Hi folks:
Who can advise me about a domestic devise for put my glazes by spraying of
these. I need to avoid that a large part of them run away to the air, I need
to save and prevent to breathe dust.

thanks
Rafael

Ola Rafael !
You can use a big plastic dustbin, cutting a kind of door in one side
(of course if it is round...), leaving just 10 cm (of dustbin) at the
bottom of the door to keep the glaze inside. It is easy to clean. Then
you put your pot in it and spray. It is cheaper than a professional
cabin...
I hope it will help you
Sincerely
Françoise

Rafael,
The best system is to build or buy a spray booth. That is a box on its
side, open at the front, in which you place a piece to be sprayed. A fan
pulls air through the front of the box and out through filters to remove
glaze overspray. The air should then be blown out of the studio through a
duct or vent.
Keeping spray pressure low helps reduce overspray and atomized glaze.
I hope this helps,

Rafael ,
Inexpensive Spray Booth
(All this is in US dollars and dimensions, but should be able to figure out).

I built a very inexpensive portable spray booth for HPLV Low pressure
spray of glazes per the following. Total cost about $30.00
All materials should be easily available at a local hardware store. Here
are the materials I used:

Materials:
One each: Bathroom or kitchen six inch exhaust fan (about, $10.00)
One each: Wiring and plug to connect fan to electrical plug receptacle
(about $4.00).
Two each: Furnace Filters (I used 20x24 inch - about $3.00 on sale)
One each: Expanded metal sheet with large diamond holes (about $3.00)
several feet (estimated 20 ft) of 1x 1 inch boards/sticks (anything
available - about $4.00)
Fiberboard/Cardboard or any thing available to cover the sides and
bottom of the spray booth (about $5.00)

Picture a box about 20 x 24 inch x 12 inch. Fabricate the box out of the
1x1 inch wood/board/sticks and nails/staples/whatever. Cover All sides
AND BOTTOM with fiberboard or cardboard (NOTE-IMPORTANT - the back must
be strong enough to support hold the fan) . In the back cut a hole in
the back and install the exhaust fan with the air blowing OUT so there
will be a negative flow through the box. Size and design the box so that
the filters can slide in (like a stove rack ) while near the very top
of the box. Place the expanded metal above the filters to support the
pottery being sprayed. Note that the expanded metal should be "fixed" to
the box with the filter opening designed so that the filters can slide
out for cleaning (like a oven rack). Do what you can to SEAL THE BOX to
make sure that the exhaust fan exhausts as much as possible. For the
"upper booth" I took a large cardboard box and cut it so I had two
sides, a back and a top. I placed this over the spray booth box.
Finally at the fan outlet I sealed it with a pillowcase to trap any
glaze that was missed by the filters. Any pottery that I spray is put
on a rotating table/wheel on top of the expanded metal base. I still use
a approved mask and spray about two/three coats of glaze for best
results. Then I get into shading. patterns, etc. This spray booth works
for me but no guarantees if it works for you as it does not have a high
negative airflow. That is one reason that it I only use low pressure and low
flow spray guns. Sam in Daly City CA , USA with Heavy Rain. Comments
appreciated. Surely other potters have built better. Let's hear from
you.

Bathroom\Kitchen exhast Fan? Somehow I don't think these would have the CFM
that would be required for a "safe" spray booth. The Fan in my spray booth
is 12" and sometimes I wonder if that is enough...

You might want to look at attic exhaust fans - the CFM is much higher, and
they can be purchased for $40 to $60 at Home Depot type places.

I bought from the Big ceramic store, I think ClayArt center had it too,
EZE spray gun. Except the need to change the connection to the air. I
can say, It is one of the very best deals I have had. It is so simple
that if you loose a part you can make it yourself.
If you need extra jars you take the lead off, use it above the lead of
a plastic jar that you made to, two holes one for the hose and one for
the air. So good and so simple that I would not waste my time on
building such a thing!
