^6 ash glaze gone wacko

I am presently teaching at a small college, where I have taken over
the ceramics area for just one semester. It (unlike my other college

Anyway, I'd rather start fresh than try to guess at what happened.
I'd like to mix more of the same, but there is no record of the recipe
on file, and the guy who came up with it is in the hospital and can't
help me.
