Clay Head Sculptures

My Introduction to Art students made clay sculptures this
spring. Our school has another art teacher who has the kilns in her
room. She fired the clay for us.
ALL the clay heads in the Alpine kiln blew up! The majority of
the heads in the electric kiln were fine. The color of the heads in the
Alpine kiln was sort of gold, even brownish; the color of the fired clay
heads in the electric kiln was basically white.
A few weeks before the other teacher fired the example clay head
I made; it came out perfectly. I used the same clay on the head I
made; the walls of the clay head were about the same as those of most of
the students. Three years ago my students did this project; most of the
heads were fired successfully; I also had a similar experience several
years earlier--they came out ok.
Would you assume that the clay was fired to too hot a
temperature in the Alpine? That the clay was fired too quickly--not
candled...? I know it could not have entirely been because of the
thickness of the walls of the clay, or mine would have blown up, too. I
would like to avoid this problem in the future.
The other teacher says that the problem was because they were
all too thick; some of them probably were too thick.
Any help would be appreciated.
