Bisque temp miniumum for jewelry and sculptural work that won't be glazed but may be pit fired or stained.

I am relatively new to ceramics and have purchased a used kiln to fire beads, medallions, weed pockets and some sculptural objects. I don't plan to glaze although I may use engobe on some pieces before the bisque. I have some  engobe that for greenware.  I may try some pit firing with the objects once they have been bisqued.  Is there an ideal cone for this type of ware?

I think for pit firing you want it to be bisqued to 04.  If you're not going to pit fire I'd fire to the cone the clay matures at.  Bisqued stuff is very fragile still, firing to the proper cone will make it stronger.  Unfortunately you can't fire a pit fired piece to maturity because you'd lose the pit firing marks and whatnot. So theres a balance there between strength and beauty.

I successfully fired low fire clay, in a pit, after bisquing it to Cone 04.

But like Liam stated, you don't want the clay body to be vitrified. 

A groggy body will better be able to withstand the thermal shock as well.
