firing 5/6 full

Allison Stelter on thu 4 dec 97


I'm interested in finding out possible consequences of gas firing a load
that
is not full by a shelf load. Also, how much space do you leave between
pots. I'm firing to cone 5 and I'm usually trying to cram my loads in to
pack as much as I can. Is it better to leave some space for more even flow?

Thanks, Allison

Allison,

My experience is that it does not hurt anything to fire a kiln
that is less than full. It merely wastes a bit of fuel. Maybe.
I used to stack the kiln as full as possible, in the belief that
somehow that helped "reduction" - that's what I was taught in
the beginning. However, I don't believe it is true at all, and in
fact stack much more loosely now, and find that firings are more
even and predictable if the shelves are staggered and the work
not crammed in with barely expansion room. You don't say what
kind of firings or kilns you are using, but whatever kind, in my
experience you need to allow the heat to circulate, not block it
by either shelf or pots.

Just spread the charge out to fill the whole Kiln, don't just leave out
a shelf. Then you'll get an even firing.
