This potter says, "By the end of the night, I had pretty much covered my entire work table. So I was done. I put all of my tiles on a plastic grid so they can dry more evenly. It doesn’t always work, but they seem to dry more evenly, with less warpage, when they have air drying them from all sides, top & bottom. It’s a little “trick” I learned from friend & tile-maker Mike Skiersch. It’s a simple “trick” using the plastic grids they put in suspended ceilings."
