seeing the cones

This topic has been around before, but I did think I could see the cones in
an oxidizing electric kiln. Unfortunately I can't., it's just a mass of red=
.
This is flying blind, even if the digital program is in the general
area.... Any suggestions? Lesley

Well Lesley;

A pair of glassblowers lenses mounted in a safety glass frme will help. =3D
In addition, a 24" length of (preferably) stainless steel tubing(say, =3D
1/2' diameter, any wall thickness) for blowing gently onto the cones =3D
will render them visible for a second or two. Do not inhale!

I keep both tools near my gas kiln at all times.

Cheers, Hank=3D

Here is an article on viewing witness cones. The article includes a
photo of a cone as seen through a peephole at cone 7. I tried to shoot a
photo of the cone with my cell phone, but the phone could not register
an imagine. So I used a Canon Rebel, covered with green #3 safety
glasses, to shoot the photo.

My theory was that if I could get a clear image with a camera, I would
no longer need to look into the peephole.

First, make sure you have the proper viewing eye wear.
If there is a pot or kiln post behind the cones, you will have a very
difficult time seeing them.
You need something behind them that is in contrast to the cones.
Two things that work for me - you have to carefully plan your loading.

Make certain there is a clear path behind the cones to either a heating
element or a horizontal joint between bricks. The hotter element or cooler
line in brick will be a contrast that will allow you to see when cones go
over.

I also blow through the spy hole onto the cones. Some say not to do this,
but I haven't seen anything negative from the practice. Blowing in air cool=
s
the edges and creates a darker line along the cone, making them easier to
see.

Some say shining a strong light onto the cones works.

we use a basting tube to blow through. this makes for a very strong wind
what is easy to get to it the cones.
works even in the worst fog.

I second Dan's use of a Basting Tube - a really safe option. Also, I use Ga=

Welders Goggles; they are designed to filter infra-red AND they fit over y=

ur glasses (if you wear 'em).=3D20

Jim has an old pair of goggles with dark lenses. These goggles were
designed for working with a torch. With those goggles, I can see right
through the flame and into the kiln. The cones stand out and I'm able
to tell where I am in the firing. Love those goggles.

For those doing lots of firing, spending years looking through spy holes,
especially at higher temperatures, proper eye ware is a must.
Goggles/glasses should provide protection from IR and UV radiation.

I also have dark glasses for this purpose that work great on the lower peep
but the top one is hazy and the glasses do nothing to clear it up. I have
tried putting pots right behind it to make it stand out but the atmosphere
prevents me from seeing the top peep unless I blow air on it...Liz Gowen

arc welding googles are simply too dark to actually see through at
those temperatures, thus rendering them ineffective. but it's not
like they don't offer UV/IR protection.

Please can we make one thing absolutely clear.=3D20
Green Glass GAS Welder's goggles are the ONLY ones to use looking at cones =

Arc welding goggles are NOT suitable at all!!!
