Hi Butch,
I quickly dip pieces that have all kinds of nooks & crannies that would be
difficult to sponge evenly. Sometimes I spray them with a spray bottle of
water.
Recently I have tried something else on a few things, with good results so
far. I call it Pre-dip. This is a mixture that has often been mentioned for
overglaze brushing to bring life & movement to a glaze, but I use a much
more diluted mixture for the Pre-dip.
1500 grams Gerstley Borate
200 grams rutile
50 grams titanium dioxide
in about 3 gallons of water. (I may add even more water next time) I fire
cone 7 oxidation, and if you fire cone 10, you may want less flux )
I tried this because I conjectured that it might prevent pinholing and
crawling, thinking the "pores" of the bisque would havejust a bit of flux in
them, and would result in a surface receptive to the glaze, I'm thinking it
would get a bit tacky early in the firing, and form a bond with the glaze.
I do like the results so far. I do a really fast dip, and if some areas
look they picked up too much, I rub a little off.
Good firings,
Ann Brink

Somehow I think you have a mistake.
I use soil in my glazes.
The dust is a ball milled soil.
I do not mean REAL DUSTY WARES.
Except crystal wares that I clean with SiC paper underwater - I do not
do any special dusting.

It is difficult to get into nooks & crannies by dipping. Two
advantages of sponging is that you are actually brushing stuff off of the
surface and the contact makes for a capillary action from the sponge to the
ware. Hey, it was my job for 3 years! :-) If you do it long enough,
you learn exactly hard to push against the ware and how fast you move your
sponge to get the proper loading of water. You need a good sponge.
If your sponge is disintegrating too quickly, it means you are pressing too
hard.
What I did at the work shop, for handles, ears and any kind of beads
on the pots, was take a calligraphy type bamboo brush, dip it in water and
apply it to the seams. This works really well.
