High cost, not anti-scalding, the disadvantage of bone china cup is that its price is much higher than that of ordinary porcelain. Good bone china, such as bone china produced in Tangshan, can only be seen in high-end shopping malls. Why is the price of bone china higher than other porcelain? Because bone china has higher requirements on raw materials and processing technology than ordinary The porcelain is much taller.
The raw material of bone china is mainly processed by mixing calcium phosphate and clay in herbivore bone charcoal in a certain proportion, and the firing temperature of bone china is also very high, reaching above 1200°C, which greatly increases the cost of bone china , is also the main reason for the high price of bone china; another disadvantage of bone china is that because bone china is thin, it will be hot when it is filled with hot things. For example, when we serve soup, if we use bone china soup bowls, you You need to have certain skills to know where to hold it with your hands so that it will not be burned. That is, we press our thumbs on the edge of the bowl, and the four fingers extend from the bottom of the bowl. Because the bottom of the bowl is thicker, it will not be too hot. Hot, I will do a test, that is, if we have freshly cooked rice here.
The 25-inch Admiralty bowl for serving rice will not be hot by the way I mentioned above, and there is no problem at all. Of course, bone china is not satisfactory in these two points.
