I'm determined to get that nice, ever look in glazing & decided to go
with a spray setup. Air brushes seem a bit small & prone to clog, but
regular paint guns seem too large.
Anybody have input on a preferred delivery system for spray glazing?

This has gone round on the list many times, but I am sure you will find most
of us that have spraying requirements us a HVLP system (thats high volume
low pressure). This type of sprayer is available from many sources. We use a
gravity feed DeViliblis system which has carbide inserts in all the high
wear areas to prevent metal degradation by the air/glaze stream. I am quite
enamored of this system and the gravity feed works perfect with all our
glazes and under-glazes and can provide any spray pattern with appropriate
volume. My staff is quite happy with its ease of use. We have both inline
desicant filters as well as filter regulators on the air manifold at each
air station.
There are external pressurized pot systems available that have built in
stirring devices and you can have one pot and gun for each color that you
have. I know my colleague Bill Campbell has this type of system and has used
it exclusively for many years.
I my experience, the internal/external siphon mix systems that use a spray
handle/gun with a screw on liquid container are ill fitted to use for
glazing in that they wear out quickly, clog, and can be dangerous even with
proper air regulation. These sprayers are prone to quick failure IMHO.
As a side bar, we use a Paasche dry booth that exhausts to the outside
through filters. It uses a 3 HP motor and quite frankly, removes damn near
close to any and all overspray.

Hi, Jimmy.
Get yourself a Paasch glaze sprayer (you can find
two or three models in most ceramic supply
catalogues--pick the one that sounds best to meet
your individual needs.) You will also need to
build/buy yourself a spray booth vented to the
great outdoors. I love my spray set-up, but it
does take some time to learn how to use it. And I
don't like my glaze application to be too even,
either. But you'll get the hang of it and the look
you want if you're persistent.
Good luck and have fun,
Cindy Strnad

HI - suggest you check out Harborfreight.com and order their HVLP (Low
Pressure)
Gravity Feed Spray gun for $45.95. Item number 43430-75CA. It's great for glazing
with very little overspray or dust - and most important LOW pressure. It does not
have a carbide tip/assembly, but in a class room environment , used daily, it has
survived about 80 students over the last year or so - AND the price is Right!
I brought this spray gun to the attention of the Pottery teacher at Skyline
College last year. He bought on on my recommendation. In a class room setting, it
is used daily by many
students with no problems. I have six myself, two for glazing, two for painting
and two
spares. I was a long time (25+ years) Custom auto/motorcycle painter before
getting to my current LOVE - POTTERY and CLAY so I have the experience with many
many spray guns from Binks, DeVilbus, Pasche to whatever (All of those are very
expensive).
You can adjust this recommended gun from a 1/2 inch circle to a fan width of
about 6-9 inches. Trick is to put on WET coats (two) with about one minute wait
between coats. If you are applyi glaze that looks like a "powder coat" you are
dusting the glaze on, wasting it,and will not get 100% everytime results. Also
very difficult to handle after glazing. A WET coat is important!. Also you can
shade glazes with this gun. Very easy to do. This spray gun is easy to clean in
plain running water. The glaze should be strained and about the thickness of cream
for best results - it is important to not clog the gun, but it can be easily
cleaned.
Compressor of 1/2 to 1+ horse (plus recommended) can be used as long as you have
an a storage tank of at least 10 gallons - this is a MUST. Suggest do not buy
oiless or a combination compressor. You want one with a motor and compressor with
a drive belt between (runs much cooler). You do not need a high priced turbine
high flow - low pressure compressor. Harbor freight usually has what you need for
about $200 or so. Don't skimp on the compressor. Once you have one, you will
always find a new need for it. Actual pressure at the gun is about 5-6 pounds so
no or very little overspray and a very clean shop - also at least 80% of the glaze
gets to your creation so very little glaze loss. Sorry about the rambling -hope
this helps.

Hi Jimmy,
The compressor I used is in-fact a turbine system and becoming more and more
the choice among the wood working and metal professionals. The way I got
expose to it is through my wife's business. She is the General Manger of one
of Reader's Digest business unit. Some of the magazines she run are American
Wood Worker and Handyman. The editors of those magazines have suggested the
air turbine to me.
Here is some contact information:

Telephone: 845-266-4047
E-mail: bboxer@hvlp.com

The model I have is model 800 list price$950. I paid $700 including tax,
shipping and accessories. The next model down is probably around $400. It
comes with all the spray accessories (pipe, gun, and much more). Instead of
the big spray gun container, I got several smaller units so that I can
quickly switch from one glaze to the other.

I use an auto paint sprayer, it's not too big. It doesn't clog and it
doesn't cost load from a ceramics place. I also have an auto painter
detailer which is smaller. And an airbrush, but that's only go for detail.
I spray not only glaze but slip too. In my opinion you should go with the
auto sprayer, you'll never have to buy a new because you've out grown it.
Bought mine in college and still using it after years of spraying and
neglect.
