Yangzhiyu maintenance knowledge:

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.
