I'm going to try really hard to describe my vision of this glazing=20
process I seek. Perhaps If I describe the desired result you will have=20=
a completely different spin on it. But I can't help thinking this glaze=20=
extraction machine quest still has merits over the traditional glaze=20
fountain or even a large irrigation bulb-type extractor, which is=20
clever indeed. I worry that the glazes fountain, though efficiently=20
coating the interiors of vessels, would still leave a rough, drippy=20
glazed edge to clean up or scrape off.
Here's my vision:
Using a glaze liner that is the thickness of cream, I carefully and=20
pour the glaze into a bowl. Any size. I make sure that the bowl is=20
setting on a leveled surface. The glaze is poured in until the level is=20=
about an 1/4" from the top, a finished edge is created, I quickly reach=20=
for a a rigid clear tubular wand connected to clear flexible aquarium=20
hose that leads to my pump system. The clear wand and hose permits me=20
to monitor the speed of the glaze flow. I plunge the perforated tip of=20=
this extractor tube into the glaze without turning it on yet. When I=20
touch bottom I then step on a foot switch or variable speed controller=20=
that will quickly extract the glaze. The glaze is pumped back into the=20=
glaze bucket. The process leaves a mark on the bottom of the bowl that=20=
is quickly covered by the last flowing glaze from the sides of the=20
bowl. The result? A cleanly controlled edge at the top of the bowl. Not=20=
variations in thickness a very smooth coating with it thicker at the=20
bottom where you prefer it. Immaculate. I know that speed is of the=20
essence or the glaze will get too thick quickly, but I think I could do=20=
it. Well that's it. It's a bit of a long read, but If you can help me=20
with my invention I would appreciate it.
Let say that your previous feedback has been exemplary.

Dan in this case what you are looking for is a positive displacement ROLLER
pump. I had used these on the heart lung machine in the Operating room for
years. A clear plastic tube goes through a roller head assembly and as it
rotates draws up the fluid and pushes it out the other side. Don't know if
you'd have much luck finding a used one even though our pumps went to
centrifugal a while back they are still used in animal labs.
I looked on the web and there are several smaller models even some
on eBay .Looks like they are used for many things including liquid
fertilizer or pesticide. Prices didn't look to bad to give it a try.
Let us know
