JINGNIU? glass-ceramic has a thermal endurance far exceeding that of normal tempered glass. Tempered glass is generally limited to applications that do not exceed 500F. However, JINGNIU? is designed to operate at temperatures ranging from minus 400F. to plus 1000F. Glass-ceramic was invented in the 1960s. Its thermal endurance and stability make it ideal for many products: from stove tops and cookware, to missile nose cones and astronomical telescope mirror substrates. Transparent glass-ceramic, introduced in 1970s, is much more difficult and expensive to make than ordinary glass. As a result, it also has a different appearance including color, surface texture, and some small bubbles or inclusions that are natural to its composition and have no effect on its strength or performance.
