Recently there was a question about making stilts.
Here are three formulas by John W Conrad from his book "Contemporary
Ceramic Formulas".

mullite 65 shrinkage @cone 11 3%
calcined kaolin 10 absorption 16%
ball clay 10
fine grog 10
talc 5
R136 shelves/posts
mullite 60 shrinkage @ cone 11 4.0%
calcined kaolin 20 absorption 16%
ball clay 10
talc 10
R137 shelves/posts
mullite 50 shrinkage @ cone 11 2.0%
calcined kaolin 20 absorption 18%
