2. Choose glass without bubbles and impurities in the glass body, and the objects passing through the glass will not deform basically.

3. Ceramic cups. The colored glaze on the ceramic cup contains heavy metals such as lead, which may have certain security risks. Therefore, it is best to choose colorless glaze, that is, white inner wall, which is the safest. Secondly, choose in-glaze color or under-glaze color, that is, the inner wall has colored glaze, but the surface feels smooth. The last time is glaze color, that is, the surface is uneven and will fall off with nails. It's best not to buy it.
