It seems to me that insulating firebrick is diatomaceous earth + enough =
flux to bind it together when it is fired. Anyone know more about this? =
I was wondering if we might have a short-cut (or cheap-cut) here.

If you want insulating firebrick, the construction grade won't do. You
want the lighter ones that weigh 3 1/2 pounds, or less. Try a ceramic
supply house. They are used for building ceramic kilns.
