Don't know where you got those numbers, but I could comfortably hold a 65 deg C flask in my hand for many minutes, and 160 deg F is 71 deg C. 75 deg C got uncomfortable but I could hold it for a few seconds....3rd degree burns? Lulz.

I am going to wager a guess that the flask was made of metal right? Energy transfer from metal is much lower than that of water. Hot water is more dangerous than hot metal.

Nope, it was glass, which might have something to do with it.

Edit: Wiki calls BS on your claim, where aluminum has a thermal conductivity of 220 W /m K, where water is .5-.6 Borosilicate Glass (or what I presume is glass that's 96% Si) is 1.2, or twice as conductive as water.

Edit Edit: If you're talking about heat capacity, then yes water is more dangerous, as it has about three times the heat capacity of glass or aluminum.

That is what I meant, yes. Hot water is a lot more dangerous than glass or metal.

if any of this stuff is true, that is blatant and obvious cruel and unusual punishment.

Thermal conductivity doesn't mean much if the material has very low heat capacity. The classic example is a white-hot sewing needle vs an orange-hot rebar.
