The bricks that you require for the hearth will have to be fire bricks as they store the heat for the cooking process. You can buy them in building supply shops. If you want a cheaper option, you could take the bricks from an old storage heater. Note: Soak bricks before placing if you are going to use mud morter (same mud mix to create the inner layer of oven), on the oven floor instead of sand blinding. This will prevent the bricks from soaking the moisture from the mud and weaken the mix.
Lay the bricks starting from the door ope. Work your way to the back as you will see in the following pics. Follow the brick patterns shown.
Ensure that the joints between the bricks are butted against each other. We used the kiss and slide method between the side of the new brick against the previously placed one.
Check the level before and after tapping down the bricks. Make sure that all bricks are firmly tapped down with a rubber mallet. Use a piece of timber if you only have a normal hammer. This will protect the bricks.
