So Far, So Good
This past week I have been redoing the trim for the oak tree tile mural after the initial attempt ended up in catastrophic warpage. The things I did different were: using fresh clay rather than recycled and letting the clay dry in the jig a bit before attempting to move it. I also pre-cut the trim to 8" while it was still a bit damp rather than fire it, then cut. So far, the side trim that was redone is looking like a winner.
The darker gray trim on the right was formed just last night and is darker because it still contains moisture. The lighter gray on the left was more several days ago and is pretty well thoroughly dry.
For the cap of the trim, I decided to reuse the already formed clay since that didn't warp as bad. I'll make a decision whether it will be useful after I do the bisque fire.
