Our glazes are not made with any toxic materials or lead. We stand by our clear glaze being food and smoke safe. Because we have not had our glazes tested and certified to be food safe, we recommend only using it as a decorative glaze for now.
If you want a glossy finish to your glow glaze, we recommend applying 1 clear coat. You can use a clear coat of glaze from a company that does have a certified food safe glaze to seal our glaze if necessary.
We want to keep you and others safe, so for now we think it would be best to use it as a fun decorative glaze where the glaze doesn't need to hold any food or similar consumables.
Please remember that a glaze will often contain silica as it is a glass former. Silica is very harmful to your lungs. If your glaze is dry it can lead to silica dust kicking up into the air, so be sure to wear a mask. And don't forget to read our terms and conditions so you know that you are responsible for keeping yourself safe when working with our ceramic materials.
