1. Laboratory Tested & Verified – Glazes that have undergone laboratory testing and demonstrate low metal release are considered safe for food contact.

2. Inherently Safe Materials – Glazes composed solely of materials that pose no known hazard are deemed food-safe, regardless of crazing.

3. Stable & Balanced Chemistry – Glazes containing potentially hazardous components are considered safe if they:

• Are properly fired within their intended temperature range
• Form a fully glassy, non-crystalline surface
• Meet recommended chemical stability standards for food-safe glazes

Important Note: Food safety depends on proper firing and application. When glazes are layered or fired outside their intended range, potters assume responsibility for assessing risks.
