On a couple of occasions I have had small stones (1/8" diameter or
smaller) to get into the claybodies that we mix up. The stones would make
themselves known to us only as we would unload the pots from a completed
glaze fire.. The stones would appear as a small, hard node just under the
glaze surface... We have probably had a dozen or so pieces to have this
defect in the past year or so. I do not know the source of these stones...
most probably one of the dry ingredients that goes into one of our
stoneware claybodies. Perhaps grog is the source of the stones. My
question is this.... Is there a quick, expedient method to sieve or filter
the dry clay ingredients prior to adding them into the clay mixer?
Best Wishes... Marshall

I use a crushed clay from a brick company in my state, Arkansas. It has
lots of stones the size you discribe, but I know they are there, so I
turn the clay into slip and run it through a piece of window screen.
Since all the stones are held back by the screen, I can then add dry
ingredients to the slip in my Walker mixer. Because this clay is only
crushed and not powdered I cannot get it through the seive dry, but you
mightbe able to. I would put a 50# bag of each of your ingredients
through a seive to see which one has the stones.
I saw a design for making a screen fixed into the bottom of a 5 gallon
bucket, now I can't find the reference. I think it might have been in a
Ceramics Monthly. Does anyone remember seeing it?

Yeah, I remember that article--I think it's been about 5 years back. I
can't find it either, but do remember it had to do with melting the
plastic bucket edge into the screen. That could be accomplished with a
small propane torch. Maybe heating the screen with the torch would be
enough to melt the plastic into the mesh. I think they used copper
screen. Sam

I remember that. You cut the plastic bucket in half (after
removing the bottom). Wrap a flexible screen around the hollow bottom.
Then, press the bottom part inside to hold the screen in the top half.
Bucket wouldn't be 5 gallon any longer, though-- more like 2 1/2.

I tried the melting into plastic bit with a small (4") white plastic
pipe. The process stank. It not only smelled, it did nto work well for
me. I now file the cut edges of the plastic, or
sand them (wearing a mask, wearing goggles, wearing a mask AND goggles)
and use epoxy to attach screen. Works.
