As the price of turquoise has risen year after year, the treatment of artificial fraud has also emerged in an endless stream. Recently, the circle has spread a simple method of distinguishing the true and false of turquoise: soaking the turquoise with water, if it will change color, then it is false, this method is true. Is it reliable, today Xiaobian will tell you something about it:
The four main types of fraud on turquoise:
1. Silicone rubber - soak the turquoise in the gel
2, injection glue - through the vacuum pressure, the glue into the turquoise
3, dyeing - dye the white pine stone into a turquoise look
4, powder pressure - other materials or with turquoise particles granulated into a turquoise look
Looking at the above counterfeiting means, it is obvious that the first two only increase the density of turquoise to a certain extent, which is an optimization effect. The latter two are purely fake.
As fraudulent means continue to innovate and the craftsmanship is becoming more and more sophisticated, it can only be discerned by professional instruments. Professional instruments are not owned by everyone, and they cannot be taken anywhere. Even people who have been in the industry for many years are difficult. Just look at the picture to tell if the turquoise is processed. With the rumors that the flooding can be identified at the beginning, many people are very happy. Xiaobian must tell everyone that this method is really unreliable. The reasons are as follows:
If the loose stone itself is loose in texture, it is easy to absorb water and discolor, and the high quality pine stone is not sensitive to water due to its tight texture, and it will not change color. As for the fake turquoise, it will not change color after treatment, so it is difficult to judge by this. .
Identification recommendations:
1, look
In addition to seeing whether the iron wire is uniform or not, it depends on the texture. The most typical characteristic of the fake turquoise is the porcelain grain pattern. The so-called porcelain grain pattern literally means a small crack formed by the fired open porcelain. It looks good, but it is fake.
2, touch
Turquoise is highly absorbent, so it will feel sticky when touched, but it won't be too sticky. If you feel the touch and feel the same as the double-sided adhesive, then the explanation is that the glue is glued.
Finally, it is still recommended that when you buy turquoise, you can choose some merchants with high reputation, or those that you trust more, especially those with higher value, or send inspections, let professional identification agencies check for you. It is more secure.
