Roxanne,
Howdy! Look in the paint sprayer department of Home Depot for a
disposable spray unit. It has a glass jar, a plastic syphon, and canned
air. It works for acrylic, and oil based paint so why not glazes? In fact,
one of my students has been using it for terra sigs. The starter kit is
around six dollars and there are replacable air cans for around two.

John, that was exactly my experience with them as well. But I did use them
for spraying a thin mixture of water and oxide or stain for years.

The disposable sprayers are called Preval sprayers. They come in a smallish
white box, & are often tucked up on the top shelf in the paint section at
Home Depot. Sometimes takes persistence to find them....I've used them for
underglazes, terra sig & ferric chloride.....very handy.

Has anybody actually sprayed glaze with one of these? I screen my glazes
through 80 mesh, but the only time I tried one of these it plugged up in
about a second and a half.

I use a Paasche Airbrush sprayer to spray all my glazes. It was a bit
pricey but it NEVER has clogged up on me and it has very few wear parts on
or in it. It is a real gem with many different sized nozzles you can buy.
The sprayer is available with a non-breakable metal cannister to hold glaze.
I also have to say the customer service people for the company are top
notch. I had to replace one of the parts due to damage which occured when I
lent it to someone and I had the replacement part within a couple days and
it was not expensive. They have a website if anyone is interested I just
can't remember what it is but search through someone like google.com. Hope
this is helpful to people researching glaze sprayers.

I use an HVLP spray setup that came from Harbor Freight. On the box it
says HVLP Electric Spray Gun Kit SKU# 44677 Chicago Electric Power
Tools. Made in Taiwan.
This kit consists of a spraygun, a plastic tank on which to mount the
essentially plastic spray gun unit, an air hose, a service wrench, and a
combination toolbox/motor/turbine compressor. What all this means is
when it is on, it is pumping air. There is no holding tank. The spray
nozzle can manage a variety of viscosities of materials. I use it
extensively in my work. It works extremely well. Biggest shortcoming??
Blows a lot of glaze, contol is adequate but not as precise as some of
the more expensive guns.
They are fairly inexpensive through Harbor Freight, though I cannot
remember exactly what I paid for this one - less than $100 for the
whole setup I know. If you purchase one of these, I suggest you purchase
at the same time one or more additional spraygun units. I find it a real
nuisance when swapping glazes to have to stop, clean the gun, and then
pour up another glaze. If you are layering glazes, you definitely need
the additional spray tanks and sprayguns. As I recall, they were around
$15-16 each.
If you have a regular air compressor with a storage tank, you might want
to look at the HF HVLP sprayer with the toploading cup. Has a metal
sprayhandle, brass and chrome spray nozzle and parts, and a regualtor
and contol knob on the handle. I used one of these extensively when
working in a ceramics factory, and it performed and held up extremely
well. It cost $75 at HF.
Good Luck,

Hi,
I would like some recommendations for a sprayer suitable for glazing
(without having to dilute the glaze down to water), and an idea of the
size compressor needed. Right now I am using an airbrush where the glaze
is so diluted it takes forever to glaze, and a paint sprayer that spits
large droplets leaving a very rough surface. ANy help greatly appreciated.

Al -
As far as I know, the true HVLP turbine-driven spray systems are the best
choice for spraying undiluted glaze. You can find abundant information on
them online. Harborfreight.com has some inexpensive HVLP turbine-driven
systems that work very well with glaze. A number of Clayart members use
them, and report very favorably on their performance.
My March, 2003 Tooltimes column in Clay Times magazine is about spray
equipment, and I talk about HVLP systems. For what you need, avoid the HVLP
conversion guns that work on a normal compressor, and regulate the pressure
down right at the gun.
Good luck -

Hi Al,
I use a Critter spray gun. It was originally designed to spray adhesive,
lacquers and paint for woodworking. It costs about $45.00. I use a small
compressor, (maximum psi120.) The compressor cost about $120.00. The Critter is
great because you do not have to dilute the glaze at all. The Critter uses
regular mason jars. It is so easy and quick to change glazes. You can use regular
mason jars to mix and store your glazes in. It is great for 100 gram test
batches. It has an adjustable nozzle, which controls the spray pattern. Spare
parts are sold separately at a reasonable cost. I have other more expensive
spray guns, but this one is the best. I only use a 30-50 mesh sieve with most of
my glazes and the Critter spray gun does not have a problem with the particle
size.

Al I have been using the Critter spray gun for a couple of years and quite
like it. It uses a one pint mason jar for the glaze container, and will
spray uniformly over a large range of glaze thicknesses. It is available
from Axner's, Big Ceramic Store, and probably lots of other online sources.

the Harbor Freight sprayer John refers to is item #43430 and i have seen it
for as low as $40 at the retail stores now (i also paid $75 for mine 3
years ago)and the nice thing about this one is you can buy a larger nozzle
for it with a 2.2 mm orifice, even better for spraying thick glazes. I keep
my glazes almost as thick as a casting slip, especially the copper red, and
it never clogs the sprayer at all, as long as you sieve it regularly.

I have never used this, but it sounds just like what is being described.

An inexpensive glaze sprayer can be made by using a jar with a screw on
lid. Drill a hole in the lid (offset to one side) through which a rubber
grommet will fit.(Radio Shack sells them). The grommet should be the size
that will allow a plastic tube with an internal diameter of about 1/8" to
fit snugly. The tube should reach almost to the bottom of the jar and
stand proud of the lid 1/2" or so. Attach a blow gun to the lid with a
bracket made of aluminum angle with a hole drilled to accept the nozzle of
the gun. Usually the tip of the gun will unscrew so it will act as its own
attachment nut. Anchor the bracket to the lid of the jar with stainless
steel screws & nuts. Align the nozzle of the blow gun so that air will
pass over the plastic tube & draw a stream of glaze up the tube. Adjust
the height of the riser tube & the pressure from your compressor (mine is
a small 3/4hp Sears compressor I've had for 20 years) and glaze
consistency until you get a good spray of glaze. Mine cost $5 & works well.
