Just to wrap up the adventures of the pseudo-Minoan pot:
I should add that the pots were "tumble stacked" since they wouldn't have fit with the traditional shelves system. They were separated by "wadding", the tan blobs in the top picture. My teacher has a theory that things fell in part because the wadding was freezing as we were applying it during the loading and it wasn't sticking properly. She then tried to glue them on until the glue froze up. The rest were applied with spit, which would have thawed well before the final collapse - but there was an early collapse in which the upper set of cones fell when the kiln was at about 200F - they took things apart to fix that, but one of the teacher's pots was broken. Ah, who knows.
