Fired Brick Clamp part1

This past Friday I put together an improvised brick firing clamp to burn some of the test bricks Ive been making. The bricks are 100% clay with no sand or cement added. They were dry pressed in my mechanical ram press. I started the fire slow to cook out the remaining water in the clay. I fired it from 6:00pm till midnight with scrap wood and then closed it up till morning to continue the burn.
