I reckon it depends on your definition of “steam.” ?
That sounds dumb as hell, and a little “nitpicky,” but I say it because what people commonly call steam, myself included, really isn’t steam produced from boiling, but just suspended water droplets in the air. Kind of like when you take a hot shower. It “steams” up the bathroom, but I doubt you were taking a 212 F/100 C shower, unless you’re the devil himself.
Is the smoke that temp when it reaches the mouth? I doubt it, because I think that would be the same sensation as having super-hot food in your mouth, you’d probably get scalded and yank/drop the pipe right out of your mouth as a reflex.
I’ve had pipes that “steamed,” but only in the colloquial sense. Usually ones with constricted airways, and they did induce tongue irritation, but it certainly didn’t feel like 212 F/100 C. It wasn’t a temperature burn. Felt more like a chemical burn. Do other people get true temperature burns? ?
