Tang Sancai's identification skills
First, look at the quality of the fetus. Judging from the unearthed situation, Henan Luoyang Gongxian kiln three color authentic products are mostly white ceramic tires, the tire quality is fine, loose, white and red, is a powdered tire. Another kind of hard quality is hard, white is blue, and the sound is clear, it is a steel tire.
Observe the genuine porcelain with a magnifying glass. The wound can be seen. The fetal material contains a small amount of black impurity sand. If the genuine tire part is put into the water, it will appear moderately pink when taken out. If the dirty soil is cleaned with a brush, there will be a lot of sandy pits in the real part of the tire. The imitation of the tire is fine and white or gray, and the hardness is large. When the tire is placed in the water, the soil is white, and the smell of coal smoke and sulfuric acid can be smelled.
Second, look at the shape. Ancient artisans often used ceramics for a long time. They were skilled and free-spirited. The artifacts were simple and vivid, with rough and uneven thickness. The imitations are quite similar in shape, size and size, but the shape is stiff, and the overall and local proportions are not harmonious. Horses, camels, scorpions, etc. have cutting marks around the bottom of the objects, which are too regular and give a deliberate creation. The feeling is that the interior of the object is too white, there is no rust and natural dust.
Third, look at the glaze color. Collectors generally identify the authenticity of the authenticity is that whether the real thing, whether it is glaze or spot glaze, flowing natural, the color is bright and shiny, the glaze has a soft luster, commonly known as "Baoguang", some glazed white silver. After washing with water, a bright luster will appear, and when it is dry, white silver will be exposed immediately.
The imitation glaze is dazzling and glaring. When viewed from the fluorescent lamp, the glazed surface will appear purple, golden yellow and bright green. The white silver on the glaze will rarely appear after washing. It is the reaction that occurs after sulfuric acid has been corroded. How to identify Tang Sancai, this method is the most intuitive.
Fourth, look at the pattern. The real thing is observed with a magnifying glass, and a colorless fine-grained piece can be seen. The large piece is basically uniform, and the periphery of the piece is slightly uplifted. Most of the lines are developed from left to right, and the lines are short and staggered. The replica pattern is large, there is no uplifting, and the lines are mostly developed from top to bottom, and the lines are long and straight.
Fifth, smell the smell. The smell of the real thing is similar to that of earthworms. It can be smelled in a foot of water. We call it a burial gas. The authenticity is eroded by hundreds of years or thousands of years of slow soil and corpses. Absorbed.
The imitation product can smell a soot after passing through the water, which is the soot gas when the kiln is burned. In recent years, several imitation masters have achieved the effect of burial. They used pesticide sixty-six powder water to etch pottery tires in order to achieve the funeral effect.
Six, look at the soil rust. After the surface and interior of the authentic product have been etched by hundreds of years of water and soil, there are many iron-red spots on the inside of the tri-color object, which are neat and orderly.
