The repair and maintenance of bronzes, how to maintain bronzes

Copperware maintenance needs to be prepared: rags, water, white vinegar.

1. First take out a bottle of white vinegar and drop it onto the copperware.

2. Then take out the rag and wipe the surface of the copper as shown in the figure below.

4. Use a soft rag to polish the bronze as shown in the figure below.

1. Tin soldering method: using the metallicity of the bronzer fracture, the soldering iron is heated, and the solder is welded to restore the broken bronze.

2. Instrument shape making method: according to the size of the incomplete plane of the bronze, cut a similar copper sheet, after heating, use the ductility and plasticity of the copper, use the malleability and plasticity of the copper, and use a special shape of the long hammer to beat out the shape of the original tool, and then supplement the broken bronze.

3. Sand casting method: use the intact part of the bronze itself as a model, make the molding sand or clay into the outer model, cast it into the metal fittings of the broken part, and then supplement the missing bronze.

4. Pattern engraving method: use a variety of self-made chisel knives, according to the outline of the pattern that has been copied and painted (gluttonous pattern, kui pattern, thunder pattern, etc.), carve by hammering and pressurizing method, and re-engrave and polish the file repeatedly against the original pattern, until the pattern is as fine as the original pattern.

5. Pattern carving and inlay method: the original pattern is copied and painted on the accessories, and the appropriate chisel knife is selected to carve (cut) into the pattern groove, and then the inlaid metal (copper, **, ** and other sheets or wires) is embedded in the pattern groove with special chisel tools under pressure, and the file is smooth.

6. Gilt and gilt silver method: commonly known as "fire gold-plated silver". Heat with mercury to melt ** and ** respectively, make gold mud (gold amalgamation) or silver mud (silver amalgamation), and then clean the bronze fittings with acid solution, and then evenly smear the gold mud or silver mud on the fittings, heat with charcoal fire to evaporate the mercury, so that after plating, after 2 or 3 times, the plating parts are immersed in soaphorn water, and the copper wire brush is used to scrub evenly, showing the gold or silver metallic luster, and finally rolled with agate gin.

7. Fake rust method: use lacquer and various powdered non-water-soluble pigments to blend into various colors of paint paste and lacquer mud, refer to the corrosion phenomenon of the bronze itself, and make the same image of "earth" and "rust" to cover up the traces of bronze repair.

8. Rust removal method: use acidic or alkaline items to act on the bronze, and remove the bronze rust after dissolving or relaxing, and restore the bronze pattern or inscription.

Hello, I'm happy to answer for you, first of all, you have to determine whether the copper button can be taken down, it is difficult to repair if you can't take it down, because the iron heat dissipates quickly, which is not conducive to welding, if you can take it down, it will be simple, you can reinstall it after welding, if it is not a practical device, in order to decorate, you can use glue to bond, this is not recommended, it is best to help you see it in the last picture.

Hello master, that's it.

Owner: Hello.

Copperware: Oxygen-acetylene burned copper electrode for brass, and the flux is borax, or brazing powder.

Copper uses an electric soldering iron to melt the solder bar, and the flux is solder paste.

To maintain the bronze, you need to clean the bronzes regularly, the bronzes may have soil spots, rust spots, grease, etc., which can be cleaned with distilled water, and after cleaning, you need to rinse with distilled water several times. The temperature and humidity should be well controlled, and the storage area must be kept dry, and the temperature is recommended to be between 18 and 24 degrees.

Maintenance method of bronzesBronzes may have soil spots, rust spots, grease, sweat stains, etc., which need to be cleaned regularly. To clean the bronzes, you need to use distilled water, first warm the distilled water properly, and then clean it with a cleaning agent, and after cleaning, you need to rinse it with distilled water many times to avoid damaging the utensils.

When placing bronzes, you need to take care to control the temperature and humidity. The storage environment of bronze ware needs a relatively stable temperature and humidity, and the storage place must be kept dry and leaky, and the temperature must be kept at 18 degrees to 24 degrees including travel, and the relative wet rejuvenation degree is best to be below 40% to avoid moisture.

Bronzes should avoid contact with harmful liquids and gases, should not be coated with thick grease on the bronze, must wear cotton gloves when touching bronzes, can not be touched with sweaty hands, so as not to cause corrosion to the surface of bronzes.

Bronzeware is an instrument made of bronze alloy (an alloy of red copper and tin) that continuously reacts with the soil from the time it is buried, producing various green, blue, red, and black rusts. The bronze absorbs water after being corroded, which accelerates the corrosion rate of the bronze body until the bronze body becomes patina.

The bronze has a long-term effect with a variety of surrounding chemicals in different environments, and a layer of oxide film is generated on its surface, the color of the skin shell is warm and moist, and the texture of the potato town is thick, and there are a variety of skin shells such as jujube skin red, green lacquer, black lacquer, black-green, yellow-green, etc.

Most of the unearthed bronzes show different shades of green rust, and there are also some bronze brigade cleaning vessels with blue rust, black rust, earth rust and red rust mixed in the thin green rust on the surface. The green rust is mostly from the bronzes in the cellars, which are atmospheric corrosion in a closed environment because they are not in direct contact with the soil, while the bronzes are quite stable in the weak and moderate concentrations of non-oxidizing acids due to lack of oxygen.
