Does anyone know if mica powder on a fused bottle is food safe? If not, does anyone know a glaze to put over it that would be food safe? I’m using it on a slumped wine bottle
The mica itself is pretty harmless (they use the same stuff for women’s make up) but the metal oxides they use to color it could be another story.
Thompsons Enamels makes a clear enamel for window glass that would probably work to cap the mica.
