Hay Crew,
So I'm making new cone packs for the re-fire and find enough cones for two=
sets of ^01, ^8, ^9, ^10, & ^11 and one ^01, ^9, ^10, & ^11. When I unload=
ed the first firing I found some cone packs still intact so what I'm wonder=
ing is if I can use the under fired cones along with the under fired pots a=
nd still get a relatively accurate reading because they have all had the sa=
me relative heat work. I'm ordering more cones tomorrow but they might not =
get here in time for door bricking so I wonder if anyone ever tried reusing=
under-fired cones in a pinch.

When they had NCECA in Columbus, one of the stops on the bus tour was
the Orton cone factory tour (one of the most fascinating tours you'll
ever go on, by the way). Some one asked the employee conducting the
tour that very question. His answer was that they had never done any
research on that, but why would anyone do that when cones are so cheap
and there's so much riding on the outcome?

It shouldn't make any difference.
Heck, I have routinely bisque-fired my cone packs for years.

Half of my first bisque in a new-to-me gas kiln underfired. I placed one o=
=3D
f the underfired cones next to a fresh one in the next firing. It was bent=
=3D
flat (but still cone shape=3D2C not a melted pool!) where the fresh cone w=
as=3D
just "touching its toes". =3D20
So as it is a measure of heatwork=3D2Cnot temperature this isn't surprising=
.
I'd use them as a guide for checking other parts of a firing having fired =
=3D
one with a fresh cone first.
