Jilan ceramic
Blue 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. The novel "Listening to the Rain in Green Bamboo and Watching the Egrets" is equally wonderful.

ceramic gilding technique
The 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. The novel "Gilded Palm" is equally exciting. Everyone is welcome to click and read it!

Scanning in the phone photo
There were many ways to implement the scanning function in the mobile phone camera. Some mobile phones came with a camera APP with a scanning function. For example, a Huawei mobile phone could take photos and scan paper documents by clicking the document correction function in [More]. There were also some third-party applications that could also implement the scanning function, such as the scanning and counting king app. After downloading and installing it in the mobile phone, click [Tools], and find the [Scanning Files] function under [Scanning and Storage of Files] to take a photo and scan. The Cloud Scanning King app. After downloading, installing, opening, and reading the agreement, select "document scanning", open the camera and local camera permission, and you can directly shoot at the document or import pictures from the local photo album to scan. The phone's photo scanning function was convenient in converting paper documents into electronic versions, but there were some differences between the two. The scanned document was an electronic version of the original document with high resolution because the scanning device could accurately capture the details on the paper through specific technology. The resolution of the mobile phone photo depended on the phone's resolution and photography skills, and was easily affected by factors such as light and hand shake. The size and proportion of the scanned document were exactly the same as the original document. The size or proportion of the photo might be different from the original document due to factors such as shooting angle and distance. The color of the scanned document was balanced and uniform, which could accurately restore the color of the original document. The color of the photo may be distorted by environmental light, mobile phone camera, and other factors. The scanned image usually did not contain information such as the time of the shot, the focal length of the camera, and so on. The image file left behind by the photo would contain these additional information. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
