Thanks Gene, that is interesting. Maybe I should have asked about your
wadding composition before I had replied to your original post.

I've heard of one who used unfired thrown stoneware bowls for their salt,
they melted almost completely! I suppose a high alumina mixture might react
differently than the clay. Is that the case here? I have always used small
fired thrown stoneware bowls in my kiln. I have some nicely glazed sake
cups as a result.

I will experiment a bit with the two waddings that I use in my next firing.
