Ru Ci's fetal quality is exquisite, and the fetal soil contains trace copper. Looking at it under the light, it is slightly red, and the tire color is slightly yellow, commonly known as "fragrant gray tire". More common in Luanchuan Yanhedian, Dayu Donggou, Ruzhou Confucian Temple, Liang Qing Temple and other kiln sites. Rukiln ware in Zhanggong Lane, Ruzhou has a kind of gray tire, which is slightly whiter than other kiln mouths, which is the main feature of the official kiln in the Northern Song Dynasty.
Second, look at the glaze color.
Ru Ci was monopolized by the imperial court and used agate as glaze regardless of cost. Glaze colors include sky blue, pink and sky blue, as well as bean green, turquoise, moonlight and orange peel. The glaze is moist and soft, pure as jade, with obvious ghee, slightly translucent glaze color, mostly opaque or crystalline.
Third, look at enamel.
The glaze of the genuine product has been in contact with the air for a long time, and the glaze has an antique feeling, but it can also be identified by enamel. The glaze is even, with bubbles and no fluffy flowing traces, and vice versa. Through a magnifying glass more than 30 times, the bubbles in the real thing are clearly visible, like imitation bubbles flashing in the morning star, such as piled soap bubbles.
Fourth, look at Zhi Ding.
Porcelain used in Ru kilns in Song Dynasty was generally glazed and fired. In order to avoid the pollution of impurities in the kiln, saggers should be used for packaging, and washers and Zhi Ding should be placed on the products to prevent adhesion with saggers. There are three, five or seven Zhi Ding marks as thin as sesame seeds on the bottom of the artifacts, and six Zhi Ding marks are rare, shallow and the size of rice grains.
V. Types of viewers
Ruyao products include daily utensils, such as bottles, statues, lamp holders, bowls, plates, washing utensils, urns, narcissus pots and so on. A few of them are decorated with flowers and prints, and there are blue and white year numbers at the bottom. Most of them are painted with knives and pens, printed and stamped. And the real thing is thick and textured, like fat; The imitation is exquisite and light in weight.
Six, look at the edge of the mouth
Compared with other parts, the edge glaze color of the genuine product is slightly thinner, and the glaze color of the mouth is slightly copper red. If there is a grinding bottom at the bottom of Ru Ci genuine product, the exposed part is a fragrant gray tire color; The raw materials used in imitation tires do not belong to Ruzhou, so the glaze color at the edge is very light (commonly known as blurting out, also known as revealing white), and even becomes a colorless and transparent glass body.
Seven, look at the pattern.
Glaze pieces are fine, mostly oblique, and the depth is intertwined, like silver scales or cicadas, giving people a layered feeling. Fine trachoma in glaze is caviar pattern, sesame flower and crab claw pattern. There are typical orange peel glaze, borneol glaze and tea foam. When the hand pulley rotates, some willow-shaped pieces are formed due to the certain orientation of the molecular arrangement structure of the mud.
