Hello. Painting a stripe of iron oxide on the side of the cone helps make it
more visible in the kiln.

If it is a gas kiln simply reduce the gas pressure for a few seconds to let
the cones cool to a point slightly below the surrounding pots and they are
clearly visible.
If it is an electric a short puff of air through a steel tube connected to
a rubber hose will cool the cones enough to read them, just dont blow too
hard, and for gosh sakes dont inhale!!!!

Arnold et al:
I have been known to blow into the peep hole assuming I've opened the
damper a bit to relieve back pressure. I will quickly say that this is a
very bad idea because you can blow loose debris onto your work, and if
you're not paying attention and take a deep breath in front of the open
peep you can inhale very hot air and hurt yourself. It is a dangerous and
stupid idea--but it works.
The other thing I do is put a metal rod into the peep next to the
conepack. This cools the atmoshere around the pack and lets you see it
better. It only works until the metal heats up. It is risky because you
can knock over the pack--but it works, too.
ALWAYS WEAR EYE PROTECTION: I bought some welders glasses. They come in
fashionalbe colors and are not very expensive $3-$10.
Good luck,
Sharon in RI

When making up my cone holders, (cones pressed into clay) I brush one sharp
edge, and maybe the very tip of the cones with iron oxide. Then when the
firing is into stoneware temperatures, I go from reduction to oxidation for
a short time and blow on the cones with a small twelve inch long metal tube.
This makes the iron oxide show up as black against the heat of the interior.
After checking the cones I return to reduction atmosphere.

Easiest is to open the peep, aim a blow drier at the peep hole -from a
distance,
from a distance, don't melt the drier housing! - and the cones will be
easily visible.

Hello Arnold,
wear lightly tinted safety glasses and beam a =22radar lite=22 on the =
cones=3B
if you are reducing blow gently some air in the direction of the cones
and move your head from side to side.

These might be of use:
Several of our customers have found that laying a standard cone on its
side so that 2/3rds of it project over the edge of a piece of shelf on a
prop makes it more visible, something to do with horizontal lines being
easier to see than verticals.
When faced with a small spy hole and a 3 cone pack i.e. 7, 9, & 10 I
line them up facing the hole with 7 angled to the left, 9 to the right,
and 10 to the left. Then all I have to remember is whether or not 7 has
gone, this requires abstaining from falling down water until AFTER the
firing!

We sometimes blow gently into the peep. This will cause the edges of the
cone to go dark. You run the risk of blowing soft brick dust into the kiln
and possibly unto the pieces but it works well if the cones are close to the
peep.

Dear Steve,
If you place your cones horizontally they may be easier to see but
will not really be accurate. I use welder's glasses to view my cones
and don't have much trouble seeing them. Of course, if you are
firing in reduction you must clear the atmosphere first.
Best, Debby Grant in NH
Louis Katz on wed 12 may 99
Squirt cones with spritz bottle.
puff on cones with blast of air.
insert a 1/2 "metal rod next to the cones, but don't tip them over. The
metal will cool the cones making them visible.
place a horizontally lined object behind the cones.
Use a pyrometer
Think---slight differences. It helps.
BTW I am going to go to nomail soon.

There are goggles out there which work very well. Oddly enough, I have
found also that, when things are really problematic, using a flashlight
helps a great deal. Yes, this is at cone 10, when things are VERY bright,
and it does seem improbable, but for some reason it helps.

My kiln was located in the backyard, outdoors (central California) with
the door and spy hole facing north. I regularly used a mirror and
reflected sunlight into the spy hole to observe the cones very clearly.
Now teaching full time, if the time of day permits, I'll set up a mirror
outside, aiming sunlight spy hole high into the kiln room and use a second
mirror to reflect the light into the kiln. During the evening I wear
welding glasses and blow into the spy hole before glancing in to check the
cones. Hope these are useful strategies. Bob

Interesting that. I've found in practice that there is virtually no
difference between a cone "hanging vertical" and a conventional "cone
down". Kiln results have been the same, and that's the name of it isn't
it?

John -
Regardless of individual variations in eyesight, the minimum protection
acceptable should be a standard. I have tried viewing cones with
arc-welding glass, and cannot see a thing. As you know, the light produced
by an electric welding arc is about a zillion times brighter than the inside
of your kiln. Is it possible that the glass you are using is for gas
welding rather than for arc welding?
