宣德炉作为一类器物的统称,似乎很难涵盖所有器形,应以明清古籍和档案中常见的宣铜代替之。而宣铜显然又不是固有概念中古代的青铜、红铜。那么这到底是一种什么材质?它的出现和使用情况又有着怎样的流变呢?选取流传有绪的宣铜器进行无损检测是一种行之有效的方法,其结论为黄铜无疑也是科学的。其中,含锌与否是鉴别黄铜的标准,而锌含量的多少又是区别古代黄铜与现代黄铜的依据。 Xuande furnace as a class of utensils collectively, it seems difficult to cover all shapes, should be the Ming and Qing dynasties and archives commonly used in the replacement of declared copper. Declare copper is obviously not the ancient concept of ancient bronze, red copper. So what exactly is this kind of material? What kind of rheology does it appear and how it is used? Selecting non-destructive testing of the well-proclaimed Xuan Tong is an effective method. The conclusion is that brass is undoubtedly scientific. Among them, the zinc is the identification of brass or not, and the amount of zinc is the difference between ancient brass and modern brass basis.
