fair faced brick and deep struck pointing are same thing?
Should be. Bricks are fired in a kiln, at least as hot as your BBQ pit.
A brick is 3.5" thick. They will easily crack. I would find another way.

The depth and width of a footer for a concrete pad will depend on various factors such as the load that will be placed on the pad, soil conditions, and local building codes. Generally, footers are often at least 12 inches deep and extend beyond the pad on each side by at least 6 inches. It is recommended to consult a structural engineer or local building authority for specific requirements for your project.
In "Cat on a Hot Tin Roof," Brick suffers from an undisclosed problem that is usually assumed to be homosexuality, although it's never specified. In most productions, Brick is played as not knowing this about himself, or as being deep in denial.
If you go to the monolithic dome site you will be able to check the size of footers for the over all size of your dome. Rev.Dick Freeman domeman3@earthlink.net
It all depends on what the post will be used for. In general 30 to 36 inches should be adequate to support a 4x4 post for a clothesline, a fence or a mailbox. Anything less than that and you most likely will have a problem with frost moving or lifting the post to the point where it will not be straight in the spring.
