End of the second day.  The firebox floor is complete, two more courses of brick to go on the side walls and three courses of brick to finish the back wall of the firebox.  We had Dana stand next to his creation to show the size of the fireplace.  For earlier photos http://www.dmstorrschimney.com/our-soot-stories/fireplace-firebox-construction-mansfield-day-2-con-t-
