(Disclaimer:
I have never used a hot rock. I am not inclined at all to use hot rocks. I am simply curious, and this is something I've been turning over in my head for a ridiculously long time.)
Okay, question time. Why couldn't someone use a thermostat with a hot rock? Has anyone ever actually tried to regulate one? Of course everyone says, "Throw them away, they're from the devil!!" and I have seen how incredibly hot they get. But why couldn't they be regulated like any other heat source? I know probe placement would be tricky, but you could still hot-glue the probe securely. Or just use a rheostat.
Discuss!
