1. Some fake teapots are made of mud and then colored. At present, there are few raw materials, and industrial raw materials are mixed, which is harmful to human body. Because it is not pure ore, it needs to be reinforced with something.
2. Some manufacturers make fake teapots by adding chemical raw materials or ceramic pigments to color the clay and processing it.
3. Some manufacturers will add glass water in order to increase brightness. In order to turn it into an antique color, they put shoe polish on the pot, so there is a danger of poisoning when making tea.
4. The heavy metals in these artificial "Zisha" tea sets have a high melting point, so it is difficult to volatilize during the calcination of Zisha pottery. It will eventually remain in the fired tea set, which may be dissolved in different degrees when used, which will have an impact on the body.
Due to the above four or more reasons, a large number of heavy metals have been added to the fake teapot. If human beings ingest metal ions such as barium, manganese, cobalt and chromium for a long time, it will endanger human health.
Mild people have dizziness, headache and other performance hazards; In severe cases, there will be symptoms of multiple systems in the whole body.

Raw materials for making a real teapot:
The raw material for making purple sand pottery is a kind of hydrated aluminosilicate mineral clay, which is produced by long-term weathering and geological action of feldspar-bearing rocks in the earth's crust. It is widely distributed in nature and has a wide variety, and most areas in China are rich in reserves. Its main components are silicon dioxide, aluminum oxide, iron oxide, manganese dioxide, calcium oxide, magnesium oxide, potassium oxide, sodium oxide, titanium oxide and crystal water.
Therefore, the raw materials for making purple sand pottery are widespread in various regions (some fields are also good raw materials for making purple sand, but they must be approved by the land department). There is no truth. According to the different purple sand pottery products, you can also add some of the above oxides, which is the professional formula. There is no such thing as "chemical material" because it needs to be fired at high temperature (generally above 1 100).
