How can cobalt become toxic in ceramic or porcelain?
Cobalt can become toxic in ceramic or porcelain when it is not properly bound to the material during the firing process.

This can lead to the ingestion of cobalt, which can be toxic to the body in high doses. To prevent this, it is important for manufacturers to ensure that cobalt is properly bound to the ceramic or porcelain during the production process.
