Anyone who knows about bian stone should know that the real April bian stone has a good health care effect on human body, but there are a lot of fake bian stone on the market. Here are some simple ways to identify the real April Stone, so as not to be deceived.
First, look at the stone structure in Bian Shi.
Bian Shi is a pure natural health care tool, which is made by hand from natural four Lunatone. When it is broken or crushed, its fracture surface will show the true color of natural stone, and the dense structure of stone can be clearly seen.
The picture shows the broken kerbstone: the pumice structure in Sibin is clear.
The stone used to make mounds is relatively weak in hardness, softer and more fragile than ordinary stones. Scratching with a hard object will produce clear marks.
Second, judging from the gloss of the kerbstone surface.
The original stone of genuine kerbstone is Sibin Pumice (Lunatone), which is grayish black after pure hand polishing, and will turn black and shiny after long-term absorption of human body oil, and it is a black beautiful stone. At present, the stones used in hospitals and scientific research institutions are all black four-shore pumice (four-Lunatone), and no stones of other colors have been tested in clinic and scientific research. It is unscientific to distinguish the true and false of bian stone simply by the color of bian stone, which is entirely the personal speculation of some vendors.
Surface comparison of plastic pseudo-bian stone and true April bian stone
As can be seen from the above picture, the plastic pseudo-bian stone is bright and light, which is obviously different from the natural luster of the real bian stone.
Third, judging from the feeling of touching the stone.
Pseudo-bian stone is mostly made from ore obtained by mining, and the feeling in hand is cold from the inside out; The pumice in Sibin (Lunatone) belongs to the surface pumice, which has the characteristics of "fine, clean, warm, moist, greasy and coagulated", and has the characteristics of fast heat absorption and slow heat dissipation, which is one of the reasons why it can be used as a hyperthermia tool.
In addition, because the pumice in Sibin (Four Lunatone) is micrite limestone structure, it can be obviously felt that its surface is smooth and soft when touching the real stone, and its fineness is ten times that of jadeite.
Fourth, judging from the sound.
The pumice stone in Sibin (Lunatone IV) is more like the sound of metal, more crisp and continuous, so the sound of gold is like jade, and the sound of other stones is like the sound of gongs and drums, which is dull and short-lasting.
