If rosewood wants to be beautiful, it must be put in fewer plates and more. Please see the following for details:
First of all, let's talk about what patina is. Metal, jade and wood can all be patinated, but different things can be patinated differently. As far as the patina of wood is concerned, it is a transparent skin formed by the oil precipitated by rosewood itself and air oxidation, and its thickness is very thin. The patina of wood products is different from walnut and olive. It depends on the oiliness of the wood itself, not the oil or other things added externally. Mahogany, Huang Huali and other wood products will turn black when they see oil, water and sweat! The heavier ones will crack. Man-made oil or sweat on his hands accumulates on the wood, which is not patina, but a layer of opaque smelly sludge.
It is a normal oxidation phenomenon that the color of rosewood board becomes darker after being played/placed for a period of time. It's like you cut an apple, and the new section is white, but after leaving it in the air for a period of time, the color of the section begins to darken. It is right that the color of rosewood changes from black to dark. The better the oiliness, the faster the oxidation and blackening of rosewood. If you want to look good, don't play directly with your hands, play through cotton cloth or wear sheepskin gloves. Vegetables are transparent purplish red in the sun and almost black when the light is insufficient. It looks transparent rather than dirty. )
It should be noted that the patina of wood products is a transparent oxide scale formed by the grease precipitated by itself, which is afraid of foreign oil, water and sweat. Therefore, it is generally recommended to play with suede/cotton glove tray or suede/cotton bag tray.
If the bracelet is rubbed too hard or too hard, the oil just judged will be removed before it solidifies, and naturally it will not shine. Then the disk is played for too long, and the sweat passes through the gloves, causing the beads to turn black!
The intensity of the dishes should be moderate, not too frequent. Otherwise, if you just put a little before the oil is oxidized and fixed, it will be a loss again. Therefore, it is ok to pick it up and play it gently. The time at a time should not be too long, just 0.5-2 hours, depending on the actual situation of the individual (personal advice 1 hour or so). Leave it for two days. Let it fully and naturally precipitate grease, naturally oxidize and fix the mobile phone. Store away from light, and don't put it in an excessively ventilated place to prevent cracking. )
For the discarded beads (the surface is soaked with dirt such as sweat and sludge), you can only find a professional to polish them step by step from 240 mesh to 2000 mesh (up to 3000 mesh or 5000 mesh according to everyone's preference), and the plates will not come back.
The patina doesn't last for 3-5 days or 3-5 months. It takes years of unremitting efforts of science to achieve good results. Therefore, this is self-cultivation, and patina is urgent.
Regarding the identification of rosewood, it is extremely unscientific to draw traces on white paper with online rumors, and it is meaningless to draw traces on white paper to distinguish between true and false. Whether you can draw traces on white paper has nothing to do with rosewood or other wood. Whether you can draw traces on white paper depends on removing pigments from wood. It's like saying that watermelon juice is red and tomato juice is red. You can't say it's all tomato juice or watermelon juice just by color, can you? What is the reason?
In addition, if the surface of the object has been stained and a layer of sludge or other dirt is attached to it, then when you draw on paper, it is the dirt on the paper that comes into direct contact with it, not the wood itself, and naturally you can't draw colors. What can be painted is not necessarily rosewood, and what cannot be painted is not necessarily not.
Red sandalwood, blood sandalwood, acid branches and many other dark red rosewood can be used, but only if a clean new contact surface is needed!
No matter whether the real rosewood is good or bad, there is one thing that fakes can't imitate, and that is the sandalwood smell of rosewood.
The best way to confirm whether it is rosewood is to smell it. Sandalwood rosewood, commonly known as Indian lobular rosewood, has a faint sandalwood flavor, sweet taste, pleasant fragrance, no smoke, no choking, and no discomfort. And fakes are either tasteless or messy, which makes people uncomfortable. It tastes like chocolate, but it smells different subjectively. )
Of course, there is a premise to smell. The smell of things that have been processed for a long time almost disappears, and only the obvious smell of cutting or latest processing can be smelled. If you want to ask the taste of the finished product, you need to seal it and heat it before opening it, so that you can smell the faint volatile smell.
I hope it will help you.
