When buying a ceramic bowl, first look at the appearance of the ceramic bowl, point the bowl at the light, and then carefully observe whether there are bubbles, black spots, impurities, bumps, transparency and so on on. If the ceramic bowl has these defects, you can't buy it. Such bowls are generally defective.
2. Listen to the sound
Tap the ceramic bowl with your hand. If the sound is crisp, it means that the quality of the bowl is better. If it makes a dull and muddy sound, it can't be bought. The bowl cracked when it was fired, so it made a dull and muddy sound.
Step 3 Touch the surface
Touch the surface of the ceramic bowl with your hands. If the surface is rough and uneven, don't buy it. Choose a ceramic bowl with a smooth and tidy surface.
4. Look at this color
When buying a ceramic bowl, you should also pay attention to the color of the ceramic bowl. Try to choose a plain ceramic bowl without patterns and colors, because bright colors will use a lot of pigments, which will increase the content of heavy metals and lead, which is easy to exceed the standard and is not good for your health. If there are patterns in the bowl, you should choose underglaze color or underglaze color.
5, flatness
Put the bowl on a flat surface to see if the bottom of the bowl is flat, then put the bowl upside down on the flat surface to see if the edge of the bowl is inclined. If it's not flat, you can't buy it.
6. Look at the bottom of the bowl
When buying a ceramic bowl, you should also pay attention to the height of the bottom of the bowl. If it is too low, it is easy to burn your hands. Try to choose a higher one, so it is safer to hold porridge and soup, and it is not easy to burn your hands.
7. Look at these patterns
Look at the pattern of the ceramic bowl, which is very important and related to whether the ceramic bowl is healthy or not. The patterns of ceramic bowls can be divided into glaze color, glaze color and glaze color.
It is best to choose bowls with patterns under ceramic glaze, which is what we usually call underglaze color. When firing an underglaze bowl, paint it first, then glaze it, and then fire it in a kiln at a high temperature of 800 degrees to 1400 degrees, so that the pigment on the pattern will be wrapped in glaze and will not penetrate out, so it is healthier to choose a bowl with underglaze patterns.
Glazed bowls are also healthier and can be bought. You must choose the bowl with underglaze color. The pattern is flat, the color is even, there is no obvious bright spot, and it is similar to being integrated with the bowl. When choosing a ceramic bowl, you should choose a brand of ceramic bowl, and the quality is more guaranteed.
You can't buy it if the pattern protrudes from the bowl surface. This kind of pattern is easy to fade and lead seep over time, which will lead to lead poisoning over time.
