    When using high temperature mortar, mix with water only to a trowel able consistency. Soak each brick in water for 10 minutes minimum as this gives a better bond with the

    mortar. When using ceramic fibre ware long sleeves and a mask in case of allergies or irritation. The render on top of the ceramic fibre blanket should be 20 -30mm or thicker to have

    sufficient strength. Use wire mesh for reinforcing.


    All ovens from 1meter to 2meters should never be higher than 540mm from cooking surface. Ovens under 1meter internal should be half their width in height.

    The door height should be 63% of the ovens height (this is just a guide).


    A wooden template which can be moved around gradually as the dome is created.

    A 50mm piece of conduit which is secured to the centre of where the oven will sit. Every

    brick that is laid must touch the end of conduit. By using this method you can create a near perfect dome. The length of the conduit is determined by the size of oven you wish to build e.g., to build a one metre internal oven the conduit must be 500mm long (half the width).


    To build a dome oven cut your bricks in half then by having a very thin joint on the inside and opening the joints up at the back, you can create a dome effect. To speed up the heating and slow down the cooling of the oven, cover the dome with ceramic fibre 75mm thick. This prevents massive heat loss, in turn allowing the oven to heat up quicker and stay hot for longer.

    Building the oven on top of insulation fire brick (I.F.B) also makes the oven more efficient and prevents damage to the concrete slab (cracking and spalling).

    The flue is placed in front of the oven door, drawing the smoke away from your face. When the oven door is placed up against the door arch sealing the main chamber, this create maximum heat storage with the only loss of heat through the steel plate door (4-6mm preferably).

    Floor tiles should be placed inside loose so over time with wear and tear, any cracked or broken tiles may be replaced. Ash after a few uses will fill any gaps and act as an expansion joint.

  • This base is a 20mm cement sheet with 2 layers of 75mm

    Hebel, glued together with Hebel glue. The size of the base

    is 1500mm in width and 1800mm in length.

    You may also use a concrete slab 100mm thick minimum.

    Lay the internal insulation brick in position, note these are

    not glued or fix into position.

    Cut and lay the floor tiles on top of the insulation


    When in position grind any high lips down leaving a

    smooth joint, this will stop the peel catching on any


    Your ready to position the door arch template and lay the first corse

    of insulation brick in the dome.

  • If you build the door arch first its always good

    to lay 3 or 4 courses either side for support. By

    using a length of conduit youre able to build

    the dome 5 or 6 course high before the bricks

    start to slide.

    Measure the width of the opening left in the dome,

    then by cutting 2 to 3 pieces of wood you can create a


    By using a level make sure the height of the sand from

    the floor tile is at the correct height, this is governed

    by the width of the oven. Once you have the desired

    height compact and shape the sand, brickie sand is

    best for this as the clay in it gives a dense and firm


    Begin to lay the rest the halfs cutting the halves when


    Once you have finished building the dome, leave the

    brick work for an average of 4 hours. Pull the sand

    plug out and now you need to clean the inside while

    its not rock hard, a scraper, sponge and buck of water

    is easiest way.

  • Youre ready to build the flue arch, there are a couple ways to go about it here are two examples.

    With the brickwork in the oven complete its time to insulate the oven, ceramic blanket is the most efficient and cost

    effective way. Covering the dome with 3 layers of 25mm thick ceramic blanket, with a total thickness of 75mm. Make sure

    that the joints dont line up, The insulation will reduce the ovens temperature from 400 degrees to 35 degrees. Using bird

    wire wrap the oven keeping it firm to the ceramic blanket, by not allowing the mesh bulge it will make the render easier to


    Render the oven 20 to 30mm an easy mix is (1 Bag of cement, 2 bags Sydney sand, 1 bag of brickie sand) you may also add

    a liquid hardener for superior strength. Make sure the mix is thick and you are able to make a peak from it this will insure

    sufficient strength, leave the render for 20mins to an hour depending on the weather With a damp sponge rub it back

    smoothing out trowel marks, where the render meets the flue arch allow 2mm for expansion and contractions of the oven,

    this will avoid cracking as the blanket will absorb any movement of the brick oven. Your ready now for the first firing.


    When firing the oven for the first time heat beads are best. It is important to avoid flame impingement to the brick work. Light 3-5kg bag of heat beads outside the oven to avoid the flames touching the brick work. Once lit, using a shovel, toss them in spreading them around the perimeter. After 20minutes you can repeat the process 4 more times, tapping the heat beads with a bar or stick every 30 to 60 minutes will ensure good radiant heat. Allow about 6-8 hours before tossing in the first pieces of wood. Do Not let the oven cool, it is important to reach cooking temperature during the dry out. You are now ready to cook otherwise put the door on and let the oven bake in the retained heat for the next 2 days.


    To create the wooden templates needed you must first lay the desired shape,

    (combination of bricks) on top of a sheet of plywood with wooden or plastic packers

    5mm thick to mimic the mortar joints. Once the desired shape has been created and

    checked for alignment and centre, mark the shape out labelling each brick as well as

    mortar joints on plywood.

    By placing two pieces of plywood together then cutting it out with a jigsaw

    will give you matching pieces. Prop up the template with wedges at its base. Once

    the brick work has dried you can remove the wedges so the template may drop and

    be removed easily.

    With the door and flue arch the height can be adjusted by adding or removing

    standard straights (75mm thick brick). This must be taken into account as each

    individual tends to make their mortar joints different thickness and this affects the

    width and height of each arch.
