With the starburst pattern of coils under a platter,
bowl, or jar/vase, or the parallel coils beneath a
flat slab piece, I have never had any problem of
wadding, and I have fired all kinds of claybodies this
way.

Vince:

are the coils bisqued or green? Any filler like
vermiculite or grog in the coils? Do you fire the
green coils under the green platter and use again in
the glaze firing? Can they be re-used with other
vessels or are they peculiar to one item?

thanx for any clarification....

I explained all this thoroughly in a post just a few days ago. Use at least
60% grog or sand in the clay. Nestle the piece down slightly on the soft
clay so that it is perfectly evenly supported. Use fresh wads/coils in the
bisque and in the glaze firing. The coils are throw-away every time.
