A method invented by Elizabeth Priddy in Beaufort, NC ...works perfectly for me, but your results may vary.
The best 'trick' to non warping tiles lies in the way you make them more than how you dry them.
If you roll them out on a slab roller, make sure to roll across the grain then let it rest for a few minutes. I always have a piece of old bed sheet between the canvas and the clay in my slab roller. This way I can slide the clay horizontally rather than pick it up when I have to move it. Always slide the clay horizontally ... even if you are moving a single tile, slide it.
Cut the tiles leaving a border unused as the edges of your slab are most likely to have been moved.
Once you have them ready to dry, slide them onto a board ( I slide mine on pages from old phone books) and drop that board to the floor from waist high. Then leave them alone ... Do not touch, move, slide, test ... Nothing til they are leather hard.
You can even put them outside in the breeze and sun and they won't warp.
It works every time for me and I hope it works for others too.
