In the process of making teapot, mud is the most important factor and an important yardstick to determine the taste of teapot. There are many kinds of mud for making teapot, which are mainly divided into three categories: purple mud, red mud and green mud, and these three categories are divided into many small categories.
Among them, green mud can be divided into stage mud (raw ore stage mud, sesame stage mud and gold stage mud) and green mud (dark green mud and Benshan green).
Golden section: the structure of large granular loose body in mud is obviously double-hole structure, and the air convection is smooth; After a long time of use, it gradually showed its edge and developed the best equipment for raising pots with great changes.
The temperature of early mud mixing and early kiln entry is low, and the general satin mud products will "spit black"; The kiln used recently is a high-temperature kiln, and the satin pottery can be easily raised to the required temperature, truly achieving higher crystallization and never spitting black! Mining address: Huanglong Mountain, Dingshan, Yixing, Jiangsu? Sintering kiln temperature: about 1 150℃ shrinkage: about 13%.
Second, the cultivation method of teapot
I) step
1) Preheating: First, wash the inside and outside of the newly bought teapot with boiling water once to remove the dust on the surface, then put the teapot into a pot without oil stains and add boiling water three times the height for two hours, so that the muddy smell and internal heat of the teapot will be removed.
2) Reduce fire: put tofu in a teapot and boil it 1 hour. Gypsum contained in tofu has the function of reducing fire and can decompose the residual substances in the teapot.
3) Rebirth: Finally, choose your favorite tea and put it in the teapot 1 hour. Longjing tea is the best. In this way, the teapot is no longer a "dead thing". After rebirth, it absorbed the essence of tea, and the first time it was brewed, it could make tea people's teeth and cheeks fragrant.
2) Method
1) The function of wiping the surface of the teapot with a clean towel is actually to dirty the surface and polish it again. 2-3 hours a day. Don't leave tea soup on the surface of the teapot. Over time, the surface of the teapot will be covered with tea dirt and disfigured, which is a big taboo for players.
2) After a week, there will be red marks on the surface, which is gradually forming a patina bottom layer, and the color of the teapot will fade with time.
3) Let it stand for a week, let the teapot dry naturally, and at the same time, the surface contacts the air evenly to form a fine and uniform oxide protective layer.
4) Start the handwheel. At this time, the hands must have just been washed and dried. Please don't serve it directly to sweaty hands. It can be put on the disc in about 30 minutes every day. After a week or two, you can feel the teapot sticky. In fact, it has formed a thin patina.
5) After three months, you will see that the teapot is very aura. A well-wrapped teapot will show strong reflection, and some are like glass luster.
It is important to note that if the teapot is dirty, just wipe it with a slightly moist cotton cloth a few times, and then leave it for a while before playing. When you are in the dish, all areas of the teapot should try to avoid quick success and instant benefit, so you can only slowly move from one process to another, and you can also get a kind of spiritual pleasure with the change of the teapot.
Extended data:
Identification and selection of teapot
First, look, the texture of the real teapot is fresh and round, the visual effect is sub-smooth, and there are many evenly distributed small particles similar to metallic luster. The inner wall of some handmade pots has radial lines from the center to the periphery, which belongs to the processing process.
Second, touch, the real teapot feels delicate but not slippery, and the fake teapot feels rough or slippery; For example, ordinary clay feels rough, and porcelain feels slippery at first. If you press the friction slightly hard, you will feel astringent. This is due to the different manifestations of molecular structure.
Third, turn, turn the lid, the lid of the real teapot turns flexibly and smoothly, making a slight "filar silk" or "rustling" pleasant sound, while the fake teapot made of clay makes a dull "squeaking" sound.
Listen, knock on the jar with the lid. Although some people disapprove, it is very effective. The knocking sound of the real teapot is crisp and pleasant, and the sound is short, and the sound stops immediately after knocking; The fake teapot with ordinary clay has a dull, rich and short knocking sound; The sound of porcelain knocking is clearer than purple sand, a bit like the sound of metal impact, which is difficult for ordinary people to distinguish.
But a very obvious difference is that the wavelength of sound waves in porcelain is obvious. After the tapping, the sound still lasts for several milliseconds, and the real purple sand stops immediately.
Verb (abbreviation of verb) certificate: Generally, genuine teapot has a certificate written by the manufacturer. Certificates are usually written on rice paper, with a brush, and calligraphy is very beautiful. This is because calligraphy is a compulsory course for a good craftsman, and the value-added of a good teapot is more reflected in the skills of calligraphy and painting, which is stamped. The signature of the seal is the same as that on the bottom of the teapot.
Six, test the water, water poured on the real teapot, will not form obvious water droplets. Water is a relatively uniform piece, and then it will be gradually absorbed by purple sand.
