1, the most important way to identify Bian Shi is to look at the chemical element analysis, which is usually called the test report.

The main component of natural ochre is a mineral called "microcrystalline limestone", in which strontium and calcium oxide are the most abundant, followed by silicon oxide, sodium oxide, aluminum, iron, magnesium, phosphorus and other elements. Trace elements and rare earth elements contain more than 36 kinds of elements beneficial to human body, such as chromium, manganese, nickel, copper and yttrium. The content of sexual substances is very low.

At the same time, some stone materials contain metal substances such as copper and iron, which leads to red, yellow and green colors in stone evaluation.

2. Stone structure of kerbstone

Bian Shi is a pure natural health care tool, which is made of natural four-sided stones by artificial polishing. When it is broken or broken, its broken surface will show the nature of natural stone, and the dense structure of stone can be clearly seen. In addition, the hardness of stone criticizes that stone is fragile, softer and more fragile than ordinary stone, and scratching with hard things will produce obvious marks.

Step 3 look at the gloss

The quadrilateral stone has fine surface, high polishing degree and small particle size, about 0.03 mm In addition, the test report of mineral crystal size should be clearly seen when purchasing.

Judging from the knock on the door.

The sound of Bianshi land in Sibin is more like the sound of metal, clearer and more continuous. Therefore, there is a saying that "the golden sound is jade" and "the beam bends for three days", while the sounds of other stones, such as drums and gongs, are dull and short.

5. From the feeling of touching a stone.

Pseudobian stone is mostly mined ore, which feels cold from the inside out. Tetrahedral stone belongs to surface pumice, which has the characteristics of "fine, clean, warm, moist, greasy and condensed" of gemstones. It also has the characteristics of fast heat absorption and slow heat dissipation, which is also the origin of its use as a hyperthermia tool. Because one of them.

Extended data:

Sibin Bian Shi

Spine stone is mainly composed of microcrystalline limestone, which contains more than 30 kinds of rare earth and trace elements beneficial to human body, such as strontium, titanium, chromium, manganese and zinc. Although the main component of Spine is microcrystalline limestone, microcrystalline limestone is not Spine, so it cannot be generalized when buying it. Some personal testing centers and jewelry appraisal departments can only make a simple stone classification judgment on "Bian Shi", but they can't get detailed chemical element analysis data.
