The creation of blue and white porcelain in the Yuan Dynasty is an epoch-making event in the history of ceramics. Since then, colored porcelain with blue and white as the main body has become the mainstream variety of porcelain, the color glaze that has always occupied the mainstream position in the past has relegated to a secondary position, and the aesthetics of ceramics have entered the colorful modern era from the middle age of simplicity and beauty.

The most critical and primary problem of Yuan Qinghua is to distinguish between true and false. In this video, Zhao Zhe, an ancient ceramic/jade/bronze appraiser of the Domain Forensic Platform, will talk about the identification characteristics of Yuanqinghua porcelain through a series of Yuanqinghua porcelain pieces.
The identification of yuanqinghua porcelain we have to explain from the tire, glaze, and painter, these aspects.
First of all, let's talk about this yuan blue and white porcelain tire, it is relatively dry, but more moist, the current imitation, most of the tires are relatively wet and tender, because its tire soil, did not go through the ancient times such a long time of staleness.
Let's take a look at the tires of ancient porcelain. From its cross-section. This tire is still relatively dry
And there's this pore inside. Modern porcelain burnt porosity is relatively low, the degree of porcelain is very high, and unlike this old porcelain tire, its porosity is still relatively high.
Yuan qinghua porcelain glaze in general is still white in the blue, cyan is a degree, the modern imitation color is too green, or too white, are not right, green material penetrates on the tire glaze and the effect they can not be burned into reality.
Meta blue glaze color can be divided into this egg blue and blue white, blue and white glaze, also known as shadow blue glaze, the body tire glaze slightly flashing blue, slightly light blue in the warm, in addition to the foot circle appears aqua green, the body tire glaze often shows pale tooth yellow, sometimes show milky white, its color will vary slightly with the humidity in the air, temperature changes. Egg white glaze, glaze feel warm as jade, soft and not dazzling, such as too bright or strong light highlights, it is worth considering.
It can be seen from the red porcelain pieces in the glaze of this Yuan Dynasty that its glaze is obviously blue, and the glaze of Yuan Qinghua has a certain thickness.
Through this specimen, it can also be seen that the difference between the shrinking glaze point of the genuine and the imitation, the edge of the shrinking glaze point of the true yuan qinghua is bulging up, while the shrinking glaze point of the modern imitation is a flat, and it does not have the three-dimensional sense of the glaze on the edge of the genuine product.
There is also a runoff of the glaze of the old porcelain, the wetness of the genuine product is very good, the glaze is relatively thick, there is no kind of thief light, because after all, it is the Porcelain of the Yuan Dynasty, whether it is handed down or unearthed, it has gone through a thousand years of time, it has no thief light, this luster, the sense of light is very good, very warm. You see this is a large pot of yuan qinghua, the glaze and tear marks in the jar have been very thick, white and green, and the glaze is very natural There is this flint red, and the gloss of the glaze is warm as jade.
No matter what kind of porcelain, we must look at the reflection, through the reflection we can see the authenticity of this porcelain, but this requires the accumulation of experience, not that I teach today, everyone can learn immediately, which requires long-term practice and application
And the glaze of this old porcelain, it also has this kind of bump marks and traces of use, as well as a long time circulation, is what we call this kind of pulp, look at it unnatural, if it is a modern imitation, most of them are washed out with acid, so that the glaze is very different from the real thing.
