Oh, Judgement Day=21

Cones measure =22heat work,=22 not =22temperature,=22 and therefore your =
original
consideration was flawed, regardless of where the cone points=21 A cone =
will go
down at a lower temperature when the work of the heat has been accomplished
(e.g., in a slower firing).

Anyway, according to the Skutt manual, it's 3:00.

Dear Clayarters,

Please don't think of me as stupid but I must ask this question.

After using cones for =22many years=22 and always considered the temperature=
to be
correct when the Guide Cone is down and the Firing Cone is pointing at
3.oo o'clock that the firing is over, soaking etc., taken into account. So
far my glazes have been OK using this method and I have never had a need to
question it.

But =22Shock Horror=22 I have been told I'm totaly wrong and that the Firing=
Cone
should always point to 5.oo o'clock and no less. =22Silly old coot=22 I was =
told
=22you should know that=22

I feel that the difference is very little in degrees C or F but it would be
nice to know. Us Old Folk shouldn't go to the Studio in the Sky with a doubt
in the mind ?? You never know StPeter may ask the question if I ever go
that way. But there are no kilns up there ???

I look forward to the words of wisdom.

Kind regards,

Brian C..
