well there are a few possible reasons.
#1 guess: the large flat surface area on the shelf caused a lot of tension as the piece shrank (10% or so).
#2 : 2 slabs stuck together, both different shapes (one flat with raised square, one bowl shaped) stuck together at the edges. Wanting to shrink at different rates/pulling apart, etc..
Of course there was always concern about something happening (as with every single piece that you fire)but I didn't think it would be that bad. it's really my first piece like that.
Maybe resting it on a bunch of clay marbles or rollers?
Maybe building a small wall between them (more like a box than 2 pancakes squished together)the walls could flex/bend a bit.
Chalk it up to learning experience and be grateful that Tiki Central is such a cool and forgiving place
