Hetian Yangzhi white jade maintenance:

1. Avoid bumping with hard objects. The jade is easily broken after being hit. Sometimes the naked eye does not see cracks, but the molecular structure in the jade surface has been damaged, resulting in dark cracks, which will appear for a long time, greatly impairing its perfection and collection value.

2. Avoid dust and oil as much as possible. If there is dust on the surface of the jade, it should be cleaned with a soft brush; if dirt or oil stains are attached to the jade surface, it can be washed with warm soapy water and then washed with water. Never use chemical degreasers. For the heavily contaminated old jade, professional companies that produce and clean jade can use professional ultrasonic cleaning and maintenance.

3. Jade pendants should be placed when not in use. It is best to put them in jewelry bags or jewelry boxes to avoid bruises.

4. Avoid contact with perfumes, chemicals, soap or human sweat. Because the jade is exposed to too much sweat, it will be eroded and the outer layer will be damaged, affecting the original vividness. Jade, sheep fat white jade, more avoid sweat and grease, after wearing, wipe with a soft cloth.

5. Avoid direct sunlight for long periods of time. Jade sun exposure will explode when heated, and the molecular volume will increase, which will affect jade. In particular, crystals, agates, etc. are subject to high heat and burst, so it is more difficult to approach the heat source.

6. An environment that is too dry tends to evaporate water, thereby damaging the quality of jade.

Hetian sheep fat white jade identification method:

The white fat jade is the gem-quality raw material of Hetian jade. It is the best of white jade in pure white color. It has the best brilliance and texture. It is characterized by warm and firm, pure and pure, snow-white and flawless, just like gelatin, hence the name. Looking at this jade and ordinary white jade, the easiest way to distinguish is to watch under the white fluorescent light. The sheep white jade is facing the fluorescent lamp, which is pure white and translucent, with a powdery mist. The usual white jade is translucent to the fluorescent lamp, but it has no powdery sensation. The biggest difference between the two is that the white jade is white in appearance regardless of the grade, but it must have a slight yellowish color under the white fluorescent lamp. Therefore, if there is a slight yellowish color under the fluorescent lamp, it will not be called It is a white jade. The rare and precious sheep fat jade that meets the stringent standards is absolutely inconspicuous. The difference between sheep fat jade

It is necessary to meet five aspects, namely, pure texture, fine structure, water head, color sheep fat white, oily heavy quality pure - the mineral content of tremolite in sheep fat jade reaches 99%. Sheep fat jade exists in the most complete area of ​​wall rock alteration. When the granodiorite and the dolomite war occurred a series of war metamorphic rocks, the dolomite became dolomite marble, and the late magmatic hydrothermal fluid along the dolomite marble structure fissure channel, resulting in the formation of tremolite. The surrounding rock erosion is transformed into three kinds of lithofacies of dolomite marble-tunnelized petrochemical dolomite marble-metamorphic rock, and the sheep fat jade is found in the tremolite rock facies. The structure is fine--the tremolite in the sheep fat jade is microfibrillar crystallized and aggregated. The crystallite size of the tremolite can be measured under electron microscope and optical microscope, and the tremolite fiber length in the sheep fat jade ( The longitudinal direction is 0.033-0.01 mm, and the width (transverse direction) is 0.0006-0.001 mm. These microscopic, fluffy, felt-like tremolite crystals are intertwined to form a pile-like structure, a felt-like structure, and a staggered structure. Microfibrillar, fluffy, felt-like tremolite crystal aggregates, under orthogonal polarization, are characterized by a uniform matte appearance at similar angles. Water head foot - water head, spirit land are the name of jade transparency, in tremolite jade often from the thickness of 2mm as the standard, white jade in this standard appears translucent - opaque, the head of the sheep fat jade clarified the appearance of translucent. Color sheep fat white - sheep fat white is not pure white, but with a white glow of oil, some in white can reveal a slight yellow, poor texture can also reveal a slight light gray tone in white. Oily weight - the fat touch of the sheep fat jade in the palm of the hand, of course, a kind of oily sexy appearance in the appearance of jade, also in some Hetian fine white jade, when the sheep fat jade falls in the water, mention Jade body, can be dripping water is not sticky, so the oily heavy sheep fat jade is also very good, so-called cotton, it is also toughness.
