Problems solved by technology

[0002] The texture of jade is delicate and tough, the color is warm and soft, and it has been loved by people since ancient times. However, the natural jade resources are limited and cannot meet the growing needs of people. Therefore, people use artificial synthesis technology to manufacture jade materials.
[0003] At present, there are a large number of artificial jade products on the market, which are widely used in the production of jewelry, handicrafts, and architectural decoration products, but most of these products use organic matter (unsaturated resin) as the main raw material and aluminum hydroxide as the filler. Manufactured, because the chemical composition and microstructure are relatively large from natural jade materials, the performance of these products is relatively poor, such as color, gloss, hardness, wear resistance, high temperature resistance, corrosion resistance, weather resistance, etc. Poor, susceptible to deterioration or damage due to various factors (mechanical, high temperature, corrosion, natural light) during use
Another type of artificial jade product currently on the market is made of waste glass as the main raw material, and some pigment raw materials are added at the same time for melting. However, the chemical composition of waste glass is relatively complicated, and the quality of the product is difficult to control and unstable.
[0004] Since 2009, the inventor of this patent has been using industrial solid waste and low-value minerals to develop artificial jade, but their melting temperature is higher than 800°C, and the high-temperature melting technology has some defects, mainly including: (1) High energy consumption and high production cost; (2) Great harm to production equipment such as furnaces and crucibles, requiring frequent maintenance and replacement; (3) Poor working conditions and great harm to operators; (4) Products Prone to deformation, cracking and other quality defects
