2. Combination of dish and brush: When you encounter walnuts with deep texture, you should use a brush to clean them frequently. Just like King Kong, the "three-dish and seven-minute brush" is equally applicable to walnuts. It is recommended to prepare two brushes, one with hard hair and one with soft hair. At the beginning, you can use a hard brush to clean the residue and fruit crumbs, so that the cleaning effect will be better.
3. Anti-blooming point: When oiling or cleaning the nuclear carving, first drop a few drops of oil on the brown brush, and then brush it again with a brown brush that does not drop oil, so as to disperse the oil accumulated in the deep recess. Finally, use a cotton soft cloth or paper towel to blot up the accumulated oil.
Extended data:
Note the following:
First, anti-cracking
Cracking is a common phenomenon in nuclear carving. The principle of cracking is that the humidity inside and outside the core is not uniform. The air humidity in the nuclear and the humidity outside the nuclear should be kept in balance. If there is a big difference between the high inside and the low outside, the humidity inside the nuclear will expand outward, and the surface of the nuclear will shrink inward when it is dry, and it will crack. Nuclear carving crafts cannot be exposed to the sun, soaked in water and blown by the wind for a long time.
Second, oiling
Because the kernel itself contains a lot of oil, but with the passage of time, the oil will dissipate, so it must be oiled to enhance its oil quality. If there is less oil, it will be easy to crack. If it is oiled on the surface, it will blend into the interior. If it is smeared evenly, the whole kernel can absorb oil.
The method of oiling is: dip a soft brush in a little light-colored oil (olive oil, peanut oil, salad oil, soybean oil), first brush a few times on any instrument to let the oil flow evenly on the bristles, and then you can carve it on the Korean nuclear and fill it with oil.
