Ask Me Anything New Forum Feature

You will notice a new forum at the top of the main page called, "Ask Me Anything". This forum will be used for live one hour "Ask Me Anything" (AMA) sessions hosted by people who are knowledgeable in different areas pertaining to wood fired ovens. How it works:
- Each AMA will have a "sticky" thread where the community can post questions they would like answered during the live session. This will allow everyone to participate even if you can't be online for the live session. These questions will not be answered by the host until the live AMA; if you need an answer quickly, you should post it in the appropriate Forum area for the community to respond.
- Another thread will be posted for the live AMA. Registered users who are logged in during the live session can interact with the host by asking questions and receiving responses.
- The live thread will remain in the AMA forum to view after the session.

We hope you enjoy this new feature! Please let us know if there is a topic that you'd like to have as an AMA and we'll look for a host!

  • Sand for refractory mortar

    Hi, I midway through my build of a 43" WFO using Forno Bravo instructions, and am now commencing the first course of my dome. I have sourced some materials from Little Hampton Brick, but have a question regarding the refractory mortar.

    The instructions list a "mesh sand" and Littlehampton state a "foundry sand". I get conflicting advice from suppliers as to what these are. Can someone clarify the type of sand needed to mortar the dome. Will "brickies sand" be OK or does the type of sand not matter too much?

    I don't want to do the hard yards with the dome with incorrect material.

    Firstly I'd better say that I used "poor mans mortar" but aggregate is aggregate.
    That "Mesh sand" bit sounds like its been graded and washed?
    I didn't use ordinary sand as the lot I had had been lying in a pile in the yard and was polluted by leaves and dirt. I used washed /graded sand sold by the 20 kg bag...2 maybe 3 in total. I only mixed the mortar in small batches using a 20 lte drum, paint stirrer on a drill so there's no waste.

    Regards Dave

      Thanks Dave,
      I appreciate the advice. The use of bucket and paint mixer has been a top idea. I have now completed the first course and commenced the second course and opening. Have taken advantage of the great Autumn Adelaide weather by taking time off work. Keen to get more done. I will post some photos soon. Thanks to all who are on the forum, it helps clarify so many points.
