一般来讲重量越重铜质就好。器壁的均匀和厚实是一个重要的原因~明清时期铜炉的鉴别方法：明代铜炉的整体风格是浑厚，到明末清初都是如此，发展到清中期风格开始趋向纤弱,在造型和装饰上浑厚不足。看包浆，真品包浆温润,宝气内蕴,长时间不变.伪品包浆枯槁,有的象油漆,越放久越难看。
In general, the heavier the weight of the copper, the heavier the weight. The uniform and thick wall is an important reason to the Ming and Qing Dynasties copper furnace identification method: the overall style of the Ming Dynasty copper furnace is vigorous, the late Ming and early Qing Dynasty are so, to the middle of Qing Dynasty style tend to be delicate in shape and decoration on lack of vigorous. See the patina, genuine patina moist, treasure gas inside, long time constant. Fake patina withered, some like paint, put more and more ugly.

其次是铸工，真品铸工质量平均,精品铸工相当精.伪品铸工不平均,有地方好有地方差,或者铸工粗糙。真品有自然均匀的磨损,特别是在足底.伪品无磨损或人为打磨。看铜炉表面的颜色，如铜炉表面氧化层颜色显黑色或黑色带绿,那是铜材料中含铅太高,不属纯铜；如铜炉表面生成绿锈,那是含锡太高,已接近青铜合金；如铜炉表面一擦就黄烂烂的,氧化层不致密,那是含锌太高,是黄铜合金.从表面质地上看,如被氧化的粗糙、不平,或者能见到砂眼等,那是黄铜合金铸造或是粗铜铸造。
The second is casting, casting quality genuine average, quite fine. Fine casting weipin casting does not mean, where good place, or rough casting. The genuine products have natural and uniform wear, especially in the foot. Look at the color of the surface of copper furnace, such as copper oxide furnace surface layer color black or black with green, it is the lead in the copper material is not too high, such as generating copper; copper furnace surface that is green rust, tin is too high, has been close to the bronze alloy; as a clean copper furnace on the surface of yellow rotten no, that is the dense oxide layer, zinc is too high, is a brass alloy. On the surface texture, such as rough, uneven oxidation, or to see the sand hole, cast brass or copper alloy casting rough
