'Charred' in the Bible

If it has been thrown into the fire for fuel, and the fire has consumed both of its ends and the middle section has been charred, is it suitable or useful for anything?

Notice this, even when it was complete, it was not useful and was not made into anything. How much less, after the fire has burned [part of] it and [the remainder of] it is charred, can it still be made into anything?
