>I have a Bailey the same size as yours and get good results with the

>(1) Pilot overnight with peeps in and damper 3/4 closed. By morning the

>(2) In the morning, open damper fully, light both burners at 2 w.c.",
>blowers on full, and burner flaps closed or nearly closed, until the
>burners make a slight "bacon frying" sound.

>(3) At 800 degrees I adjust burners to 4 w.c." That is usually 30 min. to
>1 hour wait.
>
>(4) At 1000 degrees or so I adjust burners to 7 w.c.". That is usually 30
>min to 1 hour wait.

>(5) For copper reds I begin reduction at cone 01, for most glazes at 06.
>I create reduction by closing the damper about 3/4ths. Determination of
>final damper setting is made by watching the flame out the bottom peephole:
>I want a lazy but persistent licking flame there. You should also see
>intermittent licking flame past the damper. I leave this setting
>(sometimes having to make minor adjustments to the damper by watching the
>bottom peep flame) until cone 10 falls. For me this is usually about a 12
>hour firing, which is rather long for a kiln this small, but the results
>are good.

>For consistent copper reds it helps to relight the kiln at dull red and
>reduce heavily again for about 20 minutes.

>It is always a good idea to check your burner orifices to see if little
>insect critters have been at work plugging them up.

>Also, call Bailey and get advice from them. Good luck.
