I would like to use two commonly posted ^5 glazes for food, but don't
remember anyone saying if they-ve been tested to be safe.

One glaze is Val's turquoise
The other was posted with many names....pink w/ purple streaks,
raspberry, pink opal....etc.

Anyone know if these are okay for dishes?

Hi!
with such a low % of chrome, I think it is foodsafe.
