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.

  • refractory castable for floor

    I have seen previous posts for potential use for castables for the pompeii floor. From reading the pompeii pdf, it says that low duty bricks contain about 50% silica and 30% alumina. The instructions also indicated to stay away from refractory insulating bricks because they will not absorb heat enough.

    That being said, there is a refractory insulating castable for sale on ebay [Pacocast 24 by Resco products] that has a similar silica/alumina ratio....BUT it is referred to as refractory insulating castable. So is this usable for the floor or dome?

    No. It's an insulating product, like a very expensive vermiculite concrete.

      Insulating castables are in most cases very soft, so abrasion would also be a big problem. The denser the better for the base.

        So if the chemistry is *about* the same how can you tell them apart.

          Way different " chemistry ". Instead of Chamotte or fired brick grog, or Andalusite , vermiculite is used, very lightweight aggregate. Insulating castables have bulk density in the 750 kg/m3 range vs 2000 kg/m3 and more for the dense grade. Even dense castable is a no no for the cooking surface as it always "chalky ", who wants to eat dust in their pizza? You can tell by looking at the dry mix compound, put a small cupfull in your hand and see if you can see hard aggregate or small little 'concertina' shaped vermiculite pieces. This is the expanded or exfoliated light weight product. Better off using fired tiles or pavers. Gee, I have learnt something in 30 years in the refractory game, who would have thunk..........
