silica content in brick and mortar - 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.

  • silica content in brick and mortar

    I have become quite interested in building one of these ovens, and have been pricing out materials. While pricing out firebrick, I explained to him what I was doing and he warned me about the high silica content of the brick being a hazzard to cook food on, and told me that commercial refractory cement has atleast twelve different oxidants in it, and would not recemmend using any of it, and to try and find low silica bricks and special mortar. Browsing this site and the net I have found no mention of these concerns and am wondering if he is just being over cautious or whether there is some legitimacy to this?

    The concern with silica is the crystallization that takes place at much higher temperatures, about 1100 C I think, way higher than we fire to. It's quite safe for our application as far as I know.
    Kindled with zeal and fired with passion.

      crystiline silica is an air borne hazard

      ALL bricks and cement contain it, it's a basic component of sand etc. as far as i can see unless you plan to fire the bricks at over 1000c repeatedly and scrape off the tiny silica crystals and eat a few grams of it every day for years the worst you will get is a very painful kidney stone

      wear a dust mask when cutting the bricks, but most importantly wear steel caps, saftey glasses, look after your back and use power tools with care while building a pizza oven - these are the real dangers of building one.
