This is a really useful thread, as I'm sitting here waiting to peek in the kiln. I have a pretty basic setup, so I don't have a way to measure the temperature inside the kiln. Does anyone have tricks for gauging the temperature inside? When the kiln was pitch black inside I took out the second peep. I've heard of people doing the paper test, but I'm not too sure what temperature is represented by which results. I just took some paper and left it in for 10 seconds, and got a tiiiiiny bit of color change, barely tan, not brown. I have a small electric cress 23. Any idea what temp it might be if the top of the lid is warm? cool? thanks!
