Pit firing two

The last pit firing didn’t go as well as the first. Almost everything cracked. I may have to put off any more until the weather warms up again. In all likelihood the failures were on account of heat stress — some of which is to be expected in this kind of firing.
And I may just revert to electric smoking for the next five months, although the kiln is out in the garage which isn’t heated and has zero insulation as well. Only thing between the elements and the space is the siding.
I did use an old kiln shelf in this episode, in order to fit in some longer, flatter objects. I don’t think that had much to do with the cracking though.
Could you add some low-COE material to your clay to reduce the thermal shock?
