hot rock
Volcanic geological material
A hot rock is simply a rock that has been heated, often for therapeutic purposes like massage or sauna treatments, or for primitive cooking methods where food is placed on heated stones.
In geology, hot rock refers to geothermal formations—subsurface rock heated by magma that can be tapped for energy production.
The spa offered a hot rock massage.
Slang uses include a recently stolen diamond or other gemstone that's too risky to fence.
