    Looks like you are getting close. With those clay pavers and it appears a good bit of mortar on the outside, take your time drying the oven. Start with several very small fires or charcoal fires to get it to dry out.

    One thing that is very important. Do not mix up more mortar than you can use in about 5 minutes, for the first few batches. Or until you get a handle on how long it takes you to lay the bricks.

    It will set up much faster than you think.

    Thanks David!

    Yep, have read that many times but really didn n't want to risk it cracking so bought a 25l bucket...
    Also did ask the supplier of the mortar, who make and sell these oven kits as well, if it needed "baking" to harden/set and they said it didn't...
    They didn't recommend mixing the ht mortar mix with normal cement though...

    Also I have 100 or so full clay pavers..... What are my options?
    can I make it work without cutting ://
    Need to source more...


    Tx in advance
    You should look at the data sheet or instructions for your ht mortar. I presume ht stands for high temperature. If so it has been designed for around double the temperature that we fire to and probably contains high temperature aggregates that are not required for WFO temps. In addition it probably contains calcium aluminate cement which in conjunction with calcium silicate cement ( Portland, the normal builders cement) it will accelerate the hardening making working time for each batch of mortar really short. High temperature mortars also depend on their clay content being sintered ie being taken to a temperature sufficient to make them permanent (over 600 C)

    Second question, sure you can do it without cutting the pavers. You will just have bigger gaps on the outside which just requires more mortar to fill them. The Homebrew is a way better option IMO.

    And how happy are we that most of Aus gets little of that white stuff. I suppose it is what you grow with.

    Ooh I forgot to update. I called the cfs. They wanted to know wat I was so concerned abt. As long as there is a way to extinguish a fire and it's not left unattended and not used to burn household or garden waste, I don't think it's such a huge deal.
    I will have clearance at the front of the oven and yeah.... Jus was busy preparing a base for the build....
