Description

Technical Field

[0001] The invention relates to the technical field of artificial jade, and in particular to a method for manufacturing a light yellow raw material for arts and crafts. Background Art

[0002] Artificial jade is a material similar to natural jade that is artificially synthesized or processed and is widely used in jewelry, decoration, building materials, etc. Its appearance, texture and color are usually very similar to natural jade, but due to the artificial manufacturing process, the price is relatively low.

[0003] Artificial jade technology has existed in ancient times. Currently, artificial jade includes jadeite, chalcedony and agate. Natural jadeite is expensive, and artificial jade is usually made under high pressure and high temperature. When jade is prepared mainly with quartz sand, 10-50% lead oxide, 1-20% fluorite and 0.1-15% pigment are also added. The lead oxide evaporates and causes harm to the human body.
