I initially start my fire with lump and wood splits until the pit is up to temp, then burn the mojobricks. If you require a fairly large fire to keep the temp up, then you will probably burn through them quicker than I do. I normally set them with the thinner long side down, with 1/2 of the brick in the hot coals to ignite them.
