What are the characteristics of purple sand tea?

1) Use a purple clay pot to make tea, the tea aroma is rich and long-lasting. The purple clay spout is small and the lid is tight, and the inner wall of the pot is rough, which can effectively prevent the aroma from being lost prematurely. The long-term use of the purple sand teapot, the inner wall is hung with a layer of brown-red tea scale, the longer the use time, the more tea scale accumulates on the inner wall, so the tea soup is more mellow and fragrant after brewing tea.

The long-term use of the purple sand teapot, even if you don't put tea and only pour boiling water, still has an attractive tea aroma, which is not possible with general tea sets.

2) The purple sand teapot is not glazed inside and outside, maintaining tiny pores, good air permeability, but impermeable, and has a strong adsorption force, which is incomparable to the general teapot. It can keep the aromatic oil in the tea to volatilize when heated and form a fragrant fragrance, improve the late acidity of the tea soup, and play a role in astringency and sterilization. Therefore, it can slightly delay the mildew of tea and become rancid, the so-called "summer is not rancid", the truth is here.

3) The purple clay pot makes tea, and the heat preservation time is long. Because there are many small bubbles inside the wall of the pot, and the bubbles are filled with non-flowing air, the air is a poor conductor of heat, so the purple clay pot has good thermal insulation performance.

4) Use a purple clay pot to make tea, and it is not easy to hold it. The linear expansion coefficient of the purple clay pot is slightly higher than that of the porcelain pot, and there is no glaze, so there is no problem of billet glaze stress; After firing, the purple clay pot has very little glass, which is enough to overcome the rapid change caused by the temperature difference between cold and heat, so it has slow heat transfer. The purple sand teapot has an excellent ability to adapt to the rapid change of heat and cold, and even after steaming in the upper high temperature, it will not burst if it is quickly thrown into the ice and snow below zero.

Therefore, making tea with a purple clay pot is not easy to carry; In the cold winter, make tea with boiling water, and you don't have to worry about cracking, even if you put it on a simmer, there is no risk of bursting.

Purple sand tea set is a kind of pottery tea set. It is dense and hard, with natural mud color, mostly purple sand, but also red sand and white sand. The fire degree of the pottery is 1100-1200 degrees Celsius, no water absorption, and the sound is thick and long.

It is cold and heat resistant, make tea without cooked soup taste, can be true and fragrant, and the heat transfer is slow, not easy to burn, use it to stew tea, will not burst.

Therefore, in history, there was a saying that "a pot weighs not counting two, and the price weighs every twenty gold, which can make the soil compete with the **". However, the fly in the ointment is limited by the color, and it is difficult to appreciate the beauty and soup color of the tea with it.

Today, the purple sand tea set is fired from a special clay buried in the south of Yixing, Jiangsu Province and the adjacent north of Changxing, Zhejiang, that is, Zijin mud. This kind of clay has a large iron content and good plasticity, and the firing temperature is about 1150 degrees Celsius.

The color of the purple sand tea set can use the difference between the purple mud and the texture, after "clearing" and "washing", so that it can appear in different colors, such as making the azure mud dark liver color, honey mud is light ochre color, stone yellow mud is cinnabar color, pear skin mud is frozen pear color, etc.

In addition, it can also be blended with purple mud of different textures to make it appear bronze, light ink and other colors. High-quality raw materials and natural color have laid a material foundation for firing excellent purple sand tea sets.

The purple clay pot has been used for a long time, and the "tea rust" accumulated on the wall of the pot, so that the empty pot is injected with boiling water, and the tea fragrance will overflow, which has a certain relationship with the pores of the purple sand pot fetal material, which is the unique quality of the purple clay pot, and other porcelain is not.

4. The purple clay pot has a very good conversion performance of hot and cold rapid change, and in the cold winter wax moon, boiling water is injected into the pot, and it will definitely not swell and crack due to sudden temperature changes. At the same time, the sand heat transfer is slow, and it will not be hot to hold after making tea. The most amazing thing is that it can also be cooked on a simmer to heat up, and it will not burst due to fire.

5. The longer the purple sand is used, the more bright and bright the color of the pot body becomes, and the charm is gentle. The purple clay pot will be used for a long time, and the body will become more shiny and lovely due to stroking and wiping, and the value will be higher and higher.

The raw material of the purple sand pot is the purple sand mud, the purple sand mud has a good plasticity, taking the purple clay as an example, its liquid limit is, the plastic limit, the index is, it is highly plastic, and can be arbitrarily processed into different shapes of the gods and goddesses. Strong adhesion when making, but it does not stick to the tool and does not stick to the hands.

For example, the mouth and the handle can be made separately, and then glued to the body of the pot can be carved with mud and processed for processing. The clay chips of square utensils can be bonded with grease sludge (more water can be added) and then processed. Such a large process capacity allows potters to fully express their creative intentions, display their craft skills, and further improve their skills.

2. The drying shrinkage rate is small. The drying shrinkage rate of the purple sand pot is small, the shrinkage of the purple sand pottery from the clay to the firing is about 8%, the firing temperature range is wide, the deformation rate is small, and the green strength is large, so the mouth cover of the teapot can be tightly fitted, and the shape contour line is strict and not distorted. The handle can be thicker than the porcelain pot, not afraid of the spout surface of the pot out of roundness, so that it fits with the proportion of the mouth, and can also be made into an open vessel and a large-mouth teapot with the same size as the mouth and the body of the pot.
