Jilan ceramicBlue porcelain was lime soda glazed porcelain with tungsten dioxide as the coloring agent. Its glaze color was also known as "blue","sacrificial blue", etc.
The earliest application of this kind of ceramic coloring agent can be traced back to the Tang Dynasty. The appearance of blue Jun glaze in the Song Dynasty laid a certain foundation for the development of blue porcelain. Jingdezhen kiln in the Yuan Dynasty started to create blue porcelain. At that time, due to the use of high-temperature tungsten ore from the Muslim countries, blue porcelain was successfully fired. However, the production of blue porcelain in the Yuan Dynasty was small. Except for museum collections, there was little folk circulation. The successful firing of the Yuan Dynasty sacrificial blue glazed porcelain laid a good foundation for the development of the Ming and Qing dynasties.
During the Ming Dynasty, the firing technology of the blue porcelain was constantly developing. The Xuande dynasty's blue porcelain craftsmanship and glaze color were obviously improved. The hair color was deep and bright, and there were rust spots in the glaze. It was the pinnacle of blue glaze firing at that time. During the Chenghua, Hongzhi, and Zhengde periods, there were not many blue glazed porcelains handed down from generation to generation. Blue glazed porcelain was more popular in Jiajing and Wanli periods, and there were new developments in the types of shapes and glaze colors. After the Wanli period, blue glazed porcelain was basically extinct.
In the Qing Dynasty, during the Kangxi period, the blue glaze became popular again. The sacrificial blue and blue flowers used materials with a high content of Cobalt. The color was strong, and the glaze was thin and smooth. During the Yongzheng and Qianlong periods, the use of tungsten changed, and the iron content increased. The color of the blue glaze during the Yongzheng period was not as elegant as that of the Kangxi period, but the color was dark blue and the glaze color was gorgeous. In the Qianlong period, in addition to the traditional blue glaze porcelain, there were many complicated techniques derived from the single color. For example, the blue glaze was first fired at high temperature, and then the gold pattern was painted on the glaze, and then it was baked at low temperature. However, this technique was complicated and difficult to preserve. In the Qing Dynasty, the blue glaze porcelain was mainly made of palace sacrificial vessels and furnishings. The official kiln's blue glaze was mostly made of official style and exquisite workmanship. The civilian kiln was mostly made of temple sacrificial vessels. There was no official style and most of the products produced in Jingdezhen were dated.
Blue porcelain was mainly glazed on sacrificial vessels, luxurious furnishings and sacrificial porcelain. Its color characteristics were similar to bright red glaze. The glaze surface did not flow or crack, the color tone was uniform, and the color was stable. Under the high temperature, the glaze layer melted and flowed down, causing the mouth of the object to become thinner along the glaze layer, revealing the white fetus bone, commonly known as the " lamp grass mouth ". The glaze layer at the bottom flowed down and piled up, showing a blue-purple brown color.

ceramic gilding techniqueThe ceramic gilding technique was a process of metalizing the surface of ceramic products with gold. One way was to apply gold glaze (an overglaze glaze made of gold powder, lead siliconate, essential oil, and other materials) on the surface of the ceramic. The gold glaze would appear dark brown in its natural state. After baking it at a low temperature, it would be polished with beeswax or agate.
There was another process: Porcelains are made by plain firing or with only a layer of diluted glaze. After cleaning, the surface is coated with silver.(A thin layer of silver paste is evenly coated on the surface of the porcelain, and after drying at a temperature of 200 - 300 ° C, the process is repeated for 1 - 2 times. After the silver paste is coated for the last time, it can be directly fired. After the firing temperature reaches 500 - 800 ° C, and the preferred temperature is 600 - 700 ° C, the temperature is kept for 15 minutes- 3 hours, and the preferred temperature is half an hour- 1 hour. After that, it is cooled to normal temperature. The silver paste is then fired and reduced.) forming a silver layer on the surface of the porcelain), then nickel-plating, then copper-plating or titanium-plating, and then gold-plating to obtain the gold-plated product. This method increased the thickness of the base layer by using cheap metal. On the one hand, it could save the amount of gold used, and on the other hand, it could greatly improve the quality of the product, especially for the production of more complicated parts.
The ancient gilding process was also known as fire gilding. It was to synthesize gold and mercury into gold mercury. The coating was heated to more than 400 ° C to evaporate the mercury. The gold was attached to the surface of the ware, and then a "press" made of agate or jade was used to press along the surface of the ware to make it shine.

