Feri,
You are right that by painting one side of the cone it might change the
rate of the cones maturing.However I have not found that it makes any
difference in my firing. When I fired my gas kiln I had no problem seeing
the cones at a cone 10. However, as you discovered,in an electric kiln it
is often difficult to see the cones bend. I consider painting the cone
safer than puffing into the spy hole.I believe it was students at Alfred
who came up with this idea.
For a bisque firing there is no need to paint the cones. Only when the
kiln reaches white heat do the cones become difficult to see. I have had
no luck with dark glasses or welders glass. Mia in ABQ where the mornings
are finally cool.
