I have a question for Richard Aerni and anyone else who sprays glazes in cold
winter areas:
When you use a spraybooth in winter, the typical spraybooth will exhaust all
kinds of nice warm air that you paid to heat. Have you figured out a way to
minimize this loss ... like (perhaps) sucking outside air through the booth?

First of all...apologies to the group for my post yesterday which no
doubt offended some. What can I say, I'm not perfect.
Next, about the spray booth. Mine is located in an unheated pole barn
next to the kiln, so I don't exhaust heated air except for when the kiln
is firing. I generally throw about 5 or 6 kilnloads of pots before
firing. When I'm ready to fire, in winter, I'll pull out the kiln car,
turn on a couple of burners and then work in the barn which barely stays
above freezing. It's a long couple of days work. Once the kiln is
loaded and firing, then the barn warms and I can work glazing the next
load in comfort. My recommendation for those working in cold climes
would be to locate the spray booth in an off area or small enclosed area
off the studio, so you can leave your pots and glazes in the heated
studio, and only carry one pot and your small glaze containers into the
spray area. It's not a perfect solution, but short of moving to Florida,
what is? Winter time for me is time to design new pieces, cast up
whatever plaster forms I may need, and generally throw near the wood
stove til I can't fit another finished pot in the studio.

I don`t think you could bring in the cold air from the outside without
building a very complex box system.
It may be more advantageous to build a set of clear plastic doors with seal
glove openings and to spray your work with the doors closed, turning on your
ventelation system for a few minutes just before opening the door to remove
your work. Again very expensive.
You could also try to install a heat exchanger. These cost somewhere near
1500.00
with instalation at $1000.00.

You put in make-up air ducts close to the spray booth so you don't draw
air from the studio. You put them close to front of you booth so you
pick up as little warm studio air as possible. You need more make-up air
than you have exhaust. You can also build your spray booth like a
sandblasting cabinet where the intake and exhaust are contained it the
cabinet with ducting going to and from the outside.

About this waste of heat...I put some of the blame on the design. I have a
Sugar Creek spray booth and wonder that they couldn't have put some kind of
damper on it so that while you are not spraying you don't lose heat or
receive more cold from outside. However, I find that it is better to
exhaust a little heat than to have a lot of cold coming my direction while
I am spraying. I do find that I have to be careful that it doesn't pull
smoke from the woodstove. Have to be careful not to have the studio too
tight. When I am not using it, I plug the hole with bubble wrap and then
put a piece of blue foamboard where the filter would go.
Now if I could just figure out why S C put the on/off switch up on the top
near the motor? It is a real pain to get to. I should probably pass
these thoughts onto Howard Axner so that he can take them in consideration
when he chooses a spray booth to carry. For the cost (500), you would
think SC could have offered some kind of exhaust pipe with a damper and a
switch that could be reached easily by those under six foot tall.

A simple solution would be to close the booth in like a sandblasting
cabinet and supply outside air through a plenum. Total exchange of air
and no wasted heat.

A spray booth without some air source would be dangerous. If you put a
marble in your hand and put the hose from a vacuum cleaner on you hand,
seal it tight then turn on the vacuum, the marble will stay in your
hand, because there is no air moving to push it through the hose. If
you build a spray booth in a sealed box, what ever you spray will end up
all over the box, and not be exhausted out the spray booth. A studio
cools down because outside air flows through the studio on it's way out
the spray booth. If you have an outside air source, like a window near
the spray booth you might not lose as much heat from the rest of the
room. If you build a sealed box with ductwork directly from the
outside, much larger than the ductwork exiting the spray booth it will
work. Doesn't have to be very expensive, but not free.
