Is there a natural way to make ancient flower buds?

Filament technology and flat filling technology Filament is a kind of fine gold technology which is made of metal wire by winding, pinching, filling and stacking.

Manufacturing process: melting, pressing and stretching the block metal into metal wire with required diameter; The wire is twisted (twisted) flat; Bend the coil into various patterns (clamp) with tweezers according to the pattern of the drawing; Close the pinched pattern and sprinkle welding powder on the fire to obtain various integral patterns (black tires); And black tires are acid-washed, sometimes silver-blue, burnt blue and gold-plated.

The ornaments made by this process have plump surface shapes and layered reliefs, mostly made of silver, which are sold abroad.

Mainly produced in Hebei, such as Beijing filigree mosaic field and Zhangjiakou arts and crafts factory.

The process of flat filling is similar to that of filigree, except that flat filling is to fill the silk circle into the plane of a frame, and the shape is fine and delicate, like a pattern outlined on paper. Products are mostly silver plates, silver bottles and other accessories for export. The main manufacturer is Chengdu Gold and Silver Jewelry Factory.

Filament and flat filling are called "oriental handicrafts", which have excellent myopia effect, but are easy to deform, collapse or weld. After long-term use, they are easy to hide evil and shelter evil, difficult to clean and the surface is not bright enough.

Lost wax casting is the main means of jewelry industry production at present, which is developed from ancient casting technology.

In the late Neolithic Age, more than 5,000 years ago, the lost wax casting process was widely used by ancient craftsmen in China to make bronzes.

At that time, according to the characteristics of plasticity and thermal volatilization of beeswax, craftsmen carved beeswax into a wax mold with the required shape, then wrapped clay outside the wax mold and reserved holes, dried it and baked it, so that the gas in the wax mold volatilized and the clay became a ceramic shell, and the required metal casting blank was obtained.

The principle of modern lost wax casting is no different from this, but it is more complicated and precise.

The general process of lost wax casting is as follows: molding the original mold into a silica gel mold, opening the mold and injecting wax to obtain a wax mold, planting wax trees in the wax mold, pouring high-temperature gypsum into a sleeve, vacuumizing the gypsum, naturally hardening, drying, casting, cooling the metal, frying the gypsum mold in cold water, taking out the casting, soaking it in acid, cleaning, cutting off the blank, rolling, then holding the mold, embedding and surface treatment.

The casting methods of lost wax casting include vacuum suction casting, centrifugal casting and vacuum centrifugal casting, which are the main means of mass production in jewelry manufacturing industry at present.

Gold wrapping: forging gold into gold leaves, and wrapping non-gold ornaments with gold leaves layer by layer.

The gold foil must be flattened and compacted, leaving no seams. This process is called gold plating.

Real gold-plated jewelry, the gold-plated layer is so thick that it can't be worn through for decades. This is the difference from gold-plated jewelry.

Gold plating: gold is made into extremely thin gold foil and pasted on the surface of jewelry, which is called gold plating process.

The gold plating process is not only used for jewelry making.

It is also commonly used in other buildings, flats, screens and handicrafts.

Gold plating: Gold will dissolve in the presence of mercury, resulting in "gold amalgam", which can flow freely.

When gold amalgam is heated, mercury will evaporate immediately and gold will remain.

The gold plating process is to use this principle to gold plate ornaments.

Gold plating technology is sometimes used in jewelry making, but it is most commonly used in religion and ancient buildings.

For example, Tibetan Buddhist buildings often use a large number of gold pieces on the roofs of temples, which become "golden roofs", which are more solemn and sacred against the blue sky.

In addition, the gold patterns of Chairman Mao Memorial Hall and Monument to People's Heroes are all made of gold.

However, this process is toxic when mercury volatilizes, so it is generally not suitable.

Gold tracing: Gold tracing refers to the process of drawing gold thread with a pen.

Painting gold powder is mixed with glue. After natural drying, the lines do not change color all the year round, and the picture looks golden.

In traditional jewelry making in China, gold tracing technology is often used.

In traditional arts and crafts, gold lacquer is often used in large murals, screens and hanging screens.

2.3 blue burning, cut flowers, gold carving and car flower technology

Blue-burning: Blue-burning process is one of the traditional jewelry processes in China. Because this "blue" can only be burned on the surface of silverware, it is also called "burning silver blue".

