How Many Firebricks?

[wvachuska]

I successfully poured my hearth in mid August and then took some time off for last minute recreation before my children went back to school. I am going to pick up my firebricks this weekend, but am confused regarding the quantity needed. the materials list states that 100 are needed for the cooking surface and an additional 180 are needed for the dome. Does the 180 refer to the number of half bricks needed for the dome, or will I need 360 halves (my oven is going to have a 36 inch inside diameter)?

I did cad drawings for the 36 inch oven, and came up with 171 firebricks, not counting the entry arch. The pics of the cad drawings are here:

Each layer is shown separately, you can count them your self.

I made a 38" oven (20" dome height) and used approx 210 bricks. I just checked my order, and I ordered 280, and I still have 70 left over...
