Dan depending on the size bowl you are looking to glaze I use an
irrigation syringe like one of these

clean
after use.I have used them in large salad and pasta bowls without a =
problem.
Just develop a quick rhythm .=20
I had also gotten from work a roller pump that wouldn't need to be

pumps
and perhaps could be substituted but I found it to be way more machine =
than
needed and the red or my preference the green bulb top irrigation =

did the job better with less mess and cost. Get the 2 piece ones with =

clear stem and the removable head. They are one of my favorite tools.

Don't know how it would work, but there are pumps designed for draining
pool covers and hot tubs that are about $50 around here - I got mine at
Home Depot for draining the hot tub. Doesn't need priming (it's a
self-primer).
Good luck!

Bruce!
Those small back yard swimming pools (Back in the eighties, Walmart,
$100.00 or so) came with a circulating pump. The pool, after a few
summers, bit the dust thanks to our rambunctious ten year old son but
the pump became a prime tool to glaze bowls,mugs etc. You can see it
in action on the Pottery page of my web site. Works like a
charm,still...

If you are glazing bowls, and use a ladle, you can press the back of
the ladle into the glaze in the bowl, displacing the glaze, thereby
raising the level very near the rim. This minimizes the amount of
glaze needed and remaining to get rid of. A rubber bulb might then
do the trick. Larger shapes could prove problematic.
You might think about adapting a hand operated bilge pump like those
used on small boats/kayaks. They don't require priming, are low
tech, and can handle a fair amount of volume quickly. You may have
to sprout an extra set of arms though.

Dan,
I wonder if you could use one of those sprayers that are simply
an air source blowing across the open end of a tube, sticking the tube
into to bowl?
Seems like too much trouble. If you have trouble pouring
the glaze out you could resist a small part of the outside rim and
pour there.
I usually dip my bowls so inside and outside are glazed at the same time.

Seems to me that using a glaze fountain solves the problem and you can get=

How about thinking low-tech instead? Depending on volume you need to
remove, would a simple rubber bulb-type "syringe" do? Some weird things
that come to mind are turkey basters (possibly modified with some plastic
tubing), rubber ear syringes (available at drug stores) or (do I even

I can't see paying hundreds of $$ for such a basic need...

Ben,
That's a cool idea. You could get plenty of deep knee bends in
too. The only drawback I can imagine is priming the tube to start
the flow. I remember seeing a siphon starting devise somewhere that
was a flexible bulb with a valve, but the valve would prevent the
glaze flowing back. Humm... There must be a way...

Dan,
Think siphon and "s" trap like under your sink.
If you have a flexible rubber hose coming from the bottom of a container of
glaze, as you lower the hose below the level in the glaze container glaze
will flow through the hose. In your case into a bowl that is being glazed.
When you raise the bowl back above the level of the glaze in the source
container (keeping the hose immersed in the glaze that is in the bowl) the
excess glaze will flow back until the system sucks air.
The glaze left could be swirled around to evenly distribute it.
Simple no pump idea.
Let me know if you try it. I think the glaze pattern is appealing.

Gordon,
In the setup I imaginesed, The tube comes out of the bottom of the glazes
bucket and is normally raised above the bucket to prevent the glaze from
draining out. No need to prime, just lower the hose and pot to be glazed
below the level of the glaze bucket and glaze will flow.
