slip pump

Man, that seems like an awful long time to have glaze on the inside of a bowl, getting thicker, and thicker, and thicker....

If you thinned the glaze down enough to do this, it seems like you would saturate the pot.

So, I fill a big bowel with a liner glaze up to an inch from the top or
so. I swirl carefully getting a nice tight line on the lip. Then I suck
the glaze out with a piece of aquarium hose hooked to an electric pump
that pumps the glaze back into the glaze bucket. I then pour out the
remainder in a much more controlled way. Ideally It would be great to
suck enough out that I would be able to just mop up with an elephant
ear sponge.

Could someone suggest the kind of small pump I would need to explore
this method?

Thank you,

Dan

Dan: You can use the same method and pump we use for moving casting
slips with your glazes.

The best, and by far, THE BEST way to move slip or other liquids, in
your case with glaze, is with air operated diaphragm pumps. The
material never comes in contact with moving parts, or better put, the
moving parts of the pump, of which there are very few in a diaphragm
pump, do not contact the stuff that is being pumped. Hence you can move
stuff with pretty high viscosities and the mechanical parts of the pump
don't wear. Glaze and slip are abrasive. There are a few manufacturers
out there. We have used Wilden pumps for years and have moved gallons
of slip around our facility as well as sucking slip out of molds. You
can check the Thomas Register for address, or yellow pages for a Wilden
dealer near you.

Good luck!

I would like to try to pump the glazes out of large deep bowls rather
than pouring and making a mess, as well as improving coverage.

Hi Dan,

You might try a peristaltic pump--sometimes called a hose pump. They
are self priming and the abrasive glaze only touches the flexible
plastic tubing--not the seals or bearing or other innards that a more
traditional type of pump has.

Regards,

John.

About this method of removing glaze from a bowl, I would think that the
glaze would be in the bowl too long and build up quite a thickness that
might cause crawling on drying. It is my experience to pour just enough
glaze in the bowl to swirl around and then right out. Your method would
seem to put a lot of moisture in the walls of the bowl to inhibit any
absorption when glaze is applied to the outer surface.

Bonnie Staffel, must be getting bored being sick with all these posts to
Clayart. Lots better except for the lingering earache.
