Sounds like my kid who wondered if an electric burner on the stove was hot even if it wasn’t glowing red. So he put his hand on it and found out right quick.
Stoves?
We had a wood stove with a steel ash breaker that was cruved at the end, a bit like a hockey stick.
One of our kids stuck it in the stove coals, moving it around until it was good and hot... and branded one of his brothers with it.
