There is a friend who tells Xiaobian that she bought the jade bracelet five years ago. At that time, she floated a small flower. The small green flowers in the first two days have become bigger. What is going on? How to explain this phenomenon? . First, after research by professionals, it is confirmed that pure sodium spodumene is colorless, and only green chemicals can be added after the addition of chromium chemical reagents. Therefore, the natural jade belt does not have green (or blue), it depends on whether there is "mixed in" chromium inside the jade, and the more the "mixed" chromium, the greener the jade. Second, the amount of chromium contained in the ring or other jewelry processed from jadeite obtained from mines or rivers has been fixed. So the green on the jade cannot be alive. However, in some cases, chromium in jade can produce a chemical reaction, which causes a small amount of diffusion of chromium, which is why people think that green is "long". The jadeite that produces green "long" is mainly jadeite with jade necklace, jade bracelet and jadeite brand that are in close contact with the skin. Third, there is a certain temperature in the human body, and it is easy to sweat. The sweat has acid or alkaline components. These components can penetrate into the microcracks of the jade, and some of the components may chemically react with the green chromium ions. The reaction either dissolves the chromium ions that have been consolidated in the jade and produces migration, which makes the green "long" large. In fact, there is no change in the content of green chromium produced in jade, only trace amounts of chromium are diffused or migrated.
