Brush a thin layer of baby oil sealed bag, don't blow it for the first three months, and don't get wet. Keep away from heat sources and avoid sudden cooling and heating. We must pay attention to the above points in the first three months. Brush the oil seal at the beginning of winter to adapt the core to the surrounding circles. The simple way is to wrap it in a wet towel. In a day or so, it will generally heal naturally. In addition, according to my own experience and the maintenance method of lobular rosewood cracking, I put it in a sealed bag and put some water in it to crack.
There are two views about the cracked thing: 1. It doesn't matter, everything happens. No matter how cracked it is, it won't split in half. When you play the patina beautifully, the cracks on it are basically less obvious. Even if it is obvious, it is too expensive to buy. At least do your homework and have fun! Personal suggestion: give up after a few days! Don't wait for a long time to play, you will always remember that crack, which will affect your fun. Buy a new one and play again, it will crack! After the patina is finished, it will be invisible or very light! Remember that the cracked one is kept in the refrigerator alone! After repair, just press the new core for maintenance. Never take out the new core without patina, for fear of wind and temperature difference is much more terrible! The northern greenhouse.
