Artificial Fulgurites

Many months ago while browsing youtube for crazy stuff people do with electricity, I stumbled upon this crazy guy making fulgurites with what looks like 4 microwave over transformers and a couple capacitors wired together.

I also found these guys using some insane 12 kV at 1.3 amp power supply.

And this guy with a 12kV 600mA supply he constructed out of a bunch of microwave over transformers that he keeps sunk in mineral oil. (melting sand into glass inside a cardboard box).

So once we got the pole pig running with a space heater as a resistive ballast, I had to give it a try. We tried "play-sand" in plastic buckets, and eventually moved up to quartz sand in terracotta pots. Here is a short video of the process:
