When will the beads in the martial arts altar (Su Yuan) not fade?

As we all know, the newly acquired Udan Pearl (Su Yuanzhu) has not been wrapped in a dish. When they rub against cotton cloth, there will be dark red marks on cotton cloth. This is what we often call the fading phenomenon of Udan Zhu (Su Yuanzhu), which is a very normal phenomenon and is often used to identify the authenticity of Udan Zhu (Su Yuanzhu). The main reason is that the ebony pigment of Wutan Fozhu (Suyuan Fozhu) logs is dissolved in water or alcohol and dyed dark red. After drying, the color of the log is still dark red. Wutan Buddha Beads (Suyuan Buddha Beads) were often used as raw materials for dyes in ancient times. Then there are two situations in which Wutanzhu (Suyuanzhu) beads will not fade.

1. After playing for a period of time, the color of Wutanzhu (Suyuanzhu) darkens, and the tube holes with cow hair lines begin to be filled with patina, and the surface will gradually become bright and fluorescent, forming a thin layer of patina on the surface. When Wutanzhu (Suyuanzhu) forms patina and stabilizes, the color will not fade basically.

Second, you will often see some Udan Zhu (Su Yuanzhu) just enough to buy back. Why? The reason for this is the following：

1. It may be that the surface of these Wu Tanzhu (Su Yuanzhu) has been waxed or painted, so the color will not fade when playing;

2. Or the newly bought Wu Tanzhu (Su Yuanzhu) is placed for a period of time, and the surface is highly oxidized by air or has naturally oxidized to form patina, which is not easy or easy to fade;

3. Of course, the possibility of fake Wu Tanzhu (Su Yuanzhu) does not rule out;

However, you don't have to be too nervous when you encounter the phenomenon that the color of Udan Beads (Suyuan Beads) is just enough to buy back. You think you bought a fake, but it may not fade.
