Perhaps is it time to let the cat out of the bag. Some years ago, I was flown down to St. Charles, MO to build an oven for a very large project. It appeared that the masons doing to bulk of the stonework would be there for a few years. I was there for a much shorter time to build a 4'x 5' oven to be incorporated into the entertainment kitchen along with a charcuterie.
One of the perks of going far afield to build ovens is meeting regional masons and learning/exchanging skill sets. A remarkable addition to my knowledge came about when we were ready to close the crown of the dome. Rick said it needed a 'Roman Keystone".
All arches and all domes need a keystone, the brick or stone that locks the entire structure into place.
A Roman keystone does this too, except it is cut from a rectangular brick. For arches, the keystone locks the side bricks in place and allows the removal of the arch form.
I began to adapt the idea to my round domes. It eliminates the last ring of slivered brick and allows for a measured finale. There. That's how it's done.
