Why the bone porcelain tableware so expensive? Every time they go to a master of China store, attracted by the beauty of the bone China, but to see the price, but also consider carefully, because the price of bone China are generally very expensive. Tangshan tangshan ceramics co. , LTD is a well-known bone porcelain factory, specializing in the production of high quality and low price of bone China tableware, tea sets and other products, is committed to let ordinary people can also be used on bone China! Bone China English name bonechina, is love China invented by the British. Is a kind of animal bone coal, clay, feldspar and quartz as the basic raw material, after high temperature, and low temperature burning burn fired twice to make porcelain glaze, is recognized in the world of porcelain. Its thin and transparent texture, has been widely welcomed. Chinese porcelain material is mainly kaolin, China stone, and a small amount of lime. And in the raw material of bone China there will be a 30 - 45% of the meal, so can have a good penetrability, can also do more thin, so looks glittering and translucent get rid of bone China, feel and look nice. Why is bone China porcelain in the royal family? Small make up are summarized, mainly from the following several aspects to talk about bone bone porcelain ceramic raw materials for animal bone coal, clay, feldspar and quartz as the basic raw material. Commonly used is the skeleton of cattle, sheep, pigs and other animals. British people think, 2 - 4, the mavs good bone as bone porcelain, sheep bone plasticity is good, easy to shape but whiteness than cattle bone, bone is a good raw material, sheep bone times, pig bone is poor. Bone porcelain craft has the good raw material, the more need good technology, or it will dissipate. When the bone content reaches the corresponding proportion, the quality of porcelain will greatly improve, this is mainly embodied in the vessels of gloss and moist degree. But if the content is more than the corresponding proportion, the composition of clay is relatively lower, porcelain will become too soft, the more easy to melt in the production process, need higher on the forming technology, is harder to fire, so more precious bone porcelain firing, after forming the bone China with 1250 ℃ high temperature burning, the association association due to bone porcelain shrinkage rate in the process of burning is very large, so the kiln after finished product will shrink by 20% ( General porcelain shrinkage 7%) , so easy to shape deformation, plate, bowl, etc on the requirements above quantico bowl to burn for a long time. Then the bending shape and size of the inspection, after the grinding surface to spray on glaze, kiln glaze to burn for 1150 ℃. Bone China color: general coloring method, was put on transfer paper is finished in white material, fired at 820 ℃ to osteogenesis bone China porcelain healthy environmental protection not only has beautiful appearance, and relatively ordinary porcelain also is helpful for people health. Porcelain items in daily use inevitably will be affected by acid and alkali corrosion and trace metals overflow, accumulate over a long period will affect human health. And bone China contains no lead, cadmium, glair, under the glaze color overflow, bone China not only lead, cadmium and flower surface wear, fall off not easily, except for the use of general tableware, also suitable for the microwave oven, green health ceramics is worthy. The colour and lustre of bone China including bone bone China due to China itself is a kind of natural milk white, with a popular words is with a little yellow, and this is characterized by any other porcelain cannot be copied. Now in the market mainly several big porcelain, such as white porcelain, shellfish porcelain, which is pure white, pearl that kind of pure white, we can be described as bluish white. Second, also is bone China, with a yellow degree can see the bone content of the bone China. For bone China, bone content is to distinguish the bone porcelain class is an important technical indicators, including bone bone China is better, the more the more the colour and lustre of bone China tend to be relaxing, on the contrary, if the low content of bone meal, yellow of the bone China itself is very obvious. Bone China permeability bone China is another important external characteristics appear a gender, but this feature is not bone porcelain proprietary. Now in the market of the shellfish porcelain, porcelain and pearl porcelain as long as do some thin, is also the existence of permeability. But the bone China and there is a difference between their permeability. Will different porcelain bowl pour on light bulbs, they fully reflect the effect is not the same. Bone content high master bone China as a whole is connected fully, low levels of both bone bone China with other porcelain on the transparent effect has obvious difference. Bone China bone China and an important external feature is the collision when the sound of the bone China. Will split two bone porcelain bowl on the collision on the hands, pay attention to the bone China is of high temperature firing porcelain, stiffness is very high, such a collision will not break. You can use a little force slightly collision, bone China collision is like a bell ringing from the dang ~; Voice and echo, echo for a long time. And other porcelain is the ding of the dark dumb, and basic no echo what has been discussed above, bone China is expensive. Generally good bone porcelain color uniform, partial milk yellow color, and good permeability, bone which is fully as a whole. Voice also has obvious characteristics of bone China collision sound is ringing, have echo. So consumers can differentiate the merits of the bone China from above.
