As the saying goes: "The country is based on the people, the people take food as the heaven, and food takes safety as the first." For ancient people, the most important thing is survival. "Filling the stomach with a peaceful mind is the king's way, but with the gradual improvement of people's living standards, people initially consider enjoying food and clothing.". Tableware is very important for eating. Ceramic tableware not only has variable shapes, but also has variable appearances and images. It feels good and is easy to clean. It has become the first choice for many families to purchase tableware, so the question arises, how to choose?
1. Looking for regular merchants
When buying, be sure to choose a regular merchant, not from a hawker.. According to national regulations, ceramic tableware should be soaked in% acetic acid solution before leaving the factory. The dissolution amount of lead in tableware should be less than 7 mg/L, and the dissolution amount of cadmium should be less than 0.5 mg/L. Regular manufacturers can generally meet this requirement, but the seller is not sure.
2. Take a look
Check the color of the ceramic, whether the glaze is uniform, and whether the appearance and pattern are meticulous. It is best not to be rough - you can touch the surface or inner wall of the tableware again. High quality ceramics generally do not have uneven small particles.
3. Smell it
You can smell the smell of ceramic tableware. If there is a peculiar smell, it can only indicate that there are many harmful elements in the tableware. I suggest not buying it.
4. Choose one
Don't buy bright ceramic tableware just because you want to buy something beautiful and special. To a large extent, the brighter the color, the more heavy metal additives added to the glaze, the easier it is to exceed the standard and endanger human health. Choose some ceramic tableware using underglaze and underglaze color techniques. The production process is relatively strict and the content of heavy metals is not too high.
5. One for use
Before use, it can be boiled in boiling water for 5 minutes or soaked in vinegar for 2-3 minutes, which is more conducive to the dissolution of toxic elements.
