Yes, the key for burning many of them is to stack them so that there are no air gaps between the bricks. I ran 13 BioBricks in the Castine this way without issue.If you load all 6: 3 E-W and 3 N-S on top. No more than an inch space between every 2 bricks. Shut air down at 300F.
One fire starter between 2 lower bricks.
