The glaze is thick and heavy like an iron spot, and the thick is thick and thick before the spots appear.
The color of the plaque is thick with a presser, and it can be seen that the bottom of the spot is not deeply drilled.
The size of the false spot is unnatural, and the counterfeiting can be seen with hard work.
Brown does not eat heavy fetus shallow, true and false eating fetus do not look biased.
Fake like sticking to the thick color, really naturally drilling into it.

note
In order to counterfeit, some people use heavy glaze or use heavy pen, heavy color, pressed pen and other methods to create drill tire marks, although they use their brains to specialize in counterfeiting, but they are not natural, and there is a big difference between them and really:
First, there are no spots on the counterfeit in a certain sense of color, and there are real spots, and the brown color of the counterfeit is not enough, and the glaze of the counterfeit is often very thick;
Second, the real spots are in the pen path, which is a very natural presence in the lines, and the spots have a sense of movement. Fake ones use heavy pens and multiple repetitions, and some double pens are added to double pens.

Su Ma is away from the green fetal bone drill, drilling into the fetal bone is not ordinary.
Not Su Ma also has iron, glaze thickness filtration is too simple.
Su material drill tire is obvious, this is because of iron, if it is crushed, filter the phenomenon of good drill tire is greatly reduced, especially modern process technology, with strong magnetic porcelain glaze to absorb the particulate iron, plus the process and the use of cobalt material is different, so the drill tire is not there.
Rust spots of Yongle blue and white susu material
Domestic and imported cobalt spot identification There are few spots on the domestic black background, and there are fewer reddish spots in the manganese high blue.
The thickness is not the same as the import material, and the black and brown spots should be known.
The black limonite spots have tin light, and the tin light is naturally in front of the eyes.
Blue and white cobalt material is made at high temperature and baked in the kiln in a melting atmosphere.
Ming Xuan De Su material
There are few black-brown spots in domestic materials, because of the high manganese content, blue is reddish;
Imported material iron spots naturally have tin light, blue in the brown, there is a sense of thickness.
Namely: domestic: black brown reddish, poor shade, less spots.
Import: black brown brown, good shade, many spots.
Cobalt material is fired blue in a high-temperature kiln, because the composition of the cobalt material is different, it cannot be imitated successfully, and the imitation is unnatural. (Grilled: 陳钵* meaning, for writing baked characters in rhyme)

The relationship between glaze and fetal markings
Eat tire drill tire spots, so all kinds of things to know.

Condensation spots, spots into the fetal bone, eating tires, drill tires is a meaning, that is, the meaning of cobalt containing iron in the firing process penetrates into the tire, because the different materials of the era are treated differently, so the drill tire has always been regarded as one of the important bases for identifying ancient porcelain.
In the tread appeared spots, and the spots are concave, casual walking, heavy tearing of the tire into the fetal bone, not bulging, this is often said to be su material eating tire phenomenon, and the cleaning accuracy of su material is related to how much iron.
This kind of spot often appears in the two strokes of the pen pressed together and dipped in the glaze more, the pen weight of the ornament, because the glaze contains iron so the color is brown, the genuine spot is natural.
There is also a kind of glaze that is not thick and has no spots, but carefully see the pattern of the pen under the glaze close to the tire, which is called sunken tires, not spots.

There are also many types of drill tires, some are spots, some are strips, some are pits, points, and some are evenly sunk into the tire, which depends on the eyesight, the iron-containing high spots are obvious, the iron-containing less is not obvious, such as the early cobalt material, the grinding is not good, the particles are large, so the spots produced are not so obvious, after grinding into a fine powder, it is evenly sunken, not the pit road, of course, it also depends on the glazing process and what material is used, which kiln mouth is used, which is obviously different. Condensation spots and drill tires (eating tires) are one of the best conditions for generation breakage. (Generally su ma is like cowboy blue in the cloth when it is light and green)