The silver-blue color has the transparency of watercolor painting and a unique taste.

The "blue" of burning blue is a block-like low-temperature glass formed after firing.

Blue firing process: mix the raw material powder of blue firing with water, shovel the blue material into the groove of silver tire with spatula, flatten the blue material, polish it, absorb water with absorbent cotton, and bake it in electric furnace. After the blue material melts and solidifies, it forms low-temperature colored glass and adheres to jewelry.

Cloisonne technology is similar to burning blue, but due to the different components of blue material, the "blue" eventually formed by cloisonne is not as transparent as watercolor as burning blue.

Cut flower: Cut flower is a metal deformation process in which different shapes of knives are struck with a hammer to form uneven, shiny or hairy lines and patterns on the surface of jewelry. Can be used to represent jewelry with different materials and textures.

Carving gold: also known as the flower-catching process, it has the same principle as the cut flower process, but the difference is that carving gold is to carve various lines and patterns on the metal surface with carving knives of different shapes, pushed by the palm of your hand, and the metal scraped off the surface flashes, making the carved lines free and smooth.

Carving gold requires superb manual skills, so the jewelry made in this way is even more precious.

Che Hua: Che Hua is a kind of jewelry processing technology that uses diamond milling cutters with different patterns to mill shiny stripes on the jewelry surface and form various patterns when rotating at high speed.

This process is often used in high hardness jewelry such as K-gold.

2.4 sandblasting, wire drawing and other processes

Sandblasting: Sandblasting is the process of using quartz sand to form a matte effect on the surface of jewelry under the action of high-pressure gas.

Wire drawing: Wire drawing is the process of pressing emery on the surface of jewelry to make directional movement, thus forming fine metal stripes (note: the wire drawing process here is different from wire drawing and tabletting in metalworking foundation).

Embossing: Embossing technology is often used for mass production of jewelry.

Because the pattern of jewelry has certain regularity, you can manually or mechanically process the required pattern on the steel template, then punch the pattern on the metal with a punching machine, and then weld it with other parts after cutting it out to become a complete jewelry.

Because the embossing process belongs to the plastic processing of metal surface, the processed jewelry surface is hard, wear-resistant, bright and durable, and it is not easy to be polished. However, due to the complexity of rigid molds and high-cost color changes, the ability of embossing process to adapt to the changing jewelry styles in the market needs to be improved.

Etching: the principle of engraving process is similar to the production of circuit boards. The treatment of positive drawing is to cover the metal parts to be preserved with acid-resistant paint and corrode the unnecessary metal parts with acid solution; The treatment of female lines is just the opposite of male lines.

Etching process is suitable for the processing and production of antique handicrafts and jewelry with special requirements on surface style.

Hot stamping: Hot stamping process is often used in printing. The material he uses is alumina or copper powder, which is attached to printed matter by the pressure of fonts at high temperature, but it is not a gold processing technology.

But under special circumstances, gold powder is also used for bronzing.

Such as publications, awards, certificates, etc. with far-reaching significance, high grade value and great influence.

3. 1 overview of process flow: wax plates are needed for lost wax casting, and rubber molds pressed with silver plates are needed for mass production of wax plates.

The production of the silver plate depends entirely on the manual skills of the plate maker. The original plate has sharp edges, clear lines and smooth surface. It is made of 925 silver and is made by sawing, filing, welding and cutting.

It is the most demanding process in jewelry making process, which requires that the surface, hollowed-out part and back of the silver plate are clean and seamless, the structure of each part of the silver plate is reasonable, the position and size of the inlaid gems are accurate and seamless, and some also require pretreatment of the inlaid parts.

For the silver plate with complex structure, it is very difficult to use the general welding method because there are many parts, so it is necessary to use the blank placing method to complete the production.

After preparing the silver plate, you can enter the lost wax casting process.

The technological process of lost wax casting is as follows: rubber pressing mold-rubber opening mold-wax injection (mold)-trimming wax mold (wax welding mold)-planting wax tree (weighing)-pouring gypsum pipe-vacuumizing gypsum-naturally setting gypsum-baking gypsum-melting gold, casting-frying gypsum-washing, pickling, cleaning-cutting the blank holder mold to be asked.
