I loaded my kiln today for a glaze fire (it's a small top loading electric kiln - (18" dia X 18 " high int.), I hadn't really realised before I started loading but everything I was firing was very shallow, no tall stuff at all, I ran out of shelves (4) before I ran out of room in the kiln.
Usually i'm fiddling and faffing to get it all in and it looked a bit strange with 6 or 7 inches of spare space above the last pieces, so, I removed the top two shelves and used longer posts just to give everything more room (in height terms anyway).
Was I wasting my time? Will it make any noticeable difference to anything?
