Bronze sculpture: the type and maintenance of bronze sculpture
Bronze sculpture : The main varieties of bronze sculptures of bronze sculptures are brass sculptures, bronze sculptures and bronze sculptures. The maintenance of bronze sculptures insists on the original appearance of bronze sculptures. There is a problem of preservation and preservation. The bronze sculptures are oxidized in the ground for a long time, and the texture is not consolidated. Especially the semi-de-boss bronze sculptures are even more vulnerable than porcelain. Therefore, the bronze sculptures are properly preserved. To avoid damage after unearthing, it is very important for investors.

The history of cast bronze sculpture cast copper is very long and skillful. The process of casting copper is more messy than forging copper, and the restoration of artistic creation is good. Therefore, it is suitable for becoming a material of precision works. It is very popular among artists, and special character sculpture is the most common. But it is easy to oxidize, so pay more attention to maintenance.
The process of forging bronze sculptures forging copper sculptures is to first make a mold, and then use a special glue to fix the fixed position. After the copper plate is heated, the softened copper plate is placed on the mold and hit with a hammer. After hitting, the hammer is hit. Restoration and consolidation, so that it can be formed. If the copper plate is hardened without repeated heating, it is best not to go over three times, do a good job of immersing in the copper sulfate in the rear, and finally make art works or other days, industrial supplies.
The main raw material for the bronze sculpture of copper sculpture: copper. Copper is a simple substance of copper, named for its purple color. See copper for various properties. Copper is industrial pure copper, its melting point is 1083 ° C, no homologous change, the relative density is 8.9, five times that of magnesium. It is about 15% heavier than ordinary steel. It has a reddish color of rose, and its appearance is purple after it forms an oxide film, so it is generally called copper. It is copper containing a certain amount of oxygen, so it is also called oxygen-containing copper. Brass can be used to make good quality copper sculptures. 
The unearthed bronze sculptures are often muddy and turbid, the texture is unclear, and the proper cleaning is carried out to allow the soil to fall by itself, and then rinsed quietly with a small brush. When encountering soil rust that affects the decoration, it can be slowly removed with a small bamboo stick. Use a copper brush or a hard brush to rinse, but you can't use a sharp tool to finish the polishing. Otherwise, the bronze sculpture will be destroyed and the preservation value will be lost.
So how do you maintain the bronze sculpture?
1 silver oxide method. Touching with silver oxide and cuprous oxide, the exit surface of cuprous chloride is turned off, and the intention to control the corrosion of the copper sculpture is reached. First, by mechanical means, the powdery rust is removed to reveal a grayish white wax of cuprous chloride. Then, the silver oxide and the alcohol are adjusted into a paste, coated on the surface of the cuprous chloride, and placed in a humid environment to make it rich, forming cuprous oxide and copper chloride, covering the appearance of cuprous chloride. Both are stable salts, so repeated operations, until the utensils are placed in a high-humidity environment, the corrosion point of the powdery rust does not stop. This method is suitable for mottled local corrosion artifacts and fixtures with metal inlays.
2 benzotriazole method. Benzotriazole is a heterocyclic compound, which can form a stable complex with copper and its salts. It forms an insoluble and properly sturdy clear maintenance film on the surface of the copper alloy, so that the copper engraving is pressed and stabilized, avoiding water vapor. And erosion of air pollutants. Using an organic solvent such as distilled water and toluene or acetone to remove the oil from the surface of the copper engraving, and then immersing it in a solvent of benzotriazole alcohol to form a complex maintenance film. However, benzotriazole is susceptible to heat and loses maintenance. Therefore, a layer of polymer material should be applied to the exterior of the copper sculpture to make a sealing film.
3 lye soaking method. The corroded copper engraving is immersed in a sodium sesquicarbonate solution to gradually convert the copper chloride into a stable copper carbonate, and the copper ions of the copper engraving are replaced and transferred into the infusion. The immersion liquid should be replaced on time, until no chloride ions in the immersion liquid stop. Subsequently, the utensils were repeatedly washed with distilled water, the lye was removed, and the mixture was sealed after drying. The alkali solution extracts only the chloride and retains the corrosive layer of colorful malachite, which does not harm the original appearance of the bronze sculpture. The defect of this method is that the displacement reaction time is long; other chlorides are not only attached to the surface of the rust layer, but have penetrated into the deep part of the crust, which is difficult to replace completely.
