Pear wood contains a special substance melanin, which is easily oxidized and discolored in the air. Pear wood, because there is bark outside, and there is a layer of white skin inside the bark, double protection can effectively prevent melanin in the trunk from contacting the air. Therefore, the pear wood is very authentic orange before processing, and the color is bright, which is why the surface color of the pear wood bead bracelet just coming out of the bead processing workshop is so red and bright. However, after leaving the factory, the pear flower beads will inevitably be oxidized because their surfaces are completely exposed to the air, and their colors will gradually darken as time goes by. This change is obvious. Generally, new beads will turn black about a month after leaving the factory.
Tips:
The so-called black pear beads are not a quality problem, but the characteristics of pear wood.
