sawdust and pit firing

Hello. I have a question. Has anybody every pit or sawdust fired without
bisquing the work first? And if so, what sort of clay body were you
using? When I was at school, I would take everything to 022 just to make
sure that I would have something to turn in for my grade (100% success
rate). But this Lizella clay seems to do OK without bisquing the few times
I have tried it. I was just wondering if my results were a fluke -
will I always be this lucky?

Emily, it seems wiser to bisque, to keep losses low. But - they're your
pieces, and if you don't mind the risk, then keep at it until something
changes/explodes. Why not? Most primitives have no means of bisque
firing, and so of course they do not. Since we generally do have that
means, we use it. The loss rate of un-bisqued work depends on
many things, including ambient humidity, fuel, thickness/eveness
of ware, etc. And maybe luck.

If you introduce the heat to the work slowly, there's really no reason to
bisque. Before the invention of the electric kiln, many millions of pots
were fired this way, and probably still are. It's much more delicate than
bisqued work however, so be careful.

i've sawdust fired greenware high fire clay (that's all i work with) and for
a small pinch pot it was ok...usually they're too soft and breakable using 06
