Ceramic tableware, to choose the right to health

Ceramic tableware modelling diversity, exquisite and smooth, the color is bright and beautiful and easy cleaning, is the vast majority of households to buy tableware of * * * *. But, unqualified ceramics, but could be a health killer. The unqualified product of pottery and porcelain, the glaze contains lead, mercury, radium, cadmium and other harmful to the body element, perennial use of dissolution, along with the food enters the human body, cause chronic poisoning. Should also pay attention to at the same time, the production of ceramic clay, inferior clay containing microbes and harmful material is more, if not on the colored glaze can damage human body health. Standard of colored glaze ceramic basic no harm to human body, while the threads look clean ceramic tableware for health. Therefore, ceramic product specifications and quality is particularly important to learn to choose. First of all, through the porcelain to choose ceramic tableware when the choose and buy, it is beautiful bone porcelain, strengthen porcelain, both are fine tableware materials. Bone China is the world recognized high-grade porcelain, it is a natural milk white, high transparency, texture and delicate. Bone China itself to shape and colour and lustre formation which rely on silicon oxide, aluminum oxide and calcium oxide, calcium oxide content of the higher, the color, the better. Overall, white jade, glittering and translucent moist, is all sorts of family ideal porcelain products. Secondly, from the point of flower surface decoration way on the flower surface features can be divided into the glaze color, glair, under the glaze color and glaze porcelain and some did not add white porcelain, etc. Under the glaze color is given priority to with the traditional blue and white and blue and white and exquisite, color is drab, moderate price; Glair colour than under the glaze color is rich, the product is higher, but the process is strict, and cost is high, the price is high; On colored glaze ceramic colour is abounded, stereo sense is strong, low surface smoothness, convenient processing, so the cost is relatively low. More than decoration in different ways, besides its artistic effect is different, the main difference is in the lead, cadmium and other heavy metal element content. Of glair, under the glaze color, and the vast majority of glaze porcelain, white porcelain of lead, cadmium content is very low, and at the time of the ceramic color paper processing glaze color if use inferior paint, or in the flower face design for high lead, cadmium pigments dosage is too large, or roast burning temperature, ventilated condition is not enough, it's easy to cause the dissolubility of lead, cadmium exceeds bid. Then, through the 'listen', 'than' and 'try' to choose to listen to: is listening to play gently knock at the sound of the porcelain. Such as, crisp sweet, explain porcelain body meticulous close-grained, no cracks, when high temperature firing, vitrified completely, the quality is better. Than: is to compare. To form a complete set of porcelain, want to compare various accessories, whether its modelling and decoration is coordinated. Especially the complete set of blue and white or blue and white porcelain exquisite, because the blue and white color on different sintering temperature are changing, so is with blue and white porcelain, color, dark and light is a few or even dozens of sets of cold porcelain, such as various pieces of blue and white color have obvious difference, the porcelain is far less. Test: test cover, fitting, is. Some porcelain with a lid, some porcelain composed of several components combined into, when choosing porcelain, don't forget to try to cover the lid, will try components assembly to see if appropriate. Finally, from the appearance to choose depends on whether appearance that week, to see if there is any breakage, spot, air bubble, smooth. Surface spiny, more spot, even with crack ceramics, the glaze contains lead easy to overflow, for tableware. To buy ceramic tableware, in addition, should be soaked with the vinegar water to boil, it can remove most toxic substances, greatly reduce the ceramic tableware potential harm to human body. Special note: do not use for a long time ceramic tableware for acidic foods and drinks such as fruit juice, wine, coffee. Because ceramic tableware cheng fang acidity food or drinks, the longer the higher the temperature, the easier it is to dissolve the lead, the side effects of dissolubility is equal to the increase of lead.
