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.

Scanning of ceramic relicsThe following are some examples of scanning ceramic relics:
- In the case of the Northton Cultural Relics 3D Scanning Project, the Northton technical team used 3D laser scanner, high-definition texture camera and other digital acquisition equipment to scan the cultural relics (including porcelain, etc.). During the scanning process, the position of the scanner was adjusted according to the shape of the cultural relic, and the 3D data was obtained by moving around the cultural relic. Then, the point cloud data was imported into the post-processing software for editing, stitching, fusion, network modeling, model refinement, texture mapping, etc. Finally, a high-precision 3D digital model of texture was generated.
- During the special exhibition held at the Aichi Prefecture Museum of Fine Arts in Japan, the curators, Mr. Onishi Ryo and Mr. Inoue Hayata, used the 3D Einscan Pro 2X multi-functional 3D scanner to obtain high-precision 3D data models of ancient pottery. They uploaded the model data to the Google Poly display platform and created a QR code. The audience could scan the QR code on their smartphone to read the 3D dynamic model of the exhibited works.
- The senior engineer of the Guangzhou Electronic Science Education and Intelligent Manufacturing Department of the Chinese Academy of Sciences demonstrated the rapid scanning case of ceramic products (such as cultural relics ceramic tea cups). The color hand-held portable 3D scanner of the Chinese Academy of Sciences was used, which could quickly scan and image porcelain. The data came with color texture, which could realize the purpose of data file preservation, 3D digital display, and later reproduction for display.
- In the service case provided by Guangzhou Electronic Science and Technology of the Chinese Academy of Sciences for an international cultural relic auction association in Guangzhou, the 3D scanning data of the Han Dynasty ceramic vase crafts were collected through a high-precision laser scanner, and then imported into professional software for model adjustment and modeling, as well as detailed feature engraving and retouching. Finally, the physical model was produced by 3D printing technology.

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.
