普洱茶选建水陶:温度与湿度的均衡,恒温与呼吸的微循环插图

建水紫陶由纯天然的陶泥组成,里面主要的构成元素是以铁元素为主,附带含有微量的锌、硅和猛元素。

Jianshui purple pottery is made up of pure natural clay, and the main elements are iron, with trace zinc, silicon and ferocious elements.

泥的目数在250目左右,250目数大家可能有点陌生,我打一个贴切的例子吧,250目数的陶土即和我们女性朋友擦的脸霜细腻度相当。

The mesh number of clay is about 250 mesh, which may be a little strange to you. Let me give you a proper example. The clay with 250 mesh is equivalent to the facial cream our female friends wipe.

成型方式以拉坯成型为主,拉坯成型的特点除了成型快之外还有很重要的一点“柔”,这刚好破解了紫陶泥土的“刚”;为什么说紫陶的泥土是“刚”呢,因为紫陶泥的目数很细腻,所以泥土在除水的过程中互相的吸力是非常大的,以致泥土在拉坯前的状态是非常密实,泥门的透气性不高,所以说紫陶的泥土在制作好的时候是铁板一块的。

The molding method is mainly formed by casting. In addition to the rapid forming, there is also a very important “softness”, which just breaks the “rigidity” of purple pottery clay. Why is the purple pottery clay “rigid” because the mesh number of purple clay is very fine, so the mutual suction of the soil in the process of dewatering is very large, so that the state of the soil before casting is very high It is dense and the air permeability of the mud door is not high, so the clay of purple pottery is a piece of iron when it is made.

而拉坯的手法刚好破解了它的“刚”,在旋转坯体成型的过程中,坯体在不断的增高和变饱满,手势的不对称不断在拉伸这泥土的泥门,让原本密实的泥门在坯体的变化中变的松散起来。

In the process of forming the revolving green body, the green body is constantly increasing and becoming full, and the asymmetry of gesture is stretching the mud door of the soil, which makes the originally dense mud door loose in the change of the green body.

这刚好和宜兴紫砂的做法相反,紫砂因为泥土松散和目数比较低(通常60至80目之间)需要打片成型,即通过反复不断的敲打来增加泥土的密实度。建水陶是通过拉坯来降低泥土的密实度。

This is just the opposite of Yixing purple sand. Because the soil is loose and the mesh number is relatively low (usually between 60 and 80 mesh), it needs to be chipped and shaped, that is, the compactness of the soil is increased by repeatedly beating. Jianshui pottery is to reduce the density of soil by casting.

建水陶拉坯成型后的坯体掰开后可以目测到是呈现蜂窝状的。制好的坯体通过两周的自然阴干就可以进窑烧制了,经过高温烧制好的紫陶坯体结构依然呈现单气孔的蜂窝状。

It can be visually observed that the body of Jianshui pottery is honeycomb after it is formed. After two weeks of natural drying, the green body can be fired in the kiln. After high temperature firing, the body structure of purple pottery still presents a single pore honeycomb shape.

上面大家了解到紫陶的化学元素和烧成结构,下面就来说说紫陶和普洱茶的关联了,大家都知道普洱茶作为特殊的一个茶类,后期的储存和转化对普洱茶来说也是至关重要的,那么普洱茶需要一个什么样的储存和转化环境呢?

As we all know about the chemical elements and firing structure of purple pottery, let’s talk about the relationship between purple pottery and Pu’er tea. We all know that Pu’er tea, as a special kind of tea, is also very important for Pu’er tea. What kind of storage and transformation environment is needed for Pu’er tea?

我个人认为是温度和湿度的均衡,长期提供一个恒温和呼吸的环境是普洱茶储存和转化的关键所在。

In my opinion, the balance of temperature and humidity is the key to the storage and transformation of Pu’er tea.

当下市面上有各式各样的存储器皿,其中以景德镇的瓷器和宜兴的紫砂为主。

At present, there are various storage dishes on the market, including Jingdezhen porcelain and Yixing purple sand.

瓷器因为上釉的缘故表面呈现玻化状,因此在器皿内容易形成一个相对不受外界干扰的密封环境,这种环境有利于绿茶的存储,让绿茶的香气保持的更持久;却不利于普洱茶的存储,因为它不透气导致了普洱茶不能呼吸和转化。

Due to the glaze, the surface of porcelain is glassy, so it is easy to form a sealed environment which is relatively free from external interference. This environment is conducive to the storage of green tea, so that the aroma of green tea can be maintained longer; but it is not conducive to the storage of Pu’er tea, because it is impermeable, resulting in the inability of Pu’er tea to breathe and transform.

那么紫砂器皿呢?透气性好,密度低,有利于普洱茶的在转化。答案也是不对的,因为它缺乏提供一个长期恒温的环境,普洱茶的存储和转化并不是一朝一夕能完成的,而是需要长时间的存放才能有利于转化。

What about purple sand utensils? Good air permeability and low density are conducive to the transformation of Pu’er tea. The answer is also wrong, because it lacks a long-term constant temperature environment. The storage and conversion of Pu’er tea is not completed overnight, but needs a long storage time to facilitate the transformation.

紫砂因为目数低导致烧成后的坯体结构呈现双气孔环境,这种环境短时间不要紧,但长时间就不行了,器皿内的环境容易受到外围的气候干扰,过干燥或者过潮湿都不利于普洱茶的转化,干燥还好,一旦碰到梅雨季节空气湿度较大,普洱茶饼会变的软绵绵后会发霉,这点南方的茶友应该最有体会。所以紫砂器皿也不是最佳的存储器皿。

Due to the low mesh number of purple sand, the green body structure after firing presents a double porosity environment. This environment is not tight for a short time, but not for a long time. The environment in the utensils is easily disturbed by the surrounding climate. Too dry or too humid is not conducive to the transformation of Pu’er tea. Once the air humidity is high in plum rain season, Pu’er tea cake will become soft and moldy Tea friends in the South should have the most experience. So purple sand ware is not the best storage dish.

剩下紫陶了,刚刚说到紫陶烧制好后坯体呈现单气孔的蜂窝状,但是密度又比较大,这样制成的器皿后刚好提供了一个微循环的环境,即不像瓷器密不透风,又不像紫砂透气过大。

Purple pottery is left. As mentioned just now, the green body of purple pottery is honeycomb with single pores, but the density is relatively high. The vessels made of this kind just provide a microcirculation environment, which is neither airtight nor airtight like porcelain, nor too airtight like purple sand.

这样的微循环环境下,受到外界因素干扰小,在气候干燥的时候它里面能有相对湿度,在湿度大的季节因为它的单气孔又能提供一个相对干燥的环境,这两点刚好满足了普洱茶的存储环境,即能为普洱茶长期储存提供一个相对恒温和微循环的环境。

In such a microcirculation environment, there is little interference from external factors. When the climate is dry, it can have relative humidity. In the season of high humidity, because its single pore can provide a relatively dry environment, these two points just meet the storage environment of Pu’er tea, that is, it can provide a relatively constant temperature and microcirculation environment for long-term storage of Pu’er tea.
