we are a bit confused as to exactly what a cone looks
like when temperature is reached. i wonder if someone
with a website and the ability to post a picture would
be so kind as to show what a cone that has reached
it's temperature looks like. when i read a
description , i have a hard time knowing if that is
what i am looking at in front of me. thank you ginnyB

Ginny,
You can go to our web site at www.ortonceramic.com and find the
information that you want. The end point of the cone is always considered to
be when the tip of the cone reaches the 6 o'clock position or is almost
touching the kiln shelf or plaque holding the cone. This does not have to be
an exact type of thing since there would be only a couple of degrees
difference in temperature if the tip of the cone was under or over this
clock position by a small amount. If you have questions please contact me.
Tim Frederich, Orton Ceramic Foundation

tim frederich gave a good tip at the farm.
make a small, flat clay wall behind your cones, paint it with iron
oxide. you will see the cones against this tiny wall and they are
easy to see.
i actually envision making a cone pack with a tiny wall built up
painted with i.o.
like a little stage set. should work.
for those that cannot see cones..try this..see if it works.
then report back to clayart.

Hey Mel,
please, could you ask Tim if a back wall made up of a very dark
burning clay would give the same result.

I am wondering if this practice could effect the accuracy of the
cones? Ken Matsuzaki coats saggers with iron oxide and them places
shino pots in them. The iron migrates from the sagger surface and
give the shinos fire color.

Will try it, wonder if you make a separate wall if it could be reused? Not
lazy just trying to save a little bit of time...Jo

How about just using a tenmoku pot? Hate to waste the space.
I don't have problems seeing cones in my kiln. I always
look just before the next stoke and it is pretty clear by then.

Mayor Mel und all de oders:
I'm not sure if there was another start to this thread, but I have done just
this as an experiment for seeing cones in my cone 6 electric firing. I made
a "stage" of tan firing clay, washed the bottom with kiln wash and painted
on a crosshatch of Fe oxide. I could see the cones just fine. I could tell
no difference between the staged cones and the other cones next to pots as
far as bend is concerned. I fired at least twice to cone 6 with the stage
and it is doing fine though I made it too short to fit three cones with
their wire holders. Now that I have enough experience with trying to see
cones in my kiln, I think it is overkill (for me anyway).
I'm sure higher firing and redux firing are another story, though with a
similar ending?

Taylor,
I think it is a reduction atmosphere that makes the cones
difficult to see, combined with white hot temps.
Did you get a chance to peekat the cones in Tony's dragon? (Did
you take Tony some of Wacos best? Non-corn syrup Dr. Pepper? Give me a
Dr Pepper over a Coors anyday. ;-) )
My teacher always measured the finished of a firing, whether it
is gas, wood, or enamel, by pulling glazed test tiles. The cones,
more or less, were just marked for when the tiles should be pulled.

Anybody considered using a piece of soft brick stained
with Iron Oxide for the cone pack backdrop? I would be
reusable and it could be restained if the I.O. should
start burning off.

Victoria,
You should not use any oxide or other material on the cone. Any of these
materials can change the melting point of the cone. The color that Orton
puts in the cones is a water based product that burns out early and does not
affect the cone.
Lower firing cones that have RIO in them work because of the precise amount
in the formula and the blending process.
Respectfully,
Tim

For your application, you could do some tests to see just how much an oxide
MIGHT affect the melt of the cone, do some firings with treated and
untreated cones side by side.

I read the post in the archives from the first week in July.
Realize that looking at cones without proper eye protection will result in
eye damage (similar to looking directly at the sun).
I have used a pair of welding goggles to view my cone packs. They are
always easy to read. I fire to cone 10 in a high reduction atmosphere.
