YES!!!!!! And I will still have time to get a lovely brass plaque made to
mount on the board.
You are a creative genius.

ROFLMAL - I have to say - this really works for me. I don't know how many
potters will be at your show but at least they would enjoy the image
(painfully of course)...

P.S. I would love to hear how the show went...

pull them out, buff away the kiln wash.

mount them on a nice board.

title them:

On the good side, in my last glaze firing, the unglazed portions of
stoneware were all toasty and gorgeous. The bad thing is, areas in my old
updraft kiln that got extra heavy reduction, well...the pots and plates
in
those parts of the kiln came out covered in blisters and pinholes and
almost
a volcanic rock type texture in some spots. These defects were on glazes
I
have been using for years so I am 99% positive it was caused by over
reducing, starting with a 1 hour body reduction at cone 06, ending at a
heavy reduction for 30 minutes at cone 9-10. I even got red in copper
glazes
that are always green, so I know I reduced more than I ever have before
and
wont be doing that again. Nothing about this firing was different other
than
reducing more than my usual from 06 up till cone 9. The reduction i did
at
the end was the same as always.

My question is...
