i have some general rules about shelf placement
in a fuel fired kiln.
1. leave space, as much as you can manage.
2. stagger whenever you can. (not you.)
3. leave at least a thumb width between pots.
4. if you have to place shelves together, common
surface, do it near the top of the kiln.
5. the more shelves you put in a kiln, the longer
it takes to fire. firing to temp involves getting the
entire inside of the kiln to temp. pots, and their inside
space, shelves, supports, and inner face of the kiln.
the more that is in the kiln, the longer and more fuel
it takes.
6. mentally think `am i making heat flow dams?`
look at your stacking, does it allow the flow of
reduction and heat through the kiln?
7. in my opinion, in a gas kiln, a bag wall is usually
just a heat dam. i get rid of them.
8. learn how the kiln fires, hot spots, cold areas.
move your gas around, high gas, low gas, high on one
burner, low on the other. once a year, place extra
cone packs around your kiln. check things out.
9. if you can, fire down for a few hours. wonderful
things happen during the cooling.
10. if your kiln stalls, figure out what is wrong. make
changes, try things, don't just sit there and say...`well
that damn thing always stalls.`
11. nothing on the stack, no caps, rain hoods etc.
keep it clean and free. snow and rain do not hurt the stack.
forget it.
action and charting always help when firing a fuel kiln.
remember you are `going to war`. be awake.

Mel,
"7. in my opinion, in a gas kiln, a bag wall is usually

How do you explain your choice in a downdraft?
