Blue enamel is hazardous to health?

I glazed a water pipe clay with "Medditeranean Mist" and "Perriwinkle" is a mixture of dark blue. Could be dangerous to snuff the smoke out of it?

Everything depends on whether the enamel is toxic or not … enamel is toxic if is more dangerous when in liquid form and after being fired there will be food secure, but will be fine for other uses … you need to look at the bottle to see if the glaze is toxic or not to determine if it's OK to smoke
