2. The type of the viewer (there are differences in porcelain types in different times)
3, look at the glaze (from the glaze can also be divided into years and regions)
4. Look at the luster/color (the luster of porcelain in different periods is different, and the color is also different)
5, look at the pattern (look at the pattern, it may be a master's handwriting, different painting styles in different times, different patterns on porcelain)
6. Whether it is intact (how to preserve it is also an important factor to determine its value, and inferring the age from the damaged place is also one of the methods of dating)
Judging from the glazed red porcelain handed down and unearthed in the Yuan Dynasty, it is the same as the blue and white porcelain of the same period in terms of shape, embryo, glaze and firing process, with the following differences:
(1) The decorative pattern is relatively simple, unlike that of blue and white porcelain.
(2) The theme of decorative patterns is correspondingly reduced, which is not as rich and diverse as blue and white porcelain.
(3) Copper is easy to play with at high temperature, so the underglaze porcelain in Yuan Dynasty has no light color, only a strong color scale, and the decorative lines are often dizzy.
(4) The copper pigment is very sensitive in the firing process, and the atmosphere in the kiln room can't achieve the expected effect with a slight change, so there are few pure red porcelain in the glaze of the Yuan Dynasty.
Finally, the success of coloured glaze. Egg white glaze, red glaze and blue color fired at high temperature are the signs that Jingdezhen porcelain-burning workers are proficient in various colorants. The above are several aspects of identification, and my knowledge is limited. What netizens say is only speculation, so you'd better go to the local cultural relics department to find an expert to be firm (the purpose is to date and analyze rarity and preliminary evaluation).
