Is the glaze of Longquan celadon teacup good for your health?

I am from Longquan. Let me answer this question. Longquan celadon is divided into brother kiln and brother kiln. Ge kiln is cut, generally used as an ornamental appliance, and there are many colors. The most distinctive colors of the kiln are pink and plum. If you choose Longquan porcelain tea set, it is recommended to choose the ground kiln. The black line at the entrance of Geyao kiln is painted with ink. The red opening line is painted red (on the decorative device). Of course, some tea sets in Geyao are original and can be purchased without ink treatment, but after all, the opening of Geyao is a kind of incomplete beauty, a structural installation of utensils, and not very reliable for daily necessities. Indeed, some utensils in Brother Kiln use unnatural pigment glaze, but Longquan Fuzheng is also very strict with celadon products. In addition, manufacturers generally have a sense of * * * to protect the reputation of celadon in their hometown. Longquan City Administration for Industry and Commerce has also repeatedly tested the daily-use porcelain whose lacquer color looks unnatural, and the results are qualified, which is harmless to human body. Why is this? Oh, the reason is that there is a misunderstanding in common sense that pigment glaze and chemical glaze are treated equally. In fact, all colored glazes of porcelain can be called pigment glazes, and all glazes added with minerals can also be called chemical glazes. Personally, it is more appropriate to call pigment glaze harmful to human body chemical glaze. Without pigment glaze or chemical minerals, porcelain can't be made at all. It should be pottery, ok! Longquan celadon is generally a glaze made of minerals that are harmless to the human body. The color of glaze changes with the change of iron content, most of them become black or yellow, and some become gray-green or white. Some celadon products are decorated with pigment glazes of other colors on the blank, and there is no glaze harmful to human body. It can be said that compared with other kiln systems, Longquan celadon has always used the least pigment glaze, and Longquan celadon pursues a color, a natural color. That kind of unnatural glass, yes, this kind of manufacturer didn't do it for long. Sorry, it closed down without a market. Even if it is used in ornamental appliances, it is vulgar. If you want to go to Longquan, you can see at a glance that you don't even want to aim at that vulgar and unnatural color. In fact, I can give you a more detailed introduction, but time does not allow, and my introduction description is not very good, but I want to say that you can basically buy and use Longquan porcelain tea sets with confidence.
