Vtech,
No I never load it until it's out of the oven, and cooled to room temp.

, I test my mine and see it produce >.500mA, but right after being poured ....
I made another one before going to bed. This time I used more sodium silicate (water glass) and just a bit of distilled water to mix with cement. I also added 2Tbsp of calcium carbonate and alum. I used twisted grounding copper wire, insulated on the end to prevent shorting with bottom.
