Dewaxing precision casting method: The dewaxing casting process is developed from the ancient casting process. In the late Neolithic era more than 5000 years ago, ancient Chinese artisans widely used lost wax casting in the manufacture of bronzes. At that time, according to the characteristics of beeswax's plasticity and thermal volatility, the craftsman first carved the beeswax into a wax mold of the required shape, then wrapped the clay outside the wax mold and reserved a small hole. After drying, it was roasted to vaporize the wax mold At the same time, the clay becomes a ceramic shell, and the female mold of the wax mold is left on the inner wall of the shell.
Because lead oxide-containing glass (commonly known as artificial crystal) has a diamond-like high refractive index and high fluidity at high temperatures, cast glass is often made of artificial crystal. In the Chinese market, the above-mentioned dewaxed cast lead crystal glass products are generally called glazed. The dewaxing casting method can be used to make complex and exquisite crafts.
