Refractory mortar setting - 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.

  • Refractory mortar setting


    I am building an oven in Denmark and have acquired some refractory mortar which I am starting to use.

    It is dry powder just to be mixed with water) but after curing the joints are still not very tough. If I use my nail I can scratch the joints. Also I forgot to cover it up one day when it was raining and the mortar became soft again but after drying up it became like before.

    Does this sound odd or is this a normal property of the mortar?

    I have attached the data sheet if it helps.

    Thank you for your input.

    It may be a heatset mortar so it won't harden until it is exposed to a specific temperature. Someone like Tscar will know better. Is there a brand name associated with the mortar then you can go online and find out more.

      it looks like a similar product to what i used. It gains full strength at 800 deg F and up. And, the mortar only need to hold the brick in place, the strength is really in the dome shape.

        Thank you very much for your replies, they have been very reassuring :-)

        I have now also spoken with the producer and they also told me that the mortar will not become hard and set fully until the oven has been running for at least 4-5 hours.

        Thanks again - this Forum has been a great help in all my planning :-)
