Big or small vermiculite? - Forno Bravo Forum: The Wood-Fired Oven Community



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.

  • Big or small vermiculite?

    I went to HD to see what they had in vermiculite. They had big bags of a small type or fine grade of vermiculite. It looked different than what I expected. I tried looking around the threads, but didn't see anything about the size of vermiculite. Am I looking for the larger size (to get that oatmeal mix) or will this finer grade work the same.

    HD had 4 cu ft bags of vermiculite? This is news.

    The small stuff will work as well as the large particles. The only thing we've been warned off from is the silicone treated vermiculite, and at least one user has used this successfully.

      Thanks dmun-

      I think they were 2 cu ft (at $17), They had perlite as well, in the garden center. Is there a difference in using perlite or vermiculite. Any advantages of one over the other (ease of mixing, insulation value)?

        Re: Big or small vermiculite?

        Perlite is a marginally better insulator but probably marginally more expensive. I prefer vermiculite because it does not break down on mixing as much as perlite so you don't lose volume. I found perlite also contains a proporttion of dust that is irritating when inhaled. The perlite, that I've used also tends to float in the mix making it more difficult to get a constant mix. I'm sure that both materials vary depending on their source, but these are the characteristics I've encountered.

          I used standard vermiculite from the garden store. I have had my oven up to full operating temp several times and have never felt the slightest bit of warmth. After 3 months there are no visible cracks or weak spots. I used around a 70/30 mix concrete/vermiculite (give or take). So far so good.
