Hello all ~
I'm just beginning to learn how to use my new Paasche H sprayer &
compressor, and I'm using Duncan Velvet Underglazes, watered-down and
strained thru a 200-mesh. All of the underglazes I'm using say they're
lead-free and food-safe, but some of them also say, "Not for spray
application." (I just noticed the fine print). Why is this? Is it just
because they're too thick as they are (and of course wouldn't fit thru a
spray nozzle), or are they actually dangerous for me to use in spray? I
don't have a spray booth, but I do have a respirator that's rated for this
kind of thing, and I spray in a very well ventilated area with an overhead
exhaust fan going.
TIA

Yes they are led free and food safe if they say they
are.. The ones I have found that are not spray safe
are Reds and I think yellows.. So, they are food safe
after firing yet toxic before because of the lose
chem's... I wouldn't goof with spraying them evean
with all the precautions (booth, resparator, vents)

I don't think it is safe to say all glazes that are advertised as food safe
are. The conventional wisdom on this list seems to be - not until that are
tested or have no toxic ingredients in them.
I agree with that philosophy and think it is clearly in the economic
interest of potters be as sure as they can be - particularly in the face of
so much conflicting and erroneous information.
