Tea lovers who like drinking tea must know that tea sets are very important, because the quality of tea sets directly affects the quality of tea. Ceramic tea set is a very common tea set, so how much do you know about related tea sets?
First, white porcelain tea set
White porcelain tea sets are usually transparent or opaque high-temperature glazed tea ceremony utensils. In the long-term practice, the potters have further grasped the rule of porcelain discoloration, so on the basis of firing celadon, they reduced the content of iron oxide in the glaze and fired it with oxidation flame. The glaze color is generally yellow or blue with white in the middle, and the glaze color in reducing flame is blue, which is called celadon and shadow blue. In the Tang dynasty, the production of white porcelain was very developed and superb. Xing kiln in the north was first popularized. The white porcelain burned is as white as snow. It was once as famous as the southern Yue kiln for producing celadon, and is known as "white in the south and white in the north".
Second, porcelain tea sets
Porcelain tea set is a kind of porcelain with cyan high temperature glaze. The main coloring substance in celadon glaze is iron oxide, the content of which is about 2%. Glaze will show different shades and tones because of the different iron oxide content, glaze thickness and iron oxide reduction degree. If the iron oxide in the glaze is reduced to ferrous oxide, the glaze will be blue, otherwise it will be yellow, which is related to the firing atmosphere.
Sintering atmosphere refers to the flame properties when firing ceramics, which can be divided into three types: oxidation flame, reducing flame flame and neutral flame. Oxidation flame refers to the flame in which fuel is fully combusted to produce carbon dioxide; Reducing flame refers to the combustion of fuel in the process of hypoxia, which produces a large number of flames such as carbon monoxide, carbon dioxide and hydrogen carbide; Neutral flame is in between.
When fired with oxidation flame, the glaze color turns yellow, and when fired with reducing flame, it turns blue. Celadon is often decorated with open pieces. The so-called opening is due to the different expansion coefficients of tire and glaze, which leads to cracks in the glaze layer of porcelain. The surface of the Ge kiln handed down from ancient times is a combination of large and small pieces, small yellow and large black, so it is called gold wire.
The official kilns in the Southern Song Dynasty had better be cut, with thin tires (gray and black) and rich glaze layers (pink, yellow, blue and gray). ). The mouth edge of the utensil is slightly exposed due to the glaze depression, and the bottom foot of the utensil is exposed due to the cake pad, which is called purple mouth iron foot, which is expensive. Yue Kiln is famous for producing celadon. His works show a special color after rain, and the texture is like ice and jade. Later, it spread abroad and became the representative work of China porcelain.
Third, black porcelain tea sets.
Black porcelain tea set is black porcelain with high temperature glaze. The content of iron oxide in glaze is above 5%. Primitive black porcelain appeared in Shang and Zhou Dynasties, and the black porcelain fired in Shangyu kiln in the Eastern Han Dynasty had a uniform glaze surface with several glaze colors, such as black and dark brown, until a large number of black glaze varieties appeared in Song Dynasty. Among them, the rabbit hair pattern, oil drop pattern and obsidian tea bowls fired in the kiln are fired in reducing flame, because of the high iron content in the glaze, the heat preservation time in the kiln is long, and a large number of iron oxide crystals are precipitated in the glaze. The finished product presents colorful special patterns, and each one is unique and a rare and precious tea set.
Four, blue and white tea set
Blue and white tea set is one of the underglaze varieties, also known as "white glazed blue and white". Draw a pattern on the white body with a pigment containing cobalt oxide, apply transparent glaze on the outside, and then sinter at high temperature. When firing, the blue-white color is darker when using oxidation flame, and brighter when using reducing flame.
Five, painted porcelain tea set
Colored porcelain tea set is the general name of underglaze and overglaze colored porcelain. Under-glaze porcelain is made by decorating the blank with pigment, then coating it with cyan, yellow or colorless transparent glaze and firing it at high temperature. Overglaze porcelain is made by drawing patterns with various pigments on the fired porcelain and then baking at low temperature.
Six, enamel tea set
Enamel tea set is one of the over-glaze color varieties, also known as "porcelain embryo painting enamel", that is, painting with enamel on fired white porcelain. The main components of enamel are borate and silicate, mixed with different metal oxides. After low-humidity baking, it will appear in various colors, mostly with yellow, green, red, blue and purple as the background, and then painted with flowers and birds, mountains and rivers, bamboo stones and other patterns. The decoration has a prominent feeling.
Advantages of ceramic tea set
Good tea can only be brewed with good tea sets. We see that teapots, glass pots and iron pot are commonly used. Of course, the most common tea set is ceramic tea set. Why do many people like to make tea with ceramic tea sets? What are the advantages of making tea with ceramic tea sets that other tea sets don't have? Today, I will take the living porcelain tea set as an example to introduce this problem to tea lovers.
