But this process is very slow, and it takes time to precipitate. The purpose of plate play is not only to increase the temperature of wood and accelerate the secretion of oil, but also to polish and polish the surface of beads to make them smoother and more delicate. The smoother the surface of the beads, the more oil secreted by the beads can stay on the surface of the beads instead of being taken away by tools.
The color of the new string of lobular rosewood is orange red. After wearing it on your hands, the color will gradually darken, and there will be a slight dyeing phenomenon in the early stage of contact with hand temperature, which is purely normal. The surface in contact with air is oxidized.
Directly using the hand plate will accelerate the secretion of oil, but it will also make the beads lose their luster and look greasy. The oil and sweat secreted by the human body make the beads black.
After playing with patina, the surface reappears luster. For the old rosewood with good oiliness, fine texture and few brown eyes, after a long period of oxidative friction, a layer of substance similar to amber texture will appear. Play with it repeatedly, the beads will have aura luster, and the good beads on the plate will have a layer of glass luster, three points. This is the glass bottom patina of lobular rosewood.
