Has anyone ever taken a glazed ceramic piece and sandblasted off the glaze in order to use it as a mold?
Thanks,

Sort of..partially. I bought a couple of nice square plates at Cost Plus and sandblasted off the glaze; drilled vent holes (had to buy 2 glass/tile drill bits because the first one from Lowe's broke). I have kiln-washed one of them but haven't had a chance to try it yet. Will try to get a test done in a couple of days (other project going on right now) and let you know. I can't think why it wouldn't work. Supposedly you can even do it without removing the glaze if you put enough kiln wash on.

Like Rosanna suggested, just a light blast to rough up the surface so the kiln wash will stick.
go for it.
