Health & Safety

Manufacturers Recommendations: Dinnerware Safe indicates the fired glaze surface meets the FDA standards for food safe, the fired surface is free of surface texture that could potentially trap bacterial, and the fired surface is chemically durable. Please note, dinnerware safety is not defined by cutlery scratches. Finished ware producers bear responsibility for dinnerware safe testing their ware being sold into commerce. 

We at Bath Potters will quote the manufacturers recommendations, but if you intend to make ceramic dinnerware with selling in mind, then you would be best advised to get your wares tested.

"I use a lot of underglazes and underglaze decals on my decorative pieces. This glaze was perfect, it doesn’t affect the details, smudge fine details and is perfectly smooth, crisp and bright. Two coats are ample, even if I water it down slightly. Always excellent service from Bath Potters, which always makes life much easier, especially when you have a looming deadline."
