据历史记载，宣德三年，皇帝下旨铸铜炉，合计一万八千余件，现竟然失落得几乎无迹可寻，就连台湾的故宫博物院，也仅收藏了四座。其实，当时宣炉除了供御用外，也用来分赐给诸王、臣下及京内各郊祭坛，甚至于各地的闻名寺院，分布得非常广泛，然而在改朝换代之际，许多宣炉（包括后仿炉和私款炉），不但失散了，甚至于销毁，至今宣炉已成为可遇不可求的珍品，后仿炉、私款炉亦珍贵。原因是宣炉在短短的四五百年间遭到了多种劫难。

According to historical records, in Xuande's three years, the emperor ordered more than 18,000 copper stoves to be cast. Now there are almost no traces of lost stoves. Even Taiwan's Palace Museum has only fourkeliji.89ix.compeidianx.89ix.compeidiany.89ix.compeidiang.89ix.comkaiguanguig.89ix.comjiliangx.89ix

.com stoves. In fact, at that time, besides being used for Royal purposes, Xuanfu was also used to distribute to kings, ministers and altars in the suburbs of Beijing, even to famous monasteries all over the country. However, during the period of Dynasty change, many Xuanfu (including the latter imitation furnace and the private money stove) were not only lost, but even destroyed. So far, Xuanfu has become an inexpensive treasure, and the latter imitation stove stove and private money stove are also precious. 。 The reason is that Xuanlu suffered many kinds of calamities in a short period of four or five hundred years.
