waste silver products, silver noodles, red copper, soldering pot, clay, coke, saponified lime, white rock, borax, sawn wood surface, bad water, dry soil, και τα λοιπά.
Silver jewelry processing table gold technology division
1. 鎏 (镏) gold craft: a method of decorating objects with gold. Apply the gold dissolved in mercury to the surface of the utensil with a brush, dry it, bake it with charcoal fire, and then calender it with agate. The whole process generally needs to be repeated three times.
2. Dipping gold process: Dip the object in the gold solution that has been dissolved in mercury (mercury) or three water (a mixture of one part of concentrated nitric acid and three parts of concentrated hydrochloric acid), and then take it out. This is the easiest way to watch gold.
3. Lacquer process: paint the surface of the utensil with paint made of metal powder.
4. Gold plating process: using electrolysis or other chemical methods to make gold adhere to the surface of metal or other objects to form a thin layer of gold. 5. The process of sticking gold: stick gold foil on the utensils.
6. Gold-clad technology: beat gold or silver into thin slices, wrap it on the carcass, and then compact it with a hammer to make the handmade silverware. 1. Casting and engraving. The casting method comes from the bronze craft, Tang Dynasty In the future, the use of gold and silver jewelry will become less and less. For engraving, use various shapes of steel chisel, and engrave the pattern on the surface or back of the blank. There are several types of engraving techniques, such as male engraving, shadow engraving, and flat and hollow type. Among the Ming Dynasty handed down pieces of Yunnan silver jewellery, a considerable part is made by a combination of casting and engraving.
Δεύτερος, hammered and engraved are the main ones, and engraved and engraved are supplemented by Yunnan silver jewelry. Some are chiseled with hammers from forming to decoration, some are formed by welding after hammering, and some are decorated with silver rings and silver chains after hammering. Some silver jewellery shapes are vertical carvings, round carvings, and they are also hammered and then welded. The details are carved and engraved.
3. Filigree craftsmanship plus inlay, dotted emerald or enamel weaving, piled, τσαλακωμένος, and welded with silver wire to make various flat or three-dimensional patterns and ornaments, collectively called filigree crafts. It can be made into a larger volume jewelry with less silver material, and it is very delicate and exquisite. Inlaying, gilding, emerald or enamel are often used at the same time. There were many jewelry of this type in Yunnan silver jewelry in the Qing Dynasty.
Silverware processing Silverware production process:
1. Ασήμι: first weigh out the weight of the silver material used with a scale, smash the large piece of silver material into a crucible and place it on the furnace to melt. When the blast furnace becomes incandescent, the silver begins to melt, and the crucible is used to cast the copper mold with a long handle clamp.
2. Forging: When the silver material is not cold, start forging and shape the silver billet as desired.
3. Τομή: lay out the silver piece according to the designed silverware artwork. The silver piece should be slightly larger than the artwork. If it is a special shape, it should be unfolded into a flat surface for processing.
4. The rough processing is preliminary to punch out the big bumps of silver jewelry
5. Make a lead holder: The role of the lead holder is to hold and fix the silver sheet to be processed for further production. Put the rough-processed silver sheet upside down in the sand box, pour the molten lead into it, and cool it down. Αλλοτε, rosin was used as support
6. Finishing: This process includes hammering, χαρακτική, και χαρακτική. It is the most critical place in the whole process. Many silversmiths in Yunnan call this process “carving.” The tools used for carving are a small hammer and several chisels. The chisel heads are pointed, γύρω, επίπεδα, crescent-shaped, petal-shaped, και τα λοιπά., which can be selected according to needs. When processing, the left hand holds the hammer, like a painter’s pen, the heart and hands correspond to each other, and groups of vivid and vivid patterns are carved out. The key to the pros and cons of silver jewellery is at this time. The subtle details of the carving show the craftsman’s meticulousness and accuracy.
7. Welding: For silver ornaments that need to be welded, hang solder on the interface, put it in the fire and heat it up for a while. The ingredients of the flux, the temperature of the furnace and the length of heating time are closely related to the quality of welding.
8. Θύλακα: After repeated beating and medium temperature, the surface of silverware will become black or stained with impurities. Επομένως, pickling is required. The pickling solution is made of nitric acid and sulfuric acid, and the silver jewelry is rinsed in the pickling solution. Take it out quickly and rinse with water. It is very important to control the time of this process. The time of immersion in the pickling solution is too short and the impurities cannot be washed clean. Will affect the luster of silver jewelry. If the immersion time is too long, the pickling solution will corrode the silver jewelry and also destroy the color and finish. After rinsing and drying, be sure to choose a sunny day, the clearer the weather, the more beautiful the color of the silver ornaments after drying.
