Mortar set time in cold weather - 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.

  • Mortar set time in cold weather

    Hi all,

    Anybody know how wet cold weather affects the set time of mortar? I'm planning on using the fireclay/lime/sand mix instead of Refmix. It was 36 degrees this morning. I'm not expecting warm weather anytime soon.

    Also, I'm planning on using a canopy and tarp to cover my work this fall, but I'm curious what effect rain would have on the mortar and floor of the oven if it got rained on during the occasional extreme weather here in WA State. I can envision the fireclay/sand mix used in setting the floor washing out, resulting in an uneven floor.

    Thanks for your thoughts.

    I know that using cold water to mix Heat Stop will keep it more workable a bit longer and it seems that working in cooler, humid weather does too ... but I'm not sure if that applies to all mortars.
    I've been working under a canopy but also using a tarp in bad weather. I monitor carefully, when it's tarped, for condensation. I find that, being under the canopy as well, it's easy to flip the tarp to the 'dry' side or adjust air flow even if it's pouring rain.

      Wait a min fire clay, lime and sand..no cement? If cement is just implied then the mix you are using (fire clay, lime, sand, cement) really doesn't "set" like regular mortar, it more like dries out. The rain will damage that mix when still soft but not after it has hardened and will wash away the fire clay/sand mix from the hearth. Not so much the cold but moisture will extend its drying time. It will be cured (gain its full strength) only after its been fired.

        Implied cement included in the mix is correct. Sorry, I was being lazy.

        It sounds like you do agree that the sand/clay mix under the floor would indeed wash out if rained on. I did set the oven floor today and used only fireclay. It will probably freeze tonight. I'm waiting to see if the bricks heave.

        Thanks for both your help!
