As the saying goes, "ten seeds and nine cracks", cracking in Hetian jade seed material is very common, popular understanding, cracking is like a scar on the seed material. In the jargon, small cracks are called sputum, and large cracks are called cleavage, which together are called "cracking."
Due to the different formation time and formation reasons, Hetian jade seed material can be divided into several types, such as splitting, dead cracking and skin cracking. Let's take a look at it.
Cracking and cracking:
The cracking of the crack means that the crack is obvious, and the thickness, length and depth of the crack are different. The long and deep meets, the shallow and the middle of the two sides, the jade inside the jade, etc. . Generally, such cracks will have a bleak, and the crack will not be longer, or it will change.
Live cracking refers to deep cracks. If you wear it later or play it through, if you are not careful, it will easily make these cracks develop more seriously. If it is serious, it may break completely. So remind everyone to guard against the existence of this kind of crack in the process of buying.
Old crack and new crack:
Old crack, refers to some cracks that have "slowed slowly" in the natural process. The inside is full of color, and the feeling of touching it can't be felt by hand - it can't be seen. The old cracks are generally shallow, do not extend into the interior of the jade, and the cracks are not large, often characterized by water grass and nail streaks.
The new crack, the formation time is shorter, the crack is generally tender, the color is lighter at the crack, or the color is not obvious. This kind of new crack is generally very vigilant, because we can't see the depth of the crack, if it is deep into the jade, the impact on the material will be great.
Skin cracking:
The skin crack is different from the deep and downward crack that we usually see. Its crack is only on the epidermis, and the direction is left and right. The above are just a few of the different cracks we have. Remind everyone: Death is good, life is difficult to remove. We should try to avoid the occurrence of fissures when buying materials. Relatively speaking, the risk of old cracks is much smaller.
Can the crack of the seed material be used to judge the true and false of the skin color?
Splitting is a very practical way to distinguish between true and false skin color. The color characteristics of the crack on the natural seed material are: from shallow to deep, the color of the crack is deeper than the surrounding color, and the transition is excessive, the transition is natural, and the line is distributed, showing obvious color lines.
Natural: Deep in the dark, the shallower the edge.
The artificially dyed cracks are characterized by a darker edge and a shallower inwardness. This jade natural seed is just the opposite. The color of artificial dyeing is too thick and floating, and the color of the crack is densely distributed along the crack, which is not much different from the surrounding color.
Artificial: the edge is darker, the shallower the inside
In addition, the cracking of the seed material can help us better identify the true and false of the seed material. For example, the common water grass mites at the splitting of the seed material is a means to distinguish the true and false of the seed material. Artificial coloring is a feeling that the water can not be produced.
