What's the difference between making tea in a teapot and making tea in other porcelain pots?

Teapots are used for making and pouring tea. It has long been concluded that the performance of teapot is "color, fragrance and taste". Moreover, scientific institutions have made detailed tests on sand teapots and ceramics, which proves that sand teapots are much superior to ceramics. This conclusion is based on the uniqueness of purple sand raw materials. The teapot is practical, because of its high porosity, which makes it have the advantage of good permeability. According to the History of Du Tao in China on page 394, purple clay is characterized by high iron content ... and there are a lot of aggregates in the microstructure of purple clay. There are two kinds of pores, one is the pore inside the aggregate, and the other is the pore group wrapped around the aggregate, most of which are open pores. The good permeability of purple clay may be related to this special microstructure. According to the determination of physical and chemical properties of various clays by Yixing Ceramic Company, it is found that the porosity of purple clay is as high as 10%. Therefore, it shows that good air permeability is of course the main reason for "rich color, fragrance and taste of tea" and "staying up late in summer". The good plasticity and bonding ability of purple sand mud are the reasons why it is beneficial to craft decoration. Moreover, the firing temperature range of purple sand is very wide, from 1 190℃ to 1270℃. At present, the firing temperature is controlled at about 1200℃, which is another reason why purple sand products are watertight and not aging, and the more they are used, the more shiny they become. All the above shows that this kind of purple sand soil mixed with fine sandy sandstone is the best clay for making pottery pots and a unique treasure in Yixing, Tao Dou. Now many people mistakenly think that all clay pots are teapots, but they are not. The purple sand pottery tea set made of purple sand pottery clay in Yixing, Jiangsu Province is recognized as the best tea set in the world. Identification and evaluation of teapot The connotation of a teapot must have three main factors: beautiful structure, exquisite craftsmanship and excellent use function. The so-called image structure refers to the spout, wrench, lid, buckle and foot of the pot, which should be coordinated with the overall proportion of the pot body. Exquisite skills are the criteria for judging the quality of pot art. Excellent practical functions refer to proper volume and weight, easy grip of pot body, smooth rut and seam of pot body, and smooth spout water. At the same time, we should consider the exquisite harmony of colors and patterns? If the aesthetics of teapot art is discussed abstractly, it can be summarized as four elements: form, spirit, qi and state. Form, that is, formal beauty, refers to the outline of the work, that is, the figurative face; God is verve, a charm that can make people experience spiritual beauty; Qi, that is, temperament, is the essential beauty embodied in pot art; State, that is, form, refers to various postures of a work, such as height, height, fat, thinness, rigidity, softness, squareness and roundness. From these aspects, it is a really perfect good work. But here we must distinguish between reason and interest. If the pot lovers are biased and haggle over the size of the pot, the pot mouth should be straight, the pot cover should be straight, the pot body should be tall and short, and the focus should be on making tea and drinking, then they will only be sensible and boring. Appreciation of art should be both reasonable and interesting. No matter how big or small the work is, whether the spout is curved or straight, whether the lid is vertical or flat, and whether the shape is high or short, it cares about interest, can generate emotions and nourish the soul, and can never tire of playing. Therefore, to appreciate a new style, we must first understand the essence of inverted beauty before we can comment on it. Starting from this aesthetic attitude, we can win the praise of sand fans. Of course, as a practical handicraft, its applicability is also very important, and the comfort in use can please the body and mind and cause harmonious interest. Therefore, according to the habits and customs of drinking tea, we should selectively consider the capacity of the pot body, the smooth outflow of water from the spout, the labor-saving comfort of holding the handle and so on. These must be considered within a specific scope? At present, the criteria for judging the quality of Yixing teapot can be summarized by five words: "mud, shape, workmanship, style and merit". The first four words are artistic standards, and the last one is functional standards, which are described as follows: 1. "Mud": the teapot is famous in the world and is inseparable from its production, but the fundamental reason is its superior raw material purple sand mud. When analyzing the raw materials of purple sand, many ceramic monographs in modern times talked about the composition of iron oxide in it. In fact, there are a lot of mud containing iron oxide all over the country, but purple sand can't be produced elsewhere, which shows that the key to the problem lies not in containing iron oxide, but in the "sand" of purple sand. According to the analysis of modern science, the molecular structure of purple sand mud is different from other mud, that is, the same purple sand mud, with different structures and subtle differences. In this way, due to the different raw materials, the functional utility and sensory experience are different. Good function and utility, high quality, otherwise poor quality; Good sensory perception leads to high quality, and vice versa. Therefore, to evaluate the quality of a teapot, the first thing is the quality of mud. The change of mud color only brings people different visual feelings, which is not helpful to function and feel. The teapot is a work of art with strong practical function. Especially due to the habit of use, the teapot needs to be explored constantly to make it feel comfortable and achieve the purpose of psychological pleasure. Therefore, the feeling of purple