This glaze series are lead-free and dinnerware safe. Most of them also come with the A/P non-toxic rating from the Art & Creative Materials Institute (ACMI) which is clearly marked on the product label. Some glazes are rated C/L by the ACMI which means that they are considered toxic in the liquid (unfired) state due to the presence of heavy metals, such as copper or vanadium, beyond the non-toxic legal limit. C/L rated glazes are not suitable for use by young children or pregnant women.

Recommended firing temperature is cone 5.
