This was glaze 17 in the grid. I made it wrong, the red clay equivalent to redart has too
low alumina. Because of this reason, I did it in Curries site than changed the kaolin to
the red clay.
Sieve and wash the ash twice. Sieve the soil in 30- 80 mesh screen. add CMC apply
thin and thick.
Was tested only ones!