sand surface is more important than mud color. Compared with other clays, purple sand has a remarkable feature that it feels different. A person familiar with purple sand can tell purple sand from non-purple sand with his eyes closed. This is touching non-purple sand objects, just like glass objects-sticky hands, while touching purple sand objects is like touching bean paste-fine but not greasy, very comfortable. So it is very important to evaluate the feel of a teapot. The popular casserole in recent years is the product of emphasizing this quality and feel. The second is "shape": the shape of the teapot is the richest in all kinds of utensils in the world, and it is known as "the square is different and the circle is different". How to evaluate these shapes is also "different people have different opinions", because the social function of art is to meet people's psychological needs, since there are various psychological needs; Generous love, generous love, delicate love, Gu Zhuo's love for Gu Zhuo, playful love, everyone has their own love and can't be forced. From the author's point of view, I think Gu Zhuo is the best, followed by generosity, beauty and fun. What is the reason? Since the teapot is an integral part of the whole tea culture, the artistic conception it pursues should be "indifferent and peaceful, detached and refined" pursued by the tea ceremony. Gu Zhuo is in the most harmonious atmosphere, so Gu Zhuo is the best. Many pot makers know this truth and imitate Gu Zhuo. As a result, they lost their cuteness. You know, works of art are the expression of the author's mood, the result of self-cultivation, and irreplaceable by others. Therefore, there is no need to imitate. Many traditional shapes of teapots left over from history, such as stone peach, mine field, monk hat, mound ball, eggplant section, solitary mausoleum, plum blossom, antique, etc., are the only outstanding works left over from years of erosion and still shine in today's perspective. Now many artists are copying, and they all have similarities and differences. For example, according to incomplete statistics, there are more than 100 kinds of stone pottery pots, because artists at all times and all over the world have integrated their aesthetic interests into their works. Speaking of "form", people often compare it with the schools of teapot art, and think that the schools of teapot can be divided into "ribbed bag", "fancy goods" and "light goods". In fact, this is a very analytical method. The reason is very simple, just like the genre classification of a drama performer, it is not determined by what drama he plays, but by his pursuit of interest in drama performance. In their artistic career, once the art is mature, an artist will inevitably form his personal style, and several similar personal styles will become a genre. Art is feeling. The quality of teapot depends entirely on personal feelings. The "equal sample" and "equal potential" of a teapot are the "scales" of modeling. After talking about a lot of profound theories, it is likely that it will become more and more unclear. Isn't there a saying that you can only understand, but you can't explain? The artistic feeling depends entirely on the inner voice and the understanding of the heart, which is called "but I feel the harmonious heartbeat of the sacred unicorn". The third is "work": China's art has many similarities, such as the dance movements of Beijing opera and the freehand brushwork of Chinese painting, all of which belong to the bold category; Beijing opera singing and traditional Chinese painting meticulous brushwork are strictly listed; Modelling technique of Zisha Pot is similar to Beijing Opera singing and Chinese painting, and it is also very rigorous. Point, line and surface are the basic elements that constitute the modeling of teapot. In the process of teapot formation, it must be explained clearly. Just like meticulous painting, it is necessary to make clear the use of pens, twists and turns, and cadences. The face must be light and the hair must be hairy; The line must be straight and curved; Points must be square, round and round, and there can be no ambiguity. Otherwise, it is not a good pot. According to the special requirements of the molding process of teapot, the spout and handle should be absolutely in a straight line and the weight should be balanced; The spout should be closely combined with the lid. This is also the requirement of "work". The fourth is "money": money is money in the pot. Appreciating the teapot has two meanings: one is to identify the author of the teapot or the author of the poem. The other meaning is to appreciate the content of the inscription, the calligraphy and painting, and the seal (lithograph seal cutting). The decorative art of teapot is a part of China's traditional art, which has the remarkable characteristics of China's traditional art of "poetry, calligraphy, painting and seal". Therefore, in addition to mud color, modeling and production time, a teapot can also see literature, calligraphy, painting, epigraphy and many other aspects, which can bring more beautiful enjoyment to pot watchers. Traditionally, teapots are priced according to people, and famous pots are worth a hundred times. Especially in the commodity society. In this way, many famous imitations are easy to appear in the market, and counterfeit products are also very common, especially when buying famous pots. 5. "Work": The so-called "work" refers to the functional beauty of the pot. In recent years, new products of teapot emerge one after another, such as dazzling stars. Pot makers pay attention to the formal beauty of modeling, but often ignore the phenomenon of functional beauty, which can be seen everywhere. In particular, some pot makers don't drink tea themselves and know little about the habit of drinking tea, which directly affects the function of teapot, and some pots may even be "useless". In fact, the biggest difference between teapot and other works of art is that it is a very practical work of art, and its "art" lies in "use" and "quality". If the meaning of "use" is lost, "art" will cease to exist. Therefore, we must not ignore the functional beauty of the pot. Functional beauty of teapot
