Bone china manufacturers teach you to choose bone china tableware sets

Bone china manufacturers teach you to choose Porcelain Dinnerware Set sets. First look at the porcelain tableware. When buying bone china tableware, bone china and strengthened porcelain are better, both of which are the materials of top-quality tableware. Bone China is a recognized high-end porcelain in the world. It is natural milky white, has high permeability, and has a light and delicate texture. The molding and color formation of bone ash itself mainly rely on silica, alumina and calcium oxide. The higher the content of calcium oxide, the better the color. In nature, there are not many sources of calcium oxide, and animal bone meal is often chosen as the source of calcium oxide. Let's look at the way of flower noodle decoration. According to the characteristics of the flower surface, it can be divided into over-glaze, mid-glaze, under-glaze and colored glaze porcelain, and some white porcelain without color. The underglaze colors are mostly traditional blue and white and blue and white exquisite colors, the colors are relatively monotonous, and the price is moderate; the in-glaze colors are richer than the underglaze colors, and the product grades are higher, but the process requirements are strict, the cost is high, and the price is high; On-glaze bone china has rich colors, strong three-dimensional effect but low surface smoothness, and is easy to process, so the cost is correspondingly low. In addition to the different artistic effects of the above different decoration methods, the main difference lies in the content of heavy metal elements such as lead and cadmium. Among them, the lead and cadmium content of in-glaze, under-glaze, and most of the colored glaze porcelain and white porcelain are very low, and if the over-glaze color is used in the processing of bone china paper, inferior pigments, or on the flower surface In the design, if the amount of pigments with high lead and cadmium content is too large, or the temperature and ventilation conditions are not enough during baking, it is easy to cause the dissolution of lead and cadmium to exceed the standard. bought back should be soaked and boiled in vinegar water first, which can remove most of the toxic substances and greatly reduce the potential harm of Porcelain Dinnerware Set to the human body. Do not use Porcelain Dinnerware Set to store acidic foods and beverages such as juice, wine, coffee, etc. for a long time. This is because the longer the acidic food or beverage is stored in bone china tableware and the higher the temperature, the easier it is to dissolve lead, which is equal to aggravating the toxic and side effects of lead dissolution. It depends on whether the shape is correct, whether there are damage, spots, bubbles, and smooth. Bone china products with prickly, spotty, or even cracked surfaces tend to overflow the lead in the glaze, so they are not suitable for tableware. The glaze on the surface of porcelain white porcelin dinnerware is made by firing at a temperature above 800°C. If it does not reach 800°C, the low temperature glaze will be harmful to the human body. is best when it reaches 1350℃.
