I'm Peter Reinhart! Ask Me Anything! Monday, February 15, 2016 7:00-8:00 pm EST

To kick off our AMA feature, we have invited author, chef and master bread maker and host of Pizza Quest, Peter Reinhart, to be our first host! Peter will be in the Forum on Monday, February 15th, from 7:00 - 8:00 pm EST. If you are unable to be online during the live session, you can post your questions in the sticky post. Peter will answer those questions during the live session on February 15th. You can view Peter's answers to your questions as well as what happened during the live session in the session thread.

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!

    Everyone seems to have a different refractory mortar mix they like to use.The mix I use is 1 part portland,1 part fireclay,1 part lime,and 3 parts sand.I' m building an outdoor fireplace this week.What mix's do you guys prefer to use?Is my mix a good one?Thanks!

    Re: opinnions needed!

    I used 3:2:1:1 sand fireclay portland lime. Seemed to work pretty well for me. My only mistake was that my sand isn't fine enough. It's the right material (pure white silica, beautiful white sand), but it's too big, #30. I had a hard time making a really smooth mortar for those tight gaps...although on the plus side it's probably a better aggregate for the fatter gaps than finer sand would be. I'm not sure what "better" means...more crack resistant?!

    Make sure your sand is the grain size you want, something smaller than #30 if you expect 1/8th inch or smaller gaps.

      Hi Flabuck
      I used the same as your preference and will continue to use it for future builds.
      It is cheap, easy to work, doesn't have gap thickness limitations and above all, it works and works well.

        I was only referring to the sand grain size, not the ratios...but I agree. Any variant on the homebrew is probably pretty reliable.

          Re: opinnions needed!

          O.k. bear with me.I,ve been a bricklayer for almost twenty years and to tell the truth I,ve never built a fireplace from scratch.I,ve built a WFO but no fireplace.So I have a couple of questions that maybe you guys could help me with.I obviously want it to radiate as much heat as possible(this is an outdoor fireplace by the way)so my question is how important are the dimensions?What I mean is how important are width,depth and height in relation to each other?And what about flue size and placement?I was just going to curve the back wall of the firebox up to meet the flue.I wasn't sure if the flue should hug the front or be placed more towards the back,or if it matters at all!I'm not able to make this thing as wide as I wanted so I wanted to make it deep.Maybe the deeper you make it the more likely most of your heat is going up the chimney.The six piece firebox kit that you can buy has nothing to it,I'ts square with a large flue centered directly above it.So I have a feeling that most of my questions don't matter but I thought I'd ask anyway cause I'm building this weekend.Thank for your help guys!

            I've built two fireplaces, and i think the best resource for this is the excellent rumford site. This plan, with a tall, angled firebox, an straight back with a curved throat, gives the best radiant heat results, as well as great draft and minimal emissions.

            My oven page in my signature shows my fireplace build, including a firebrick build of the curved rumford throat.

              Thanks for replying Dmun.You're illustration of the curved firebrick throat is going to help alot.

                Re: opinnions needed!

                Flabuck, Another trick to get more radiant heat out of a fireplace is to use an iron fireback. They are still available new cast and old ones can sometimes be found at second hand stores. In case you are not familiar with firebacks here's a link to a search at Amazon:

                Amazon.com: fireback cast iron

                Alot of the heat out of a Rumford type fireplace is thru reflection and direct from the fire. The heat from a iron fireback is almost all radiant. If the firebacks are too expensive (they certainly don't give them away) one can use a piece of heavy steel plate or recycle a bit of heavy equipment like a used track cleat off a dozer.

                Hope this helps,
