Regardless if my pieces are thin and small or large and thick, if I put them
on stilts ( prongs ) in a ^5 glaze firing .. they slump and the center comes
" up ".. I am trying to do porcelain inlay where the design is different on
top and bottom..........I want to glaze the bottom as part of the total
design ...but no matter where I put the prongs, the same thing seems to
happen.. slumping in the middle where the prongs have been !! Am I destine
to only one sided glazing ?? Any advice is appreciated !! LTDeane in

>All of my books say not to stilt porcelain or stoneware,because it will
always slump. I'll be anxious to learn if someone has found a way.
Actually, at the the piece is vitrified [or close to it]and doesn't need
glazing.

You might try firing to a higher bisque that your glaze to avoid the shrinking
on stilts. Then use gum to adhere the glaze. This was a technique used for
firing crystalline glazes early in this century. You could give it a try.
