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.

  • diatomaceous earth under perlcrete

    I was rooting around in the insulation photo gallery and saw someone using a thick layer of diatomaceous earth on the top 2/3 of the dome before putting on the mortar/perlite insulation. Anyone have thoughts on what the logic is here?

    It turns out the DE is a decent insulator. Here is a table of thermal conductivity of different materials, nice to keep in your toolbox (pardon the pun) next time you need it's conductivity. Thermal Conductivity of some common Materials and Gases

    Maybe the guy had a swimming pool and had some DE laying around instead of perlite. I wouldn't recommend it, however. It's only half as good an insulator as perlite and that's not expanded perlite.

      Thanks for the reply Inwood. I think the swimming pool left overs is a pretty good guess. I got started building a 36" Pompeii after removing a ratty old chimney from a house during a remodel. I'm cutting it all out and dry stacking it now so I'm researching the next step. Thanks again.

        Insulating your oven

        The materials you use for your oven will be dictated by what is available in your area. I found a source for vermiculite in Fort Worth you might want to make a note of. You won't need DE.

        I bought zonolite/vermiculite masonry fill from Builder's Equipment and Supply, 320 Broadway Ave, Fort Worth, TX -817-332-2373- @ $13.95 per four cu. ft bag. That is a good price. I've read here that this product is coated with silicone to help the particles flow into the voids of concrete blocks after the wall is already built. Hence, there may be an issue with water absorption while making vermicrete. That wasn't a problem for me. The little bit of vermicrete I mixed was fine, I'm planning to pour it into my enclosure and put a top on it to keep it dry.

        Insulation is not the place to cut corners.

        If you are thinking about building a brick oven, my advice is Here.
        Our One Meter Pompeii Oven album is here.
        An album showing our Thermal Breaks is Here.

        I try to learn from my mistakes, and from yours when you give me a heads up.
