A skill of choosing a walnut bomb. First of all, the texture must be particularly deep. Secondly, select immature walnuts, about 70-80% mature, and find two walnuts with the same size, pattern, volume and even weight. After decades of playing, the color of walnuts can change from light to dark and finally to old red. Nowadays, some collectors still collect some strange-looking walnuts.

Because of the different texture and structure of walnuts, it takes different time. If it is summer and there are more hand secretions, the time required for each stage of "four rubs" may be shortened. In addition, I think we should rub our hands separately and adopt various methods, so that the coloring speed, moistening degree, patina and magnetic hanging time of playing walnuts will be faster.

Brightening stage: When the walnut is mature, it should generally be the natural color of the walnut itself-dark brown (commonly known as white stubble). Except for the fake, the color is similar to that of edible walnut skin. Of course, different varieties of walnuts also have darker or lighter colors. At this time, when you start playing, you will enter the stage of rubbing. At this stage, you will feel that walnuts bite your hands, which is also the hardest stage for all nuclear friends. You will feel that your hands have become rough and have no sense of accomplishment. Because there is nothing in the walnut skin at this stage, it will absorb the sweat and oil on your hands. At this stage, the only thing we have to do is to rub the sweat and oil from our hands into the walnut skin, penetrate into the Lippi of the walnut through the skin, and rub it repeatedly to brighten it. How long is the stage on? This depends on how long you play every day, how hard you pinch it, how much sweat and oil your hands secrete, the variety of walnuts and the climate. Take me as an example. Lionhead dogs play at least 10 hours a day, one in each hand, rubbing, pinching, pressing, pricking, pinching, rubbing, etc. And the friction strength is relatively strong. I'm a sweaty hand, and it takes about a month and a half to shine. Please click to enter the picture description. 2. Rubbing red stage: The walnut that just got off the tree feels heavy in your hand (commonly known as: beater), and the wooden structure is loose and soft. With our constant play, the sweat and oil on our hands rub against the skin of walnuts, and the water of walnuts evaporates and gradually replaces it into our body fluids, finally reaching a basically saturated state. After playing and rubbing for a long time, the texture of walnut itself will change, the water will evaporate, the volume will shrink, the weight will be slightly lighter, and the wood will gradually harden. At this time, if you look closely, you will find that the baby's appearance in your hand is quietly changing and gradually turning red, which is the performance of starting sizing. The baby in your hand will naturally reach the level of patina when we play. At this time, compared with a very different new walnut, you will have a great sense of accomplishment and have a lot of fun. In the process of playing, the amount and temperature of palm secretions will have different degrees of differences on the evolution of color. The more secretion, the higher the temperature, the faster the color is finished and the stronger the color is. Through "rubbing" and "rubbing", sometimes the bright red phenomenon can be reflected at the same time. The red rubbing stage is a process from sizing to wrapping. How long will this stage take? Take myself as an example, it will take about three to six months to reach the level of initial sizing by keeping the time and method of playing unchanged.
