The drying went smoothly, I think the problem comes from the tension on the base as you mention. It was fired directly on the shelf, and I hadn't thought of using a bed of silica sand. Sounds like what I was looking for. Btw, for what kind of pots would you use the silica sand? I've just seen it mentioned in another post about tile firing. It doesn't seem necessary for pieces like bowl and cups..?
And finally, do you think finely ground silica would do the job, or should it be more sand-like?
