Topaz optimization and degaussing wearing method
Irradiation Most of the blue topaz is irradiated by a colorless topaz and then heat treated to remove yellow and brown. This method of color change is ideal, but inevitably brings an annoying problem, that is, residual radioactivity. The residual radioactive half-life of topaz is approximately 100 days. Therefore, the topaz treated by color change can not be put on the market immediately. The manufacturer generally stores it for more than one year (three more half-life, at this time the topaz has a negligible radioactivity, which can be neglected), so it is factory-elected. Paishi is safe and does not cause harm to the human body. How long it takes to change the color of the blue topaz has been a major concern for the jewelry industry and consumers. Through the fading simulation experiment and exposure to sunlight in the past 5 years, it showed that it only faded by 2%-3%, which means that it could not be seen to be obviously faded within 50 years. 2. Heating Most of the world's topaz is produced in Brazil, and the yellow tintops produced in Central Asia such as Brazil and Pakistan can be pink and red when heated. 3. Coating treatment Colorless topaz can be blue-green, multi-color (like kaleidoscope), red, etc. by PVD surface treatment (Physical Vapor Desposition). The name of topaz is jade but it is actually a kind of spar, so the topaz bracelet is very particular about wearing it. Christianity or Catholics need to be taken with their left hand, not Christian or Catholic. Both hands can be used with the same effect. Topaz belongs to the spar, so it needs to be demagnetized. However, because the orthorhombic system cannot use degaussing methods such as crystal holes and crystal clusters, it is common in collectors to use degaussing or degaussing with sea chrysanthemum. There are two methods for degaussing. One is to mix the fine defensive salt and mineral water and pour it into a cup or bowl, then put the topaz into it. Degaussing can be carried out continuously for 1 month. The second type is to buy a special large-grain defensive salt, which is packed on a plate or a dish. Bury the topaz with defensive salt. This effect is very good, degaussing can be used for 3 months. Also called 100 days degaussing. When the sea chrysanthemum is demagnetized, it is relatively convenient to put the topaz in the center of the sea chrysanthemum after 24 hours.
