A masonry disk should work fine.
You must slowly and lightly contact the surface of the shelf.
The disk can cut easily into a cordierite shelf if you don't take care.

You can flip over the shelf to get the flat surface.
Use it for bottom or any other placement.

I use an angle grinder with one of the rubber
cups as backing for coarse sandpaper. As
opposed to a hard wheel this will lay flat on
the surface of the shelf and not gouge as
easily. And it does a good job of removing
glaze drips as well as kiln wash.
