1.Permeability performance
The natural jade has excellent permeability. The better jade has flexible and natural visual sense, but natural jade is formed through the geological movement. So it exists in the place with uneven distribution of ray although it is pervious to light with natural cracks and flaws and not uniform visual effect. In the aspect of home decoration, large-area use will influence the visual effect. Queen Longjade is calcinated by burning simulating the forming process of natural jade without existence of complex and unordered textures, so the overall Permeability performance is very even and nature. The ray is reflected inside, which is warm and fine.

2.Ardness and wear resistance
Natural jade Mohs hardness is only 3-4. The surface is easy to be worn when used in the ground for long time. The Moh's hardness of Queen Longjade may reach 6-7. The product is inserted “Super hard jade molecule” element. After several times of refining and hard throwing, the product is wear-resisting and not easy to produce marks.

3.Impact resistance
The natural jade has cracks and is easy to break due to the factor of generating environment. The loss rate in the processing link is very high and the loss is very high in the decoration process. Queen Longjade is burnt in the high-temperature physical conditions with hard texture and good toughness. It is suitable to the business space, hotel and other places with high passenger flow.

4.Folding degree
Natural jade is easy to break. Especially as for the large plate, it should be glued and fixed timely and open groove and add steel strip, causing more trouble in the transportation, installation and paving process. After High temperature and slow burning process at 1500°, the hardness of Queen Longjade is far larger than the former. The product is characterized by high density, stable physical performance, not influenced by expansion caused by heat and contraction caused by cold, no deformation and no cracking.

5.Pollution resistance
Natural jade is mainly formed by the deposition of minerals with more surface cracks, tiny holes, easy to permeate and easy to go dirty. The dirt in daily life is easy to e seeped inside. The surface is clean and cannot be removed with expensive curing price, time consuming. Long-time use and non-maintenance will cause saltpetering. Queen Longjade will not permeate any dirt after High temperature calcination and fine polishing process. Therefore, no matter how long it is used, the surface will keep smooth and bright. It is easy and convenient to clean.

6.Water absorption
The natural attributes of natural jade cause more tiny holes and fissures on the surface of jade stone. The water absorption rate is quiet high in addition to dirt. It is the cause that the jade cannot be cleaned with water. Queen Longjade is high in density. The surface has no tiny holes and the water absorption rate is nearly 0. Therefore, it may be directly wiped with water.

7.Color difference
Natural jade leads to the surface texture of the jade larger color, root crack, more defects because of its natural property. It is easy to change color under UV irradiation. Common natural jade will pass the glue and dyeing treatment. Queen Longjade uses the core technology of Tsinghua University with Scientific formula of natural mineral raw materials and quartz sand. After modern specialized equipment production, the change of the texture and the production process is accurate and controllable. The finished product has no defects, no color difference, no color fading.

8.Post nursing
Natural jade surface requires regular polishing, waxing and other maintenance work after paving ground due to Pore and root crack, which is time and labor consuming. With high density, Queen Longjade is bright and wear-proof on surface after three times of fine processing and hard blotting. It does not leak water. The daily maintenance is very simple.

9.Generation process
Natural jade is the original rock in the earth's crust formed by high temperature and high pressure in the earth's crust with excessive mining and simple processing. Due to the product phase and Nonrenewable mineral resources and instable supply, there is serious color difference in the replenishment. The rate of stone material is low, and the environment is broken. Queen Longjade is in the principle of formation process of natural jade is simulated by scientific and modern equipment. It is burnt through 380m furnace, excluding radioactive mineral elements. It is more healthy and environmental protection and meets the supply demand and makes up various problems occurred from the constraints of natural formation conditions.

10.Cost performance and practicality
A thing is valued if it is rare since ancient time. Natural jade is usually expensive because of its nonrenewable natural conditions. However, it saves time and materials in the use cycle of home decoration materials and art work. The drivability is far less than Queen Longjade. Due to the difference in physical properties, Queen Longjade may play effect in different fields, which makes up the insufficiency of natural jade in the application value. The cost performance is Remarkable
