Slumping (such a silly word) can be done in a day.  I fired up the kiln at 8:45 am (Auto, Med, Slump) and it was cool by 8pm.

This load is my first test to slump stringers on the wave form.  I could have put more, but wasn’t sure.  Next time, I will spend a little more time to space them properly to maximize the mold.
