Mr. Li intends to continue the Tea Sutra, which will make the old qian's name immortal.
Tranquility and far-reaching, Fang De always, I am Lin Fangzhi.
Jianzhan is known as the "pearl of the porcelain altar".
In the cup, it contains stars, mountains and rivers, and also collects the universe and the rivers and seas, which is dazzling and seductive. Thousands of glaze colors highlight the elegant art of the Song Dynasty and represent a unique oriental aesthetic.
It also attracted the praise of Su Shifushi: "The bright window is poured with purple cups, and the color and taste are amazing." "In one lamp, you can glimpse the culture and splendor of the entire Song Dynasty, and as the craftsmen pass it on from generation to generation, they also convey the broad and far-reaching spirit of the Song Dynasty to the world."
I remember a tea friend once introduced Jianzhan to me like this: "If Jianzhan is in hand, it is not just tea when drinking tea." ”
I deeply believe that the beauty of Jianzhan is not only in the exquisite and chic shape of the shape, but also in the soup color and flavor that can set off the tea soup, but also in the ability to understand the light style and elegance of the Song Dynasty people by reading Jianzhan.
Tea lovers who love tea, understand tea, and understand life will never miss this two instruments. However, if you don't know these ten points of knowledge, don't say that you know Jianzhan.
1. What is Jianzhan?
Jianzhan, that is, the black glazed tea ware fired in the kiln, is one of the representatives of black porcelain, and is also one of the eight famous porcelains of the Chinese Song Dynasty, which was used by the royal royal tea ware during the Song Dynasty. Its glaze color is pure and varied, and it can form natural markings.
Jianzhan originated in Ouning County, Jianning Province, which is now called Jianyang, Fujian Province; and Jianzhan means a shallow and small cup, according to its shape, so it is called "Jiandian".
There are many titles for Jianzhan, such as "the only tea vessel born for tea", "the art of combining earth and fire with high difficulty", etc.
Second, the main characteristics of Jianzhan?
The glaze is built using positive firing, so the glaze along the rim is thinner, and the bottom of the cup will gather more glaze.
In order to prevent the glaze from staining on the base during the firing process, the outer wall is mostly half glazed, and under the action of high temperature, the glaze will automatically flow to form a hanging glaze, also known as "glaze tears" or "glaze drops".
Another feature of Jianzhan is the type of Jianzhan. Jianzhan is divided into four main types: bundle, skimmer, mouth, and open mouth. What they all have in common is that they all have large bowl mouths and small circles of feet, shaped like funnels.
Third, what are the glaze colors of jianzhan?
Jianzhan is commonly known as "into the kiln one color, out of the kiln thousands", the glaze color change of the jianzhan is not controlled by man, but by the temperature in the kiln and the atmosphere changes are determined, changing a variety of peculiar patterns.
We usually divide the glaze color of the cup into five types: black glaze, rabbit glaze, oil drop glaze, obsidian glaze and variegated glaze.
4. What is Dragon Kiln Wood Burning?
The dragon kiln originated in the Shang Dynasty, but it was not until the Song Dynasty that it was used as a kiln. At present, the known dragon kiln sites include Luhuaping, the back gate of the main road, the camp commander's tomb, the source pit, the cow pilun, and the Anwei Mountain.
Dragon kilns are generally built on the slope of the hill or inclination of mounds to form a long tunnel to form a kiln, which will form an inclined angle of 20-30 with the ground.
The dragon kiln has three parts: kiln head, kiln bed and kiln tail. The role of the kiln head is to preheat, the role of the kiln bed is to output the firepower, and the role of the kiln tail is to guide the fire upwards.
And firewood burning refers to the use of firewood fire kiln to make a cup, firewood burning is more uncertain, will be because of the difference in the part of firewood, resulting in different temperatures, resulting in the formation of various glaze colors, the real exquisite craftsmen, for firewood burning more fond of.
Fifth, what is the glaze and underglaze?
The so-called glaze and underglaze refer to the two states of jianzhan crystallization markings.
Supra-glaze crystallization refers to the glass layer under the glaze color, or the vitrified layer is relatively thin. Therefore, the iron crystal markings of jianzhan protrude from the glaze, and there will be a noticeable roughness to the touch;
The underglaze crystallization is the opposite, the vitreous layer is on top of the glaze color, completely covered with iron crystal markings, and the smooth and delicate cup surface can be felt by touch.
Interestingly, sometimes the same lamp may have markings in both forms.
6. What are the flaws of Jianzhan?
The firing process of Jianzhan can not be artificially interfered with, after entering the kiln, the development of Jianzhan is all by Providence, after firing at 1300 ° C, Jianzhan can form a delicate iron crystalline pattern.
Under the action of high temperature, the quality of the finished product is more uncontrollable, and it is inevitable that more or less defects will be formed, and common defects are: cracking, deformation, bulging, sticking kiln, uneven coloring, etc.
7. Is Jianzhan really poisonous?
Many people dare not use Jianzhan because they believe that Jianzhan contains heavy metals, which will lead to poisoning.
So does Jianzhan really contain excessive amounts of heavy metals? Let's first look at the composition of the glaze color.
The glaze color of the cup consists of three components. First, the glaze base, which is mainly quartz, has a high iron content, less clay, and belongs to the iron-calcium crystal glaze;
The second is the coloring agent, mainly minerals, for brown-red iron oxide;
The third is co-solvents, mainly grass and wood ash, feldspar and so on.
In terms of materials, Jianzhan is taken from nature, so heavy metal poisoning is not established. When choosing a jianzhan, as long as we confirm that it is an iron tire and is fired at 1300 ° C, it will not contain heavy metals.
8. How to cultivate the colorful treasure light?
After a period of use, a layer of natural colored light will be formed on the glaze, which is the "Seven Colored Treasure Light".
The colorful treasure light can be called a major feature of Jianzhan.
The formation of the seven-colored treasure light requires long-term maintenance of the jianzhan, which is what we often call "yangzhan". Raising cups is a natural and pleasant process that requires our care and patience.
Nine, the benefits of using Jianzhan to drink tea?
Using Jianzhan to drink tea, you can feel the culture and elegance of the Song Dynasty people through the millennium, which is the benefit of drinking tea with Jianzhan on the spiritual level.
In terms of practicality, the advantages of using Jianzhan tea include heat storage and insulation, softening water quality, etc.
Jianzhan has a special type, which is conducive to retaining the temperature of the tea soup and maintaining the flavor and taste of the tea soup; secondly, the jianzhan has the role of living water and soft water, which can make the tea soup more smooth and have the ultimate smooth and sweet.
Commonly used jianzhan tea drinking, can prevent anemia, hypertension, can regulate the human central nervous system, to achieve a soothing effect.
Jianzhan, born of tea, takes mud as a blank, takes the fetus as the body, takes the glaze as the clothing, and takes the rhyme as the soul. After reading "Jianzhan", I can understand the idle and elegant mood of the Song Dynasty people returning to the truth.
Life is scattered and impermanent, it is better to drink tea, slowly taste, and experience it carefully.
