Red jasper is a kind of Hotan jade. It is a chalcedony with many impurities. It is a nephrite formed after serpentine intrusions into basic volcanic rocks and other surrounding rocks. The content of iron oxide, clay minerals and other impurities can reach more than 20%. It is opaque, and its color is mostly dark red, green or variegated.
It is good for red jasper to soak in water occasionally, but it is better not to soak in water for a long time. Red jasper is composed of tremolite, which is a kind of hydrate. Although it will lose crystal water if dried for a long time, and the jade quality will be damaged, tremolite is a relatively stable material. The wetness of personal wear is enough to meet the water demand of Hotan red jasper, and it is unnecessary to soak in water.
When wearing ruby, try to avoid contact with perfume, chemical solution, soap and human sweat. As we all know, sweat contains salts, volatile fatty acids, urea, etc. The ruby will be eroded if it is exposed to too much sweat and not wiped clean immediately after wearing, which will damage the outer layer and affect its original brightness.
Hotan red jasper should avoid dust as much as possible. If there is dust on daily jadeware, it should be cleaned with a soft brush; If dirt or oil stains are attached to the jade surface, they should be brushed with mild soapy water and then washed with clean water. Do not use chemical degreaser. In addition, although the hardness of jade is high, it is easy to crack after collision. Sometimes, although the cracks cannot be seen with the naked eye, the molecular structure in the surface of jade has been damaged, with dark cracks, which greatly damages its perfection and economic value.
