My pyrometer is off site...but to put your mind at ease, the coil functions the same with or without the jug. Its only when operated for extended periods on high (10 minutes) or with the gap plates not truly parallel that you see the gap start to arc or become unsteady. On high the transformer puts out roughly 1kV at 250 mA in my replica. If heating is steady on one area of the plates pitting tends to occur and its this pitting that leads to arcing. Since heat rises and the gap is parallel to the ground plane the upper plate does tend to become a bit hotter than the lower. At low power levels, say 75 to 100 watts, the apparatus produces 6 to 8" sparks and can run for extended periods without the jug...

Jeff,
Do you think you will get an opportunity to run the Kinraide coil with a
thermometer in the hemispherical water can? It would be important to find
out if temperature is actually quenching the narrow plate gap or if there
are other factors at work.
