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.

What are the induction contradictions?Inductive paradox was an important concept in mathematics and logic. It referred to situations that could lead to errors or contradictions when drawing conclusions based on certain premises. The following are some of the most common induction contradictions:
1. The universal theorem: Assuming that all animals can fly, then one bird must be able to fly, two birds must be able to fly, and so on, all animals can fly.
The necessary condition contradiction: Assuming that all animals can fly, then a bird must be able to fly, but if this bird can't fly, then other animals can't fly either. Therefore, it was concluded that it was necessary for all animals to be able to fly.
3. Paragon of sufficient conditions: Assuming that all animals can fly, then a bird must be able to fly. If this bird can fly, then other animals can also fly. Therefore, it was concluded that it was a sufficient condition for all animals to be able to fly.
4. Bayes 'Paragon: Assuming that the probability of A is p, then if the probability of A is 1-p, then the probability of B is p. However, if the probability of A is p, then the probability of B is not p. Therefore, it is concluded that when the probability of a certain event A is p, the probability of B must be less than p.
These contradictions showed that there could be mistakes or contradictions in the conclusion of some premises in the process of induction. Therefore, in the process of induction and reasoning, it was necessary to carefully verify and select the premise to avoid producing a contradiction.

Stir-fry in an induction cookerThe New Emperor Heavy Fire Induction Cooker was a type of induction cooker with the ability to stir-fry on high heat. After 80 seconds of turning on the induction cooker, the temperature could reach 680 degrees or more. The firepower was better than that of a gas stove, and it could easily achieve high-temperature stir-frying. In addition, there were other brands of induction cookers that also provided the function of stir-frying, such as the Subo induction cooker and the Demas commercial induction cooker. However, there was still a certain gap between the firepower of the induction cooker and the open fire cooking. Because the Chinese had higher requirements for the heat when cooking, the firepower of the induction cooker was not enough to meet the needs of stir-frying. Therefore, although the induction cooker could achieve stir-frying with high fire, stir-frying with open fire was still the preferred cooking method of the Chinese.
How to use the induction cooker?The method to use the induction cooker was as follows: First, place the induction cooker in a well-vented place to better dissipate heat. Secondly, make sure that the quality of the socket is good, the plug wire is not damaged and inserted into the socket firmly to prevent the induction cooker from not working properly due to poor contact.
