Wrapping pulp and hanging porcelain are both the expression of playing walnuts.

Pulp: wrapped in a layer of pulp. The pulp of the walnut, indeed, from the surface of this layer of pulp gradually evolved.

From the walnut into the hand to play a few months to a few years, walnut pulp will become deeper and deeper, the area will also be with the walnut surface wear and tear and increase. Deep into the wood of the deep constituents because most of the lipids, so show "oil" characteristics, will be accompanied by "respiration" deep inside the walnut, and finally into the walnut cavity, and walnut kernel encounter.

If at this time the walnut kernel happens to be in the state of internal moisture completely exudes clean, encountered the lipid material will be quickly mingled with it, kernel oil continues to ooze out, along with the disk kneading and rotating process all over the surface of the inner cavity, but also by the "respiratory effect" of the influence of the reverse outward penetration, and further integrity, perfect the lipid material! The fusion with the wood, quietly change the composition of the wood.

Hanging porcelain: bring a pair of children playing decades and even hundreds of years of old walnuts, its body pulp warm and moist as jade, cool to the touch. Touch each other when issued a crisp, bright sound, such as two porcelain touch. This state of the old walnut, known as hanging porcelain walnut. Hanging porcelain is an upgraded version of the pulp.

Hanging porcelain can be regarded as a hardened pulp, which is fundamentally different from the state of pulp is that hanging porcelain is more stable, will not be softened by the addition of a new creamy sebum film.

Extended information:

Transformation process of the pulp to the hanging of the porcelain:

As the sebum mixture precipitated wax crystallization of the physical state of the pulp is also There is a great deal of instability. Initial pulp, in the process of further play, the new addition of milky sebum film will gradually soften the pulp, the walnut surface will feel "sticky", "greasy", which is a normal phenomenon.

With the passage of time, the walnut surface texture gradually wear, the palm of the hand can touch the surface area increases, the surface of the wax precipitates with the long years of disk play continue to experience: extrusion, solidification, extrusion, solidification process.

The intermolecular moisture is gradually lost, the degree of solidification is intensified, the whole walnut body pulp, the depth of the degree of "into the wood three points" point. At this point, the walnut can be called "hanging porcelain walnut".
