为明朝宣德年间创制的焚香之炉，通常用于陵墓、寺庙及权势之家烧香，拜佛、祭祖神。

明朝300年间，制作了不可胜数的器物，可称上乘之作。宣德炉作为其中的一种，可谓前无所师法，后无能为继，不愧为天地间一精美绝伦的古董，是我国古代工匠智慧和艺术的结晶。

宣德炉的基本形制是敞口、方唇或圆唇，颈矮而细，扁鼓腹，三钝锥形实足或分裆空足，口沿上置桥形耳或了形耳或兽形耳，铭文年款多于炉外底，与宣德瓷器款近似。

宣德炉的特色：一是原料多，除铜之外，还有金、银等贵重材料加入，所以炉质特别细腻，呈暗紫色或黑褐色。二是炼次繁，一般炉料要经四炼，而宣德炉要经十二炼，因此炉质会更加纯细，如婴儿肤。流传历史

在位时，传说宫内的佛殿失火，金银、铜像都混成液体。又传说是佛典起火，金银珠宝与铜都烧结在一起，于是宣德皇帝命令将其铸成铜炉。宣德皇帝询问铸工说，铜炼几次才能精纯？铸工回答说用六火炼铜，就会现出珠宝的光彩。于是宣德皇帝命令炼十二火，把铜做成条。再用赤火熔化铜条，置于钢铁制成的筛格上，把先滴下的最精纯的选取出来制成炉，把仍存于筛格上的取出来制成其他的器物。

宣德炉在宣德中期模仿宋代的烧斑，掩盖了炉的本质，就用一种外国产的卤液浸润、擦拭、薰洗，把色彩变为蜡茶。到了宣德末期，则更加显示它自然色泽，着色更淡。后人评论说，宣德炉有五等色：栗壳、茄皮、棠梨、褐色，而以佛经纸的色泽

传世的宣德炉很少很少，且价格为天文数字，非常昂贵。

It is a incense burner created in Xuande period of Ming Dynasty. It is usually used in mausoleums, temples and powerful houses to burn incense, worship Buddha and worship ancestors.

During the 300 years of Ming Dynasty, countless artifacts were made, which can be called excellent works. Xuande stove, as one of them, can be said to have no way to learn from before, but can't be continued later. It is worthy of being an exquisite antique between heaven and earth. It is the crystallization of the wisdom and art of ancient Chinese craftsmen.

The basic shape of Xuande stove is open, square or round lips, short and thin neck, flat and bulging belly, three blunt cone-shaped solid feet or split crotch empty feet, with bridge shaped ears, Le shaped ears or animal shaped ears on the mouth. The inscriptions are more than the bottom of the stove, similar to Xuande porcelain.

The characteristics of Xuande stove are as follows: first, there are many raw materials, in addition to copper, there are gold, silver and other valuable materials, so the stove is very delicate, dark purple or dark brown. The second is that refining is more complicated. Generally, the furnace charge has to be refined four times, while Xuande furnace has to be refined twelve times, so the furnace quality will be more pure and fine, such as baby skin. Spreading history

When he was in power, it was said that the Buddha Hall in the palace was on fire, and gold, silver and bronze statues were mixed into liquid. It is also said that the Buddhist scriptures were on fire, and the gold, silver, jewelry and copper were sintered together, so emperor Xuande ordered them to be cast into a copper furnace. Emperor Xuande asked the foundry workers, how many times can copper be refined? The caster replied that if copper is smelted with six heats, the luster of jewelry will appear. So emperor Xuande ordered twelve fires to be smelted to make copper strips. Then melt the copper bar with red fire, place it on the sieve lattice made of steel, select the purest one dropped first and make it into a furnace, and take out the one still on the sieve lattice and make it into other utensils.

In the middle period of Xuande, Xuande stove imitated the burning spot of Song Dynasty, which covered the essence of the stove. It was soaked, wiped and smoked with a kind of foreign brine to change the color into wax tea. At the end of Xuande, it showed more natural color and lighter coloring. Later generations commented that Xuande stove has five colors: chestnut shell, eggplant skin, pear, brown, and the color of Buddhist Scripture paper

Xuande furnaces handed down from generation to generation are rare and expensive.
