At present, the most imitation of the market should be regarded as tea crystal, and most people can't detect anything with the naked eye.
Many of the tea crystals on the market are white crystals or light-colored tea crystals after radiation treatment. However, it can be affirmed that the crystals of the crystals and the white crystals after irradiation are relatively dark and very transparent. In the absence of dendritic silver and rutile or other mineral inclusions, it is generally not recommended to purchase. Friends can go and see that most people who do crystal industry don't wear tea crystals, because they can't know what white crystals are used for artificial radiation. Even with radium, what is the ratio of radium? If the radioactive material is excessive, it is undoubtedly harmful to the human body. The crystal is added during the manufacturing process to change the color.
The method of distinguishing between true and false tea crystals:
1. Plastic products can be distinguished from the touch, temperature and hardness of the hand.
2, glass products, this one is clear as water, no texture, and low hardness, single refractive index, mixed with bubbles, is also very well resolved, can be distinguished by a polarizer.
3, smelting crystal, continental products, like glass, but more than seven, eight centimeters to ten centimeters in size, very beautiful, but single refractive index, low hardness, can be distinguished by polarizers.
4, crystal glass, in fact, is lead glass, glass products with lead metal, the most on the market, because the refractive index, color 28 crystal shopping network is good, it looks dazzling, dazzling, most suitable for decoration, decoration, but Not suitable for spiritual use. Generally, it can be judged by visual observation.
5, artificial piezoelectric crystal, also known as crystal, the original stone does not have hexagonal crystal, which is the easiest place to judge; but if it is ground into a finished product, it is not easy to discriminate by the above method, must be resolved by means of ultraviolet spectrometer True and false, of course, for professional stores, it is easy to distinguish by the naked eye. The most colorless transparent citrine, ametrine, amethyst, and aqua blue crystal counterfeit on the market.
The color of the tea crystal is more transparent and beautiful, and it is pleasing to the eye. But don't be fooled by the fake tea crystal.
