I seemed to have underfired my bisque run to ^06. What am I risking by glazing and firing to ^6?

Post Body

I had some problems with a kiln setup. The ad hoc downdraft fan was hauling too much air which cooled my kiln for awhile and the schedule got kind of buggered up on the new control system.

I haven't got peep holes to see the cones so I didn't realize that the ⁰⁴ cone's hadn't sagged very far. They're kind of only slightly bent.

What am I risking going to glaze instead of refiring the bisque? Can I just rebisque the run and use the same cones to accumulate more heat work or are the cones unable to indicate cumulative heat work once they've already been fired?
