Photo Galleries are back! Instructions below.

Dear forum users,
Thank you for your patience with the Photo galleries. We've got your galleries online!
We have finished writing a custom script to migrate the PhotoPlog to vBulletin5’s albums.

Unfortunately V-Bulletin killed the "Photoplogs" in their software upgrade which was unforeseen and we're the first development group to have written a script for getting the galleries back... that said, it took some time to reverse engineer the code and get the albums to move over seamlessly!

Forum users will be able to access their “PhotoPlog” images through their user profile page by clicking on the “Media” tab.
They will also be able to browse other albums by going to the albums page. (On the forum site, there is a link in the black bar beside “Forums” to the albums.)

In order for users to create an album please follow the steps below.
1) Go to user profile page and click “Media”
2) Click Add Photos
3) Enter Photo Gallery Title in the first field
4) Click Upload or Select from Photo Album to add photos
5) Click Post
6) Once posted, the album will be created as a “Topic” on the albums page for the public to see. The topic title will be the “Photo Gallery Title” they created before uploading their photos.

To create this migration path we used vBulletin5’s default album structure. Unfortunately, it won’t work like the “PhotoPlog” but is an album/gallery component on the forum now.

Dome Installation Video - Casa / Premio / Modena


For many of you who bought a modular oven, you may have asked how we put the domes together when we build them. For those of you considering one of our ovens, we shot a video to make your install easier.

Check it out on our You Tube Channel.


If the link doesn't work, simply go to You Tube and type Forno Bravo Channel. The video title is How to Set your Forno Bravo Oven Dome Pieces.

Thanks for participating in our Forum. We will have more video content available soon.

    Why do I need FB board? why not just use vermiculite or nothing at all and just put the fire brick on top of the concrete and vermiculite?

    Re: FB Board

    1. The structural slab isn't rated for 900+ degrees.
    2. Even if the slab were rated for that kind of temperature, the slab would act as a massive heat sink. It would take days to get your oven to temperature.
    3. Vermicrete is a good solution, and the early builders used it extensively. Lots of us still use it. As higher quality insulating materials became more widely available, recommendations changed.
    4. FB board or Insblok or whatever other ceramic fiber board is used cuts diwn on construction time. Drop the board on the hearth slab and you can set hearth bricks immediately. Vermicrete has to set, and vermiculite can hold a bunch if water.
    5. Insulating board does in two inches the work of five inches of vermicrete. Depending on your style, it could be aesthetically desirable to have a lower hearth.
    6. Shaping the board to fit your hearth is easier than trimming excess vermicrete or forming vermicrete. I much preferred using a utility knife on the board to the Sawzall on the vermicrete.

      thank you. When you say structural slab you are using that interchangeably with the vermicrete?

        Re: FB Board

        No, the structural slab is the base upon which you set either the vermicrete or board. Your post referred to using "nothing at all", so I thought that you might be thinking of not using insulation under the hearth.

            What about fire cast concrete? I was planing on using 3" of fire cast on top of a regular slab

              Re: FB Board

              Fire cast concrete is not insulation. Fire cast concrete will just add to the thermal mass of the floor it is the same as using two layers of firebrick in the original post. You need an insulation layer between the oven floor and the slab.

                Re: FB Board

                On the subject of FB board, which then will have two inches+ of brick oven floor on top of it, what is the best material to "fill" the space so that a stone countertop hearth will be a a same level as the mouth of the oven when the oven is finished?
                Do you pour vermiculite concrete around the FB board and oven floor bricks to within 1 and 1/2" of the top of the floor (or whatever the thickness of the expected countertop is)?
                Trying to get a leg up on future issues in my own build. Thanks!

                  Re: FB Board

                  What I did for the countertop was I put a row of pavers on top of a thin layer of mortar. You could carefully pour some concrete, but the pavers were a bit thicker than the FB and then I added around 3/4" mortar to support the countertop. This amount of mortar gives you a fair bit of 'play' to make sure the countertop is the right height and level. If you push, wiggle, and pound (with a rubber hammer) it oozes out of the way.

                    Mingy: Thanks for the suggestion. I like the KISS genius of it, and it has got to be more cost effective than using concrete.

                      Re: FB Board

                      Well, concrete is pretty cheap, but you have to form it, mix it up, etc., etc.. Especially in this situation, you'd have to be extra careful to not splash stuff around. I had some old pavers with chips, cutoffs, etc., and it worked out ok.

                        Re: FB Board

                        judging from the size of the FB board it appears that I need three sheets of it to underlay the brick on a 42" oven. is that correct?

                          Re: FB Board

                          I calculated 4 pieces for my oven (for what it may be worth. As I have not yet reached that stage of my construction, I'll defer to the more experienced.)
