I have just lost two large forms to slip trailing detail. They were partly
thrown and slab constructed. I have done this before using a commercially
prepared black stoneware body with no problem, however, these were
constructed using a white stoneware (also commercially prepared). I suspect
that the cause could be a
combination of the walls not being thick enough to absorb the additional
moisture from the slip, the clay body being too fine and dense or not
strong enough for construction, and/or that the slip itself could have been
thicker with less water. The slip was applied at a little past leatherhard
stage. It didn't take long for the walls to slump, crack and finally ugh!
Can this be corrected by any or all of the following:
1. Throwing thicker walls
2. Adding grog to the clay body
3. Instead of water, add vinegar to the slip (same clay body)
4. Apply slip at a more bone dry stage
Or would would any of you with this experience have any other method or
tips that would remedy this problem. Help!

Dear Marie, Try doing your slip trailing while the pieces are still wet.
