Identify true and false

There are not a few fake white marbles. How can we tell the truth? In fact, only one light and three words are needed. A ray of light is the most common light or sunlight. It is the most important way to identify white marble. The three characters are the words "Han", "White" and "Jade". The word "玉" tells the characteristics of white marble. In fact, white marble is not a jade, but a kind of marble. The reason why it is named after jade is that it is shiny and shiny, and the thin places can pass through the light. The word "white" means that its whiteness is dazzling enough, enough to shine, and it can turn to the sun and achieve the effect of Venus.

The most important thing is this "Han" word. But this "Han" turned out to be a typo. The "Han" of the white marble should have been the "sweat" of sweating. The word "Khan" represents one of the most unknown features of white marble: the real white marble is not white, but implies a shallow texture, just like the impression of sweat. With these three standards, on a sunny day, if you are walking around the Forbidden City, you will find that there are few ancient buildings that meet these standards.

The current technology is developed, and some so-called white marble also meet the above three criteria, but they are also fake, because they are suppressed with stone powder. How to identify it? One of the major flaws of white marble is the beneficial weapon of counterfeiting. Observing the carvings of white marble, you will find a feature: whether it is a lion, a Chinese watch, or a pillar or railing, no matter how beautiful, there will never be a hollow ornament. This is not the white marble jade master is not as good as people, but because of its own defects.

Although the white marble is relatively hard, but it is fragile and fragile, the carving of the white marble has a scientific name called “stick shape”. For example, it is necessary to sculpt a Guan Gong statue holding a Qinglong 偃 刀 knife. If it is wood carving or clay sculpture, the knife and the body must be separated. If you use white marble to sculpt, this shank must be close to the body, so that the white marble that is thinly carved will not be able to work hard. Thus, the whole person is like a stick, there is no gap in the middle.

Nowadays, the white marble statues made by many merchants on the market are made of stone powder, or they are carved from soft stones and impersonated white marble. Stones of this type do not have the Achilles heel of the white marble, so they can make a variety of complex hollow shapes. But these tricks that add to the snakes are precisely the most obvious flaws.

Specific identification

Identification of the quality of white marble stone, divided by grade, generally divided into first, second, third, fourth, good, secondary stone difference is very large, mainly to detect its density and purity, white marble is white The finest in marble, it has its own veins, it does not produce white marble, it produces white marble. Don't misunderstand the place of origin. There are also great differences in the texture of white marble. The same vein, the stones extracted from different mining areas are very big. The difference is that the stone mined in the same mining area is divided into good levels and bad levels. Each level of stone is also different. There are hardness, color, texture cracks, iron blocks, iron wires, etc. It is said that it is very different.

In addition, depending on the weathering period, the natural formation of the white marble deposit has obstacles to the white marble carving, which makes the processing and production have limitations. This is also a problem that needs to be considered in engineering design.

Excellent white marble stone with fine texture and high hardness can engrave good works. According to the construction materials, it can be weathered for thousands of years. The secondary materials are different. The weathering age is earlier, the long decades, the short In the past few years, some even weathered in the past, and in the past few years, there have been cracking of stone layers. Especially ordinary white stone, produced in many places, the quality is very different, after making the finished product, it is more difficult to identify the quality of its material.

White marble is in great demand for architectural decoration. It is a limited amount of stone for mining in the country. Some projects use one-grade white marble, some do not. Other white stones are also more suitable. They can also be used in architectural decoration, but they must be used. If you choose materials, you can make good projects and good works with less money.
