The reduction that I do at high temperatures is very light and there is
just barely a wisp of flame at my bottom side port, about 1/3 of the way
up the kiln. At cone 9 the kiln is put into strict oxidation and allowed
to go to 10 without any pressure. This does wonders for copper reds and
probably clears other glazes as well. Would I NOT reduce all the way to
cone 9? No, that light reduction is important to glazes like Spodumene
which will get a very unpleasant surface if it is allowed to go into
oxidation for any period of time between cone 012 ( or wherever you
begin body reduction) and cone 9.
I am saying that a heavy reduction at cones 6 to 9 is a waste of time.
I used to fire that way.
Now I get better results by beginning reduction at cone 012, very heavy
for 1 1/2 hours, then light all the way to cone 9 then clear to cone 10.
The glazes are much nicer.

Am I right in thinking that you start reduction at cone 012 up to cone 6,
then very light to cone 9, then no reduction to cone 10? I have been
experimenting in copper reds, with some success but would like to try this.
This would also lesson the gas bill.
