| 由于含氧化铅的玻璃（俗称人造水晶）具有钻石般的高折光率及在高温下的高流动性，因此，铸造玻璃常选用人造水晶为材质。在中国市场上,一般将上述脱蜡铸造铅水晶玻璃制品称作琉璃。采用脱蜡铸造法可制作出造型复杂精美的工艺品。 Because the glass containing lead oxide (commonly known as artificial crystal) has diamond-like high refractive index and high fluidity at high temperature, artificial crystal is often used as material for casting glass. In the Chinese market, the dewaxing cast lead crystal glass products mentioned above are generally called glaze. The complex and exquisite crafts can be produced by dewaxing casting. 脱蜡精密铸造法：脱蜡铸造工艺是由古代铸造工艺发展而来的。距今5000多年前的新石器时代晚期，我国古代工匠就在青铜器的制造中广泛采用了失蜡铸造工艺。当时的工匠根据蜂蜡的可塑性和热挥发性的特点，首先将蜂蜡雕刻成需要形状的蜡模，再在蜡模外包裹黏土并预留一个小洞，晾干后焙烧，使蜡模气化挥发，同时黏土则成为陶瓷壳体，壳体内壁留下了蜡模的阴模。 Dewaxing Precision Casting Method: Dewaxing casting technology was developed from ancient casting technology. In the late Neolithic Age more than 5000 years ago, the lost wax casting technology was widely used in the manufacture of bronzes by ancient craftsmen in China. According to the plasticity and thermal volatility of beeswax, the craftsmen at that time carved the wax into the wax mold of the desired shape, then wrapped the clay around the wax mold and reserved a small hole. After drying, they roasted the wax mold to vaporize and volatilize. At the same time, the clay became a ceramic shell, leaving a negative wax mold on the inner wall of the shell. |
