Using a vacuum is a nice way to avoid finger and tong marks, and get a
very smooth application.
You can make a vacuum holder using PVC pipe and fittings. I have made
them in a variety of configurations to accommodate differing pottery
shapes. The one for mugs is small and the one for platters has a long
handle so you don't get your hand in the glaze. I make a rubber washer
that slips over the cup side and I secure it with a bit of wire or a
hose clamp. The washer OD is bigger than the cup diameter and the ID
is smaller than the cup diameter. The washer sort of flares out and
makes the seal against the pot. I put a small hole in the side of the
end of the handle with a little rubber flap. That is used to release
the vacuum so you can get the pot off. The hose goes from the end of
the handle. I got a little valve from Graingers that allows you to
dial down the amount of vacuum. You don't need all that much. Also, I
made a "safety chamber" out of a 4' length of 4" PVC. It is set up so
that if the wand accidentally sucks some glaze it won't get to the
vacuum pump. That way you can completely immerse the thing without
worry. I can dip plates and platters with a single edgeways plunge
into a large bucket of glaze using a vacuum cup with a right angle
handle.
I might have sent this one to CM some years ago for the $10.
Happy glazing,
Gordon

Do you have a picture? I've been hoping to retrofit a pistol grip blow
gun I have. The thumb style one is hard on my arthritic thumbs! But the
pistol grip one has no hole for breaking the vacuum. A rubber flap
might do the trick..
