The color glaze of most daily ceramic vessels is safe under normal use. However, some inexpensive or low-quality ceramic products may contain harmful substances such as heavy metals such as lead and cadmium. These harmful substances may seep into food or liquids, posing a potential threat to human health.
In general, the color glaze in ceramic products that have been properly fired and quality controlled is stable and will not release harmful substances. To ensure the safety of the ceramic utensils used, you can take the following preventive measures:
1. Purchase reliable brand ceramic products: Choose products from well-known brands or reputable manufacturers, who usually implement strict quality control.
2. Avoiding the use of damaged ceramic ware III: Damaged ceramic ware can cause the color axis to break or fall off, increasing the risk of harmful substance release.
3. Avoid using non-standard ceramic vessels: In some countries or regions, ceramic products may need to comply with specific standards and regulations to ensure their safety. Check and ensure that the purchased ceramic ware meets local standard requirements.
4. Avoid using ceramic vessels containing lead or cadmium: If you are unsure about the material and composition of the ceramic vessels used, especially for handmade art ceramics, it is best to avoid using them for food or liquid storage and consumption.
In summary, most quality controlled daily ceramic vessels are safe.
