Oh yeah just lick the carbon. It’s probably fine.
It is. Activated carbon is used to treat diarrhoea, you basically swallow a chunk of carbon that absorbs any moisture it comes across
Don't lick carbon nano tubes or buckyball. Also in general carbon powder can be a particulate inhalation issue.
The table is about licking specifically. It’s not a breathability table. Just so that is clear.
I assume if it's getting anywhere near your mouth you'd also be breathing it but aside from that, ingestion is also a nogo.
The ingestion/breathability table might be more restrictive. Like, elemental Sulfur is ~~perfectly fine~~no actually it’s not fine— but probably unpleasant to lick. Contact dermatitis likely but not life threatening—just one lick, ok; promise no more? ;)
Breathing elemental Sulfur is also going to result in contact dermatitis -inside the lungs. Which is going make a really bad day.
Activated carbon is also used in water treatment to remove taste/odours and many organic pollutants.
“organic pollutants” are made of carbon too
Not moisture but reactive molecules. (I mean, many forms probably do still absorb a good bit but) I forgot the exact chemistry but "activated" means chemically reactive. It binds with all sorts of reactive molecules, like toxins and many other things.
Diarrhea is also mostly carbon.
The carbon being pure is not the basis for my joke
Have you never licked a diamond before? You’re missing out.
Tastes like a campfire.
