|Xin xiang Ceramic Mug Manufacturer, Ceramic mugs are a kind of daily drinking utensils. Because ceramic mugs have their own characteristics: health, environmental protection, heat preservation, and personality, ceramic mugs are generally used for hot drinks such as milk, coffee, and tea. The mug body is generally standard cylindrical or quasi-cylindrical and has a handle on one side of the mug body. The shape of the handle is usually a half ring. Our common ceramic mugs are divided according to their raw materials and firing process: ceramic mugs, white porcelain mugs, bone china mugs and stoneware mugs. Xinxiang Ceramic Mug Factory will systematically introduce ceramic mugs today.
1. The "core" of the ceramic mug - porcelain clay:
The raw material of the ceramic mug is china clay. The composition of China clay is mainly kaolin, and contains feldspar, quartz stone and mullite components. Porcelain mugs kneaded from china clay - biscuits, are fired in a kiln. The ceramic mug carcass of Xinxiang Ceramics Factory needs to be fired at a high temperature of 800°C to 1300°C to have the physical properties of porcelain. Because the porcelain clay is different, the firing temperature is also different, and the sintering shall prevail. The ceramic mug fired in this way looks ugly. The color is off-white, the surface is not smooth, and the water absorption and air permeability are high. Such a mug cannot be used directly. We need to cover the outer layer of the mug with a layer of film—glaze.
2. The "clothes" of ceramic mugs - glaze:
The ceramics we use every day are generally covered with smooth and smooth clothes, especially daily-use ceramics, which are more particular about "clothes". Some are as white as jade, and some are colorful and very beautiful. This kind of clothes of ceramics is called "glaze"
Glaze is a continuous vitreous layer attached to the surface of a ceramic body, or a mixed layer of vitreous body and crystal. The glaze may be produced by the calcium-containing stones and charcoal ash used in the ancient Leishi cooking, or it may be inspired by the beautiful texture of the shell surface, and it is consciously made of shell powder as a raw material. Xinxiang Ceramics Factory learned that as early as the Shang Dynasty in China more than 3,000 years ago, our ancestors had learned to use rocks and mud to make glazes to decorate ceramics. In the Han Dynasty, paper-warm lead glaze using lead as a flux was invented. Later, ceramic artists took advantage of the phenomenon that kiln ash naturally fell on the body and could be combined into glaze, and then used plant ash as a raw material for glaze making. The glazes used in the production of modern ceramic mugs are divided into lime glaze and long ancient glaze. Lime glaze is made of glaze fruit (a natural mineral material similar to porcelain stone) and gray glaze (mainly composed of calcium oxide). Feldspar glaze is mainly composed of quartz, feldspar, marble, kaolin, etc. Adding metal oxides to lime glaze and long ancient glaze, or infiltrating other chemical components, will become a variety of glaze colors.
Generally, the thickness of the glaze is only 1%-3% of the thickness of the body, but after being fired in the kiln, it is tightly attached to the porcelain body, making the porcelain dense, soft, and impervious to water and air, giving people a bright mirror-like appearance. Feel. At the same time, it can improve the use intensity, prevent pollution, and facilitate cleaning.
There are many types of glazes. According to the body, there are porcelain glazes, pottery glazes and flint glazes; according to the firing temperature, glazes fired below 1100°C are called low-temperature glazes, and glazes fired between 1100°C and 1250°C are called low-temperature glazes. The finished glaze is a medium-temperature glaze, and the glaze fired above 1250°C is a high-temperature glaze; according to the characteristics of the glaze surface, the white glaze is probably because people love silverware, and the colored glaze is welcomed by people because of its colorfulness. The patterns of the glaze change beautifully, the kiln pattern glaze is dazzling and beautiful, and the cracked glaze is clear, simple, elegant and unique. In addition to the above, there are matte glaze, opacified glaze, salt glaze and so on.
The above ceramic raw materials and production knowledge are too professional for us, and have no practical application significance. We usually buy ceramic mugs by ourselves or accept promotional mug gifts from companies. So how do we choose ceramic mugs?
1. Look at:
It is mainly to observe the color and texture of the ceramic cup with eyes. Ceramic cups are divided into manual and mechanical glazing. According to the technology, it is divided into: dipping glaze and spraying. Most ceramic cups are glazed by hand and supported by a tray, so there is always a circle at the bottom of the coffee cup that is not glazed. The bottom of the unglazed ceramic cup is rough, and its width and position vary according to the processing technology. Some of the rough surfaces are at the bottom of the ceramic cup, and some are on the inner side of the bottom of the ceramic cup. When choosing a corporate promotional gift cup, we should choose a cup with bright color and uniform color.
Touch the ceramic mug with your hands, choose a smooth ceramic mug, especially the mug mouth and outer wall, and also pay attention to the inner wall of the mug. Touch whether the handle is smooth and whether the bottom of the mug has been polished.
Weigh the weight of the pottery ceramic cup with your hand. In the case of the same size, the heavier ceramic cup has a thicker body, better heat resistance, and is stronger and more resistant to falling. On the contrary, under the same size, the bone china cup is thinner, has better heat dissipation performance and is lighter.
4. Listen to:
Flick the edge of the ceramic mug with your fingers and listen to the sound. If the sound of the ceramic mug is thick and stuffy, the mug is made of more materials and has good heat resistance; if the sound of the ceramic mug is crisp and loud, it has strong thermal conductivity.
Ceramic mugs are made from mud and rocks by fire. Ceramic coffee mugs will not waste our living resources, nor will they pollute the environment, nor will they destroy resources, and they are non-toxic and harmless. Xinxiang Ceramics Factory believes that the selection of ceramic mugs reflects the awareness of environmental protection and the care of our living environment. Most ceramic mugs are different due to custom picture or color. If the enterprise needs to design or customize ceramic mugs, please contact Xinxiang Ceramic Mug Manufacturer.
