I single fire all of my smaller work up to about 8" across. I make sure to
let the work dry after glazing for at least a day or two here in dry Utah
before firing. I don't do anything different than if it were a bisque load.
I keep all elements of my electric kiln on "low" for 2 hours and then fire
up as usual - all night on "medium" and then "high" in the morning to cone
6, then soak for 1/2 hour. Usually bisque and raw work are in the same
firing. The only difference for me in the finished work is that I may have
one or two more losers with defects in the surfaces of the once fired pieces
due to unwanted particles in the clay body. Often these defects that aren't
apparent in dry ware can be discovered in the bisque and dealt with then.
Thus, I once fire the smaller stuff figuring if there's a loser or two it's
not such as loss. But these losses are very minimal and the gains in time
and energy savings of once firing far outweighs them.