Internet celebrity nano coating agentThe situation of the nano-coating agent was more complicated and could not be simply classified as a scam, but there were some cases where some merchants exaggerated their publicity.
In the field of nano-coating solution for mobile phones, there were merchants who deceived consumers. The nano-coating liquid was a nano-coating. Its real purpose was to improve the feel of the phone screen and prevent fingerprints from being difficult to erase. The effects of the phone screen being intact after being smashed by a hammer, knife, or walnut had nothing to do with the coating liquid itself. Because the phone screen itself had a nano-coating, it was unnecessary to buy the nano-coating liquid.
As for the nano-coating agent for cars, some products claimed to have dust-proof, anti-pollution, oleophobicity and other effects. It could be coated with one spray and one rub. The operation was simple and the effect was good, but there were also opinions that the nano-coating solution for cars was IQ tax.
There was also an electronic protective nano-coating agent, which could be used to protect electronic products and enhance their functions. For example, by soaking, drying, and other simple operations, it could form an ultra-thin dense transparent coating on precision electronic components. It had waterproof, high and low temperature resistance, salt fog resistance, and other properties. The nano-anti-sticking coating of the medical scissors was food grade and had passed the FDA certification. It had the effects of anti-sticking various liquids, non-sticky, and easy to clean. The nano-coating agent for LED small-pitch display screens can improve the ink color and prevent moisture erosion.
Therefore, in the face of nano-coating agents, consumers should treat them rationally and not blindly believe the exaggerated function advertisements of merchants.

What is the effect of the coating on the welding rod?The coating on the welding rod mainly had the following functions:
1. It was to ensure that the deposited metal had a certain chemical composition and performance, and it was made into a coating by mixing the powders such as an oxide-based alloy, a carbonate-based alloy, a silicate-based alloy, an organic compound, a fluoride-based alloy, and other chemical powders according to a certain proportion to meet the needs of welding.
2. In the process of welding, molten slag with suitable physical and chemical properties such as melting point, density, and basicity was formed to ensure the stable combustion of the electric arc and the easy transition of the molten metal. An atmosphere was created around the electric arc area and the molten pool to protect the welding area and obtain good formation and performance of the welding line.
3. By adding deoxidiser, permeating alloy elements or a certain amount of iron powder into the coating, it can meet the requirements of the performance of the welding metal or improve the melting efficiency.
4. The arc-stabilizing agent in the coating can make it easy for the welding rod to start the arc and maintain the stable combustion of the electric arc during the welding process; the slag-forming agent can form molten slag to protect the welding droplets and the molten pool metal and improve the shape of the welding line; the deoxidiser can reduce the oxygen content in the welding line metal and improve the performance of the welding line metal; the gas-generating agent can decompose gas to form a protective atmosphere to protect the electric arc and the molten pool metal and prevent the invasion of oxygen and nitrogen in the surrounding air; Alloying agent is used to compensate for the loss of alloy elements in the process of welding and to transfer alloy elements into the welding line to ensure the chemical composition and performance of the welding line metal; plasticizer can improve the elasticity, elasticity and mobility of the coating during the process of pressing and coating of the welding rod, and improve the quality of pressing and coating of the welding rod; Binder can firmly bond the coating material to the core of the welding rod, and make the coating of the welding rod have a certain strength after drying.
5. isolate the air to prevent the nitrogen, oxygen and other gases in the air that are harmful to the smelting reaction of the welding pool from entering the pool. The molten slag formed after the melting of the welding rod covers the surface of the welding line to protect the welding line that has not been completely cooled. It reduces the cooling speed of the welding line, which is beneficial to the escape of gas, prevents the formation of pores, and improves the structure and performance of the welding line.
6. It participated in the complex smelting reaction, permeating the required alloy elements into the metal of the welding line, and played the role of controlling the chemical composition of the welding line to obtain the required performance of the metal of the welding line. For example, adding Si, Mn and other alloy elements in the coating could remove the harmful gases and impurities such as deoxidization, desulphurization, dephosphorous, etc., and improve the quality and performance of the welding line.
