spraying glazes using airbrush

updated mon 31 mar 97

 

Tiggerbus on sun 16 mar 97

I have a PAASCHE airbrush that I bought years ago to use in a painting
class and when I finally got it I read the instructions and it described
the usage primarily for cermaics. Well it did not tell what type of
things you could do for ceramics so I am assuming it would be used for
airbrushing glazes!

Has anyone used this method and what should I do about thinning the glaze
with out thinning color! Please email or post on the newsgroups, I am
patiently waiting the news (well sort of)!

thanks to all ,

I use the cheap "pitot" type airbrush ($15-$20 US from Woodworkers
Supply mail order). The glaze never crosses any moving parts and so I
never have corroded internal springs, needle valves, etc. I NEVER clean
them. I just leave them submerged in water, changing the water from time
to time. I screen glazes 100-200 mesh in small batches just before use.
I throw away the little jars and cut plastic cups down to about one and
one half inches and hold the cup in one hand and the airbrush in the
other with the siphon tube submerged in the glaze. I keep broken guitar
strings handy to clean the spray adjust and siphon tube. These
airbrushes last me about one year before something breaks. They work
okay for me from 10 to 40 lbs air pressure. At 40 pounds you can spray
some pretty thick stuff. The spray particles are uniform in size and
application is smooth.

DRAWBACK: The spray "cone" in not conical, but rather a double vortex.
So there is some deficiency in fine control.

I like them for what I do, which is applying glaze and patinae over
masked sections of my pots. I HIGHLY recommend them for gross to
moderately fine air application. I don't think they would be good for
fine to very fine work. But they are so cheap, its hard to resist trying
them out.

Dear Aimster, my wife uses the airbrush to spray on
underglazes and the spraygun to spray on glazes. I feel
that some of the glazes would be far to rough to put
through an airbrush, and may ruin it especially one as
good as your Paasche. In any event she reckons the
fluid you put through has to be very thin and rather do
a few coats than trying to put on one thick one. That is
when you get drips and other yuchy problems. She gets
some amazing effects with the airbrush, but she is the
artist and I am just the technician. Good luck from Ralph
in what is supposed to be one of the last weeks of
summer in PE SA.

Hi Amy...I used this airbrush to glaze my porcelain work for 10 yrs. I
tried, when I was starting to airbrush, using glazes that were sieved
through an 80 mesh screen and had nothing but trouble..clogged airbrush,
dripping, splotching etc...then I thined the glazes down so that they would
go through the air brush easier BUT with the very thin glazes and
airbrushing translucent porcelain work, I found that it took forever to get
enough glaze on the work so that it was glazed when fired and the water
just soaked into the fine pot and wet it before a sufficiant amt of glaze
would be applied....... SOOOO I got a 200 mesh screen and sieved all my
glazes through this very fine sieve. The glazes went through the air brush
just fine with no blotching, clogging or sputtering and I could use a glaze
that was of a good consistancy, not watered down etc. I found in my
experience that a finely sieved glaze did the trick. I got my 200 mesh
screen from a chemical company that screens fumes and toxins. You can
hardly see through it it is so fine. I am not sure where you are or if you
can purchase a finer screen than the 80 mesh but would try to fine one
somewhere for really fine results. It takes a month of sundays to sieve the
glaze but in the end it was well worth the time verses the aggravation of
the 80 mesh screen.
Hope this helps. As Always in Clay Peggy

Hmmmmm. I suppose that there are endless reasons why I shouldn't
do this, or why it won't work, but - when I have to spray a glaze,
I put a couple of cups in the blender, run it for a couple of
minutes...no clogs. At least, so far.
