Recently I poured a clay slurry (reclaimed) into something like
a mold to dryout. The resulting "tile" seemed almost useable, it
sure made an exact copy of the containing material.
My thought would be that there would be a random arrangement
of those little platelett fellows that would minimize cracking and
The tiles we make are Stoneware (^10) decorative wall tiles.
Somehow I have come to think that poured tiles would be weaker
than slabbed or pressed tiles. Is this true? Does anybody out there
using molds for tiles? Are there related considerations?
working away here in northport, mi making and glazing tiles. all going
well but experiencing some 5% cracking during drying right now. that's
a new one for me. only the smallest tiles are doing this.

The slip cast tiles I have made tended to warp in drying and firing a bit
more that those that I press molded, but that could have to do with the
different clay bodies/thickness etc.
By the way, did you get the jpg. I sent you with my latest work?

We have been slip casting tiles for almost a year now and have had less
warpage and cracking than we had pressing them. The losses I've had are in
the glaze firing, cooling too fast to get the next batch going. I have to
learn about patience about once every two months, hoping it will stick

If I remember the original post correctly, the tiles were poured by using
slurry, which is not the same as casting slip. I've had good success with
casting very thin, small tiles - almost no warping or cracking... That's
one of the great advantage of casting slip.

Thanks for info. My idea is to keep a good studio
flexibility for making a few pieces of this size/shape
or that. I visualize using a single big bottom plate
like a table and use flexible strips as the side barriers.
The neat thing would be that the pieces could be
completely irregular - and could fit together like a
jigsaw puzzle if that's how the pieces will relate.
No, I did not see a JPG but I am switching between
computers these days, and have been erratic with
my time for ClayArt. The new computer is 8X
faster than my last, so I have had come up with ways
to slow it down.
You've got to make it over here to Northport, this is
just a beautiful spot. I hope to be able to get more
studio space this summer. Offer to sail you over
