Dear clayartists:
I am toying with the idea of spraying small amounts of glaze on pottery
to hopefully create interesting effects...texture, variegation of color,
runs, etc. I have read about paint sprayers, airbrushes, etc. but would
like to try something very basic, namely a mouth sprayer. I saw one
demonstrated in a video that looked like an atomizer but the "details"
were not discussed. I have also read of their use in books and CM
articles. I would appreciate any advice on this subject. Type of
glazes, oxides, stains to use and not use? Consistency of liquid to
spray? Precautions? Where to obtain? Can I make one? Specifically,
does anyone have experience with the simple-looking device advertized in
CM by Trinity Ceramics Supply in Dallas, Tx (CM May 99, p74) which
presumably works on the Venturi principle?
Thanks for the help. Dave, in Olympia.... where summer has come and
gone.

I have one of these little things, got it after a seeing Richard Zakin
use one at a work shop, he said that it would work better for me after a
bit of practice. I think that people who play brass instruments will do
well with these. you really do have to blow hard, long, and with a lot
of consistency to get a good even coat. oh yes, it helps if you are
co-ordinated too. because you have to hold the bottle, the sprayer, and
move your head and hands in the pattern that you want it to cover. So
if you are doing little spritzes, or small areas they are okay, every
so often I will get it out and mask areas of platters, spray underglaze
and then remask and spray several times, I get neat impressionistic
designs.
got mine at an art supply store, they are called fixitive sprayers
there and the thinnner the better for whatever you want to spray.
But I just picked up a nice compressor at a yard sale, and will be
getting an air brush of some sort to spray washes of oxides, and glazes
over each other to get some depth for the electric firing that I do.

Bath Potters Supplies sell a great mouth sprayer which is ideal for spraying
small areas, both Steve Mills and Mike Bailey are on Clayart and I'm sure
they could explain how the thing works. It is easy to use and easy to clean.
I've only used mine for glazes so far.

Dave...I've got the Trinity Atomizer you're referring to and it works fine
for a quick large area spray. The glaze(?) must be thinned to a very liquid
state. I use it to spray soda ash in a water base (100 ml H2O:20 gm Soda Ash)
I've used it for thicker glazes and nearly blown my brains out. If you odn't
watch it you and get very dizzy.
My best advice... Don't inhale.
The fact that I can work fast and without a lot of cleanup are the two most
important parts of using the atomizer.
Best of Luck

Hi, Dave,
I've used a mouth atomizer for years to spray stain and oxide over
glazes. The stuff you spray has to be pretty watery, though, or you'll
herniate yourself trying to get it to go through the sprayer. So you
can't really spray glazes very effectively with one. I've seen them
advertized in ceramics supply catalogues, but you should be able to get
one at any art supply store. Ask for a mouth atomizer. It's what
painters used to spray varnish on their paintings before aerosol was
invented.

Dear Dave,
In the Jurassic Era I used to use those sprayers to
apply fixative to my charcoal drawings. One of
my potter friends uses it to apply stain washes over
leaf shapes on her platters. Now do not expect to achieve
a real fine air brush effect as you will not get it. You will
get an uneven spray similar to rubbing a toothbrush on a piece
of screening. My friend's platters are beautiful but the effect
makes it obvious that they are not airbrushed.
I was unable to find them at craft shops but I did find them at an
art supply store.
In terms of safety I guess it depends on what you are using
perhaps someone else can address that area.
I hope this helps.

David,
I use one once in a while. They can be bought at most art supply stores.
The glaze has to be pretty thin almost like water. The best way is to
experiment!!!! As always! You put the large end in your mouth and BLOW!
When you start seeing purple stars with yellow halos, and the veins in
your head start to throb, you know the glaze is a little TOO THICK! :-)
I hook mine up to an old vacuum ( reverse end of the suction ) and let
the machine do the work. I'm too cheap to buy an air brush, but I keep
telling myself it might not be a bad investment. Mike

Actually, you don't really have to worry about this. As you might have
gathered by now from the posts on this subject, it takes a lot of air to
get anything to come out of one of these things. It's almost impossible
to suck hard enough and long enough to get anything to come up the tube.
By the way, if you're unclear on how this gizmo works, look at a Critter
sprayer or a Pasche "L" sprayer. They're the same mechanism, just with
a reservoir and a trigger mechanism on a compressor.

If you are not doing large amounts of spraying and want something easier to
use than a mouth sprayer, try your local hardware store ( i think in the
paint section) for a Preval Sprayer. It's a small pressurized cannister and
it comes with a small glass jar. It's not expensive, and ideal for accent
spraying. It's worth buying just for experimenting with spraying before
investing in a compressor and airbrush.
