紫陶壶放明火上为什么容易烧裂?茶壶“流口水”怎么解决?

1、陶壶烧水为什么容易烧裂?

1. Why is it easy to crack when the pottery pot is boiling water?

答:实际上这个问题是在问陶壶为什么不能直接放在明火上烧,尤其是可以快速将水烧开的高温明火。

A: in fact, the question is why the pottery pot can’t be directly burned on an open fire, especially a high-temperature open fire that can quickly boil water.

根本原因在于陶壶属于脆性材料,而且性质上热胀冷缩。超过1100℃的高温烧制,使得陶坯烧结度非常高,可供缩胀的空间已经非常小。一旦局部接触明火,温度迅速升高,体积变大,所产生的张力就会破坏陶坯,导致烧裂。

The basic reason is that the pottery pot is a brittle material, and it expands and shrinks in nature. The sintering degree of ceramic body is very high when the sintering temperature is over 1100 ℃, and the space for shrinkage and expansion is very small. Once the local contact with open fire, the temperature rises rapidly, and the volume becomes larger. The tension generated will destroy the ceramic body and lead to cracking.

只有在原料中添加相关材料,使得烧制后的陶坯韧性增大或者耐高温性能增强,陶壶才有可能直接放在明火上烧开水。

Only by adding relevant materials to the raw materials can the toughness and high temperature resistance of the ceramic body be enhanced, can the pot be directly put on the open fire to boil water.

2、茶壶“流口水”怎么解决?

2. How to solve the problem of “drooling” in teapots?

答:倒茶后收壶时茶水沿着壶嘴往下流,这种现象被一些壶友称为“流口水”。

A: when the teapot is collected after pouring tea, the water flows down the spout. This phenomenon is called “drooling” by some pot friends.

一把壶是否会流口水,与壶嘴造型有很大关系,壶嘴造型则是由壶型来决定的。最常流口水的就是直嘴,比如西施、龙蛋、石瓢,都是采用直嘴,所以这几款壶,几乎都是会“流口水”的。

Whether a pot will drool or not is closely related to the shape of the spout, which is determined by the shape of the spout. Straight mouth is the most common drool, such as Xishi, Longdan and Shipiao. They all use straight mouth, so almost all of these pots will “drool”.

其实,“流口水”根本不成其为一个“问题”,也就无所谓“解决”了。因为某一些壶型采用的壶嘴,造型上就决定了不会流口水;但是另一些壶型的壶嘴,“流口水”则是一种正常现象。

In fact, “drooling” is not a “problem” at all, and there is no such thing as “solving”. Because the spout of some pot type is determined not to drool in terms of shape, but in other types of spout, “drooling” is a normal phenomenon.

3、建水紫陶能手捏成型吗?

3. Is Jianshui purple pottery good at hand shaping?

答:建水紫陶泥料目数高,很细腻,黏性强,可塑性不高,但是仍然可以做到手捏成型。

A: Jianshui purple clay has high mesh number, fine texture, strong viscosity and low plasticity, but it can still be kneaded by hand.

其实,市面上早就已经有了一些手捏的茶杯;而一些制壶工作室也制作出了很富有个性的手捏茶壶。

In fact, there are already some hand-held teacups on the market, and some pot making studios have also produced very personalized hand-held teapots.
