This is one of Spectrum's Stoneware Metallic glazes, which have beautiful metallic finishes. Mirror is runny and not good for applying on vertical surfaces.
Sample shown is on a white clay body.
Stoneware Metallic glazes are all lead-free, but not non-toxic due to the use of vanadium and/or copper. However, they are dinnerware safe if fired to the proper firing temperature.
