I believe the bowl was iron, but orgone accumulators are supposed to be a mix of several materials. I didn't examine it closely because we were actually very busy preparing for an election at the time, although I was sitting for the entire time I used it. As far as I could tell, it wasn't charged or connected to anything. If you're curious about it you could try building one of your own to see what happens, although I haven't gone this far. After I took it off my friend told me that I was using it incorrectly and that I needed to be more cautious. Who knows, the entire thing might have just been some kind of placebo effect, but if you do actually build one and find that it works, make sure to proceed with caution.
