A few weeks ago I experimented with cone viewing suggestions that
many of you had shared on Clayart about two years ago. I tried
welder's glasses, mirror, flash light, positioning ware behind the
cones, etc. I didn't try blowing on the cones or inserting a rod
into the peephole, because I wanted to use only the safest ideas.
My observations:
1. Ironically, positioning the cones close to the peephole makes
them difficult to see. They should be no closer than 8", no farther
than about 12".
2. Position the cones so that when viewed from the peephole, they
are silhouetted by an element on the opposite kiln wall.
3. The element that silhouettes the cones should be level with the
lower part of the cone. If the element is in line with the upper
part of the cone, you won't be able to see the cone when it bends.
4. If you use the three cone system, always have the higher
temperature cone on the same side in every firing. Otherwise you
can lose track of which cone is which.
5. Use firing safety glasses, available from kiln manufacturers.
They are only about $12 and make the cones much easier to see. At
cone 10, the kiln interior is bright yellow. But with the glasses,
I can easily make out the cones. (I also tried a welding mask, but
found no additional advantage over firing safety glasses.)
If you follow these suggestions, you should be able to see cones at
cone 10.
With best wishes,

I followed the cone viewing thread with interest and the
following solved my viewing porblems in my gas kiln:
I painted iron oxide wash on small posts and put them right
behind the cone packs. Works great!
Thanks to whoever gave this tip.
