紫陶壶内部和外部的颜色为什么不一样?

原料相同的情况下,建水紫陶烧制后成品的颜色主要由烧制时窑内的氛围决定。

When the raw materials are the same, the color of the finished product is mainly determined by the atmosphere in the kiln.

建水紫陶的烧制方式并不神秘,稍微了解建水紫陶的朋友都知道:氧化烧制呈赭红色,强还原烧制呈黑色,弱还原烧制呈色介于赭红色和黑色之间,混合氛围烧制呈各种窑变色。

The firing method of Jianshui purple pottery is not mysterious. Friends who have a little knowledge of Jianshui purple pottery all know that: the oxidation firing is ochre red, the strong reduction firing is black, and the weak reduction firing is between ochre red and black, and the mixed atmosphere firing shows various kiln discoloration.

无论什么样的烧制气氛下,成品表面都会形成一层厚度约1毫米的火皮。最后打磨时,将火皮磨掉,才能见到紫陶的真胎。

No matter what kind of firing atmosphere, the surface of the finished product will form a layer of fire skin with a thickness of about 1 mm. Finally, when grinding, you can see the real body of purple pottery by grinding off the fire skin.

在强还原气氛下,紫陶成黑色,实际上表面的火皮颜色接近银灰色。打磨时,一般只打磨外部表面,壶内部不会打磨。一方面是平时不会刻意去看内部,另一方面是内部打磨很不好操作。

In a strong reducing atmosphere, the purple pottery is black, but the surface of the fire skin is close to silver gray. When grinding, generally only the external surface is polished, and the interior of the pot will not be polished. On the one hand, they don’t deliberately look at the interior; on the other hand, internal grinding is very difficult to operate.

火皮在内外都有,因此这位陶友提问说“紫陶壶内部和外部的黑色为什么不一样”,应该是他买了一把强还原气氛下烧成的紫陶壶,外部打磨出了纯黑色的紫陶真胎,而内部还是原始的火皮,因此有这一问。

The fire skin is both inside and outside, so the friend asked, “why is the black inside and outside of the purple pottery pot different?” it should be that he bought a purple pottery pot fired in a strong reducing atmosphere. The outer part was polished to produce a pure black real purple pottery body, and the inner part was still the original fire skin.
