Ed,
This is a quick response -- with more to come later. I just wanted to say what a great-looking oven you have built, and that we are pleased to have you in our group. Nice idea for the form; as the Brits would say, well done, or in Italian complimenti.

Would you be happy to start a new thread under Pompeii Oven construction? I think people would enjoy hearing more about your construction, and this thread is already pretty long and full of information.

Also, please feel free to post as many photos as you have in the Photo Gallery.

Welcome aboard.
James

Who do you think would win in a no holds barred cage fight between Dmun and Ed? Both of you guys live on a plane of expertise upon which I can only cast covetous glances.

Hey this is great: It looks like your elements fit together better than mine did because they came out of standardized moulds. Yes, my triangles all had a seven and a half degree angle on the sides, and it seemed like the right fit.

Now if only we could get someone with connections in the refractory industry (hint, hint) to get the two styles of tapered triangle bricks cast that you need for this project. I really like the brick look.

Did you really assemble without mortar? That's WAY impressive. Mine would have fallen into a heap without refractory mortar. Keep the pictures coming: We would like to see your door and vent details.

Your project looks really good.

You know I do have a kiln, I could fill my molds with earthware clay which is fired to cone 8-10 2000-2300 deg. and has a high shock resistance. It obviously can tolerate high temps, and costs approx. 34 cents per pound. The triangles would easily fit into the kiln and the density is comparable with firebrick. Can you see any downsides?

P.S. Depending on the clay used it would be between bright white all the way to deep red in color and many colors in between. I could also put a pattern into the mold to give it a brick look( or smiley faces,pizzas etc). The only thing I am thinking is that clay shrinks between 10-20 percent when drying so my molds would have to be made larger in order to keep the 36" inner chamber. Thoughts?

Nick,
Are you having one of those "Mongo is just a pawn in the big game of life" moments? I am really enjoying seeing all of this fly by. Ed and David, keep going.

DMUN. The way you cut and reassembled your flue tiles.. How heavy would you estimate the whole rig to be including the eight inch piece on top.. How strong are the joins? I'm trying to figure a way to support the weight of my flue from above, as my vent will be suspended.. I haven't been able to find flue tile in any significant length.. The only similar clay tube is a terracotta sewer pipe, and I doubt it's ability to withstand high heat.

Can't you just cut the standard square/rectangular fire brick
into a wedge shape to build a dome? This way there's no need to cut or precast a triangle piece. Seems to me putting together a dome using square/rectantular pieces is more error tollerent (deviations in measurement and motar thickness).

I don't know how I missed this thread for so long, but my lord what amazing work! I sat down this morning with my coffee to do quick bit of research for my project and stumbled across this. Read the whole thing start to finish and now my wife is worried we'll be late for Easter brunch at her sisters! LOL Thanks for sharing, I am humbled.
