Once upon a time, I pit fired some really nice pots my students had
done with out bisqueing them first-some of the forms were especially
nice, as is always the case-all were burnished-representing a
substantial time investment in some cases. The firing went
beautifully-great surface marks! We too had watched the Maria video and
some of the students sprinkled corn on the pit-(popcorn!). Some danced
around-very festive. We went home that night with the pots outside in
the pit, cooling.
Overnight, it rained-long story short-mud and ruined pots! This is
how I learned-the hard way-to always bisque-at a low temp, first!
Hope this helps! (or at least garners some redemption :-) on the list of
my art teacher mistakes)
