Splits in the hearth..

Re: Splits in the hearth..

I think we've had some interesting discussion on the topic, so I'm happy to leave it at that if you guys are. My point with the topic was not to turn the world upside down or anything, just to relay some interesting (and different) information here. I get the sense some of the folks don't want to hear anything different from what they've been doing or what they've been told. I don't purport to be right here, just raise a different point of view from someone who appeared to be qualified to comment on the matter.

JB, please allow us some leeway to ramble as we discuss things on this forum. I appreciate your ideas and am earnestly interested in your feedback, especially as you build your low dome (which as best I can tell is uncharted territory in home ovens). There is not a 'one way' to make a brick oven. With the overlapping hearth component idea there are pros and cons, but until someone is reporting from experience we're just kicking around ideas (which I think is fun). If I was long winded in my discussion about this it was not because I have any passion against the idea you brought to the forum, just a passion for these ovens and the ideas behind their performance.

Please keep it coming.

Maybe not totally uncharted...
Kiwipete made a 36" oven with a 15" interior height

Re: Splits in the hearth..

I made our oven floor out of 12 by 12 by 2 inch tiles we procured for free by having the Penthouse Pet of the year interview the owner of a local pizza oven manufacturer. He gave us a bunch of tile offcuts which we used as an additional thermal layer before laying the full tiles on top. This all sits on 2 inches of calcium silicate insulation board.. Does anyone think I might have too much thermal mass in the floor? I added two rings to the dome in the last two days.. First two days I've hed to myself in two months..

Re: Splits in the hearth..

Hey Nick,
Can I check this again? Your floor is the 12x12x2 tiles that you scored. Did you do two layers, where you have 4" cooking floor mass set on 2" of calcium silicate insulation? Is that right? I don't think it's a problem, but you might not have had to add the extra mass. My (very bad) memory was that those tiles were thinner than 2". Either way, you're fine.

Hope all is well on the home front.

Nick,

Yer a dog, bro. Penthouse Pet of the Year, indeed. You did score, no doubt about it.

Don't think you're in any trouble in the mass department. Fire up might be slightly longer, but not much. Then again, you'll have all that heat for the breads you WILL be baking. Right?

15/36 = 0.4167
My 'Neapolitan' Pompeii is 18/42 = 0.4286

JB I plans 14(? if I'm remebering correctly)/42 = 0.3333
ljanmi2 has similar plans with a 36" (I believe he is aiming also for 14" height).

That's going to be uncharted. I'm hoping to hear more about his experience with that.
