I see. Thanks for the clarification, and the offer to help, Jeff. I did find the Forno Bravo site and started reading there last night. Tons of info to absorb.
One of the things I find interesting is that the ideal situation concerning adobe for insulating properties in WFO's is the straw involved ,which partially burns away when the oven is fired, leaving a lighter weight stone with more porosity thusly creating better insulating properties. Why is the adobe now improved by loss of mass while a firebrick with less density (ie: lighter weight, more porous) not ideal for a floor?
I would think that type of brick would actually be better for the entire oven including the floor, so long as the underbase of the floor is thick and the entire oven covered in dense refractory cement. Perhaps the porosity in light-wieght as opposed to light-duty bricks is not the same animal. of course, that must be it..but why? Why?
For me, it doesn't add up in theory, reasoning, or any other fancy words I can think up, but in practice it appears by what you are telling me that I am totally off base. I'm one of those gotta see it to believe it gals.
I do love immersion training sessions especially hands on where it's in my face and proven to me-but I tend to doubt many things presented to me, since my brain has already convinced me of something else. Stupid, eh....but for me it's a right-on way of thinking, especially since I still don't know how my computer actually works (or my television, for that matter) and then I begin to doubt these things actually exist, or that one type of brick can be that much better than another!
On that note, I also do not want to build an oven that I'll have to then tear down cuz it's a piece of crappola!
Please chime in, everyone who has
experience, cuz I need some edumacation on this firebrick thing. Can you see how stubborn I am? LOL. Tell me why I am so wrong in my theory. I obviously don't get it.
Again, Jeff, I do think you answered all of this in your reply, but I need a good swift kick in the noggin' to loosen up some of these gosh-durned preconceived notions.-Reesa
