    The large blue and white porcelain in Zhou Xia's hands is quite in line with the style of Yuan Dynasty porcelain, which is thick, large and powerful.

    Although he did not use accurate measuring tools, Zhou Xia was still able to estimate that the diameter of this large blue and white plate was about 40 centimeters. Among the porcelains of the Song Dynasty, we rarely saw such large-scale vessels, especially this type.  of the market.

    Such characteristics have also become a typical feature of Yuan blue and white. The later blue and white porcelain of Ming and Qing Dynasties was elegant and beautiful. Blue and white porcelain with obvious roughness like this is really rare.

    Although the system has identified it, it is a precious cultural relic.

    But Zhou Xia still hopes to use his own eyes to experience the beauty of it. This is also a rare experience for him.  Although Yuan Qinghua has fallen from the altar and is no longer a myth, it is still a rare treasure.

    Since this large blue and white plate has been broken into several halves and has not been completely repaired, it is easier to identify.

    The reason is well known to everyone. You can see the full picture of the fetus inside quite clearly.

    In ancient times, there was no mechanical drawing method like today. At that time, it was all made by hand.

    Therefore, when observing under a magnifying glass, it can be clearly seen that the bubbles inside are uneven in size, some are large and some are small.  The large blue and white plate in Zhou Xia's hand is just like this, and it feels a little transparent.

    Zhou Xia has seen a lot of modern imitation Yuan blue and white before, with even bubbles, and some even have obvious mechanical lines.

    In addition, Zhou Xia also gave full play to his subjective initiative.  Combine the theoretical knowledge he has learned with the actual situation at hand.  Conduct a more in-depth comparative analysis on the blue and white porcelain in your hand.

    According to records, most of the fetal bones of Yuan blue and white are kaolin mixed with porcelain stone, which is called a binary formula.  As early as the Five Dynasties, this formula had been invented in Fanchang kiln and the blue and white porcelain of the Northern Song Dynasty.  Due to the different kilns producing Yuan blue and white, the characteristics of the fetal bones are different.  The formulated tires have a certain degree of strength and flexibility and can control high-temperature deformation to a greater extent.  Ensure the molding rate of large items.

    Therefore, it is not surprising that Yuan blue and white jars weighing hundreds of kilograms, as well as huge plates, bowls, and some porcelain are even so large that people are shocked.

    Zhou Xia observed carefully and found that it was indeed as mentioned in the information. The bottom of the blue and white plate appeared to be very soft but not particularly loose.  Compared with the blue and white porcelain of the Ming and Qing Dynasties, it feels not so hard.  Zhou Xia pondered.  It is precisely this kind of porcelain body that can make such a large device.

    After seeing the porcelain body, Zhou Xia made a detailed appraisal of the glaze of the blue and white plate.

    Needless to say, the glaze of this porcelain must be as smooth and beautiful as possible.  Just like those porcelain pieces that Zhou Xia harvested before that were suspected of being Chai porcelain, the glaze.  It is so beautiful that it cannot be compared with other porcelain.

    Zhou Xia saw on the surface of this blue and white porcelain that in addition to the usual blue and white, there was also an egg white color where the glaze accumulated.  Even the presence of aqua green was discovered.  This is because part of the glaze juice is added with glaze fruits, so it looks plump and heavy.  This is also an important feature of Yuan blue and white.

    He took a magnifying glass and looked up again, and he could clearly see that in addition to the slight orange peel glaze and glaze shrinkage, some bubbles even appeared reddish brown.

    He didn¡¯t find it strange at all. This situation just proved what Agula said, indicating that this was an unearthed artifact.  If it is buried underground for a long time, it will inevitably be eroded by water and soil, and then it will appear reddish-brown like this.

    In addition, this large blue and white plate was not well kept after it was unearthed, leaving some traces of stumbling and wear.

    Such performance has also greatly affected the value and price of this blue and white market.

    ¡°In addition, this blue and white platter is not a complete instrument, so it¡¯s no wonder that Agula has hit a wall before. After repair, it may be able to be put on the auction, but as it is now, many auction houses will not take it over.  And Agula's expectations are relatively high, and he wants to sell it for millions. Therefore, it is not accidental that he brought this thing to the East China Sea. After all, everyone's money is not easy to come by, and they will not be easily taken advantage of by Yuan Qinghua.  Such a name can fool people, especially those old experts and auction houses that have been in the field for a long time.

    As far as Zhou Xia is concerned, if this porcelain is not systematically identified as a precious cultural relic, based on his personal perception, it will not do anything to it.  There is no other reason for this. The appearance of this piece is really poor. Although it is not regarded as a porcelain specimen, it certainly will not be purchased at a high price.

    However, at the moment, Zhou Xia is anxious to collect precious cultural relics in order to achieve his goals, obtain achievements, and unlock the next skill. Even if the appearance is not good, he is still thinking about it.Even if you spend more money, you still have to get it.

    After that, Zhou Xia carefully observed the blue and white material used in this large blue and white plate and confirmed that it was imported Suma Liqing.

    This is also the imported cobalt oxide commonly used in Yuan blue and white paintings. At that time, it was traded or purchased with ancient Persia for porcelain, silk, and tea.

    Such imported materials are the same as the suma-liqing used in the blue and white porcelain of the Yongxuan period.  They all have the characteristics of high iron and low manganese, with irregular dark brown patches or tin light spots, and a concave and convex feeling, with the phenomenon of halo, sinking, gathering of wires, nets and beads.  Some are flowing, and some are purple.  The blue and white hair color has the effect of green, rich and different shades, and some can produce the art of ink painting.

    But there are obvious differences in the hair color of Yuan blue and white and Yongxuan blue and white.  Yongxuan blue and white are obviously much brighter and clearer, while Yuan blue and white are darker.

    According to Zhou Xia¡¯s own speculation, it is probably due to technological progress and the influence of many factors such as kiln temperature, tire quality, glaze color, and ingredients, that the blue and white porcelain of various eras show different colors and characteristics.

    Zhou Xia also paid special attention to the painting techniques and characteristics displayed on this blue and white porcelain plate.

    Craftsmen of the Yuan Dynasty absorbed the essence of the paintings of their ancestors and integrated Chinese and Western cultures to fully display their superb art on blue and white porcelain.

    No, the overall expression of the painting style on blue and white porcelain is: rough and bold, free and easy, skillful and smooth.  The composition is full, complex but not chaotic, one stroke at a time, and it is completed in one go, fully demonstrating the artist's artistic attainments and profound skills.

    Finally, Zhou Xia also used the system to conduct an appraisal, hoping to confirm the age of the blue and white porcelain.

    Although this blue and white porcelain has countless characteristics of Yuan blue and white, it would be embarrassing if it turned out to be a big mistake.

    Fortunately, the system did not disappoint him, and it was finally identified that this blue and white plate was made in 1303 AD, which was the Yuan Dynasty. In this way, those who doubted the existence of Yuan blue and white can dispel their doubts.
