  • Mortar or not to mortar

    I am preparing to lay my first chain of bricks for the dome. I have read that this chain should be mortared to the hearth and I have read that it should not as the mortar might adversely affect the thermal expansion of the dome. I will greatly appreciate any input.

        should the first course have mortar between the bricks or no mortar until second course?

          That's what I did. Mortared them together on the sides, but let them float on the base.

          Note that I built my dome around the floor, not on it - so mine are not mortared to the floor on the fronts either. Just mortared together in a ring.

            Thanks for the input. I think that I will mortar the sides only on the first chain as you did.
