How to identify white marble? How to identify white marble
There are not a few fake white marble jade, how can we distinguish the authenticity? In fact, only a ray of light and a three-character formula are needed. A ray of light is the most common light or sunlight, and it is the most important way to identify whether it is white marble. And the three-character formula is the three words "Han", "Bai" and "Yu". The word "jade" tells the characteristics of white marble. In fact, white marble is not jade, but a kind of marble. The reason why it is named after jade is because it is shiny and shiny, and light can be transmitted through thin places. The word "white" refers to its white enough to be dazzling and shiny enough. When it turns against the sun, it can achieve the effect of full eyes of gold stars.
The most important thing is the word "Han". But this "Han" turned out to be a typo. The "Han" of white marble was originally supposed to be the "sweat" of sweating. The word "sweat" represents one of the least known characteristics of white marble: the real white marble is not white and flawless, but contains shallow lines, just like the mark of sweating. Using these three standards, on a sunny day, those who are interested in walking around the Forbidden City will find that there are very few ancient buildings that meet these standards.
Nowadays, technology is advanced, and some so-called white marble also meets the above three criteria, but they are also fake because they are pressed with stone powder. So how to identify them? One of the major flaws of white marble is a favorable weapon for combating counterfeiting. Looking at the carving of white marble, you will find a characteristic: whether it is a lion, a watch, or a pillar or a railing, no matter how exquisite, there is never a hollow decoration. This is not because the carving master of white marble is inferior to others, but because of its own defects.
Although the texture of white marble is relatively hard, it is fragile and fragile, so the carving of white marble has a scientific name called "mallet shape". For example, if you want to carve a Guan Gong statue holding a Qinglong Yanyue knife, if it is a wood carving or clay sculpture, the knife and the body must be separated. If you use white marble to carve, the hilt must be close to the body, so as not to make the carving thin white marble difficult. Therefore, the whole person is like a mallet, and there is no gap in the middle.
Nowadays, many white marble statues made by merchants in the market are made of stone powder pressed materials, or carved from soft stones, posing as white marble. Stones of this material do not have the fatal weakness of white marble, so they can make various complex hollow shapes. But these superfluous tricks have become the most obvious flaws.
To identify the quality of white marble stone, use grades to divide it, generally divided into first-level, second-level, third-level, and fourth-level. Good, secondary stone quality varies greatly, mainly testing its density and purity. White marble is a fine product in white marble. It has its own ore veins, and it does not produce white stone to produce white marble. Don't mistake the origin. White marble also has great differences in texture. The same ore vein and the stones mined in different mining areas are very different. The stones mined in the same mining area are divided into good levels and bad levels. Each level of stone quality is also different, and there are different hardness, color, texture cracks, iron blocks, iron wires, etc. It can be said that there are thousands of differences. In addition, it also depends on the weathering age. The natural formation of marble deposits poses obstacles to marble carving, limiting processing and production. This is also a problem that needs to be considered in engineering design.
Excellent white marble stone with fine texture and high hardness can be carved into good works. According to the construction materials, it can be weathered for thousands of years. For secondary materials, ordinary white marble is different. The weathering age is earlier, with a long period of decades, a short period of years, some even weathered in the same year, and some have cracked stone lines in just a few years. Especially ordinary white stone, produced in many places, the quality is very different. After making the finished product, it is more inconvenient to identify the quality of its material.
White marble is under construction. Decoration is in great demand, and it is a limited amount of stone mined by the state. Some projects specify the use of first-class white marble, while others do not need it. Other white stones are also more refined and can also be used in building decoration, but you must choose the right materials, so that you can spend less money to make good projects and good works.
