brushing on over and under glazes. how to smooth this out.

Potter, Mark on tue 9 dec 03

I also am interested in brushing on under and over glazes, without so
much of that sticking feeling that the wet brush has when it hits the

I have no problem when using liberal amounts of say iron oxide or rutile
as an overglaze or underglaze, so long as both the brush and the
application amount are liberal in quantity.

But sometimes I do drawings as an underglaze for pots with a celadon or
clear overglaze. The brush tends to 'stick' obviously, and I'd like to
add something to my underglaze solution to smooth this out.

Is gum Arabic the answer to this?

Low fire commercial glazes are suspended in gum solution rather than
water. This allows for one to brush on the glaze rather than dipping.
I would recommend using gum for this type of procedure. Perhaps
someone else knows the exact amount. I would guess 100% gum
solution (if you buy it mixed with water already)

Why not Peace?
