So you took the top comment from the last time this was posted and made it your title. Fuck off @OP

they use these on the bottom of the space shuttle

This makes me uncomfortable.

Lol way to repost this and add the top comment as the title, unoriginal fuck

I'd agree if I had not seen this exact post earlier today on front page, its a like 9 hour wait repost.

Man, I’d love to lick that hot box... *guy who licks hot boxes and says it with creepy innuendos probably *
PhailRaptor
Is that in Freedom units or not?
Grimmrog
dunno, in celcius thats still pretty damn ouch.

That title joke only works in America.

Shit, from the thumbnail I thought these were some sort of metal LEGO’s.

Good thing they were in the US then, I suppose.
CustardPies
Haha he did a little test check before picking it up. Only just noticed it. I would've done like 5 or 6.
daggypants
90 degrees!! I get it !

Would still burning like fu........ Oh right Fahrenheit
sashadqaf
Such wow . Much hot .
basicwhitelich
Naw, it just burned the nerves off before he could feel it. Or he's a witch. Or both I guess.
TheWetLustyArgonianMaidRIP
These ceramics have such shitty heat transfer capabilities that they don't burn you although they're thousands of degrees.
Syldra
I'm a ceramic engineering, this is one of my favorite demos to show uni students!
Everaye
What is a demo?
GorgeFloyd
I am also a ceramic engineering!
HamboneSlammer
My schools is supposed to be great fir ceramic engineering

Q: What would happen if you slipped and grabbed/touched the sides?
unoriginalhuman
Death
Syldra
Corners are safe, edges are pretty good. Faces are hot. But the heat transfer is pretty slow, so some minor burns assuming you drop it quick
SepiaSkies
That's awesome. How predictive are the compositions w/respect to heat transfer properties? Like, oh 5ppb ytterbium, that confers insulation.
Syldra
Insulation is more dependent on structure than composition. This tile probably have many ppms of contaminant iron, sodium, calcium, etc.
HandaSeishuuu
What does ceramic engineering consist of? I am very intrigued.
Carnot
They engineer ceramics
bawfuls
Likely a specialty within material science, often under the umbrella of mechanical engineering.
SirJaeger
Material Science is under Chemical Engineering typically.
Syldra
It can be! It can also be under Mechanical or Electrical.
TheWetLustyArgonianMaidRIP
Making shit like this, that's thousands of degrees, but is so shit at transferring heat they don't burn you.
mcshady
So then how long does it take to get hot?
Syldra
Tough question, depends on what it is. This tile probably took about a day to teach that temperature

Why do you know this? You're nothing but a.. a wet.. lusty.. Argonian maid...!

2200 Celsius thermal tile
IronRod
If they're 90 degrees C then I wouldn't want to pick them up...
mrmayortheiv
How long would that have to be in the oven to get that hot if it takes so long to transfer heat?
DearLeaderIsThatCake
The space shuttle's heat protection tiles are made of this material.

Hot cakes!

DahPrincess
I fit a Rubik's cube up my butt one time. Plus I got it out without going to the hospital, so that was a bonus.

Super science-y ceramics that are heat transfer resistant.
NotaMormonbutlookslikeone
They're over 90% air so they are terrible at transferring head and super light

Well I don’t want one then

Dammit too late to add a humorous head comment
NotaMormonbutlookslikeone
Ok so it's bad at transferring heat and super light isn't a thing, I just meant it is nearly weightless
DanDangerDangerous
Like when a super hot air head bimbo gives poor head smh
ExtremeAndViolentButtFun
A strange looking buttplug.
Syldra
This one of the space shuttle tiles! It has ultra low thermal conductivity, but reasonable thermal emissivity.
atleastIwasnt36
Ohhhhhh, okay.
subparusersubber
Wat
Millsslslsls
brick that not very good at getting hot
nicebikemate
Anyone else have to say emissivity 10x before they were sure they were saying it right....?
MrGlitchyypants
it get hot but some parts dont get 2 hot
Shrike99
If one of these had a constant internal heat source such as [REDACTED] would it remain safe to handle while glowing for months? Or would it
Shrike99
get 'saturated' by the constant heat, so to speak?
DukeLetoofDune
You said a lot of sciencey words that I'm going to have to look up but thank you.
poot85
Im gonna have to take those science words as disrespek
gaenaralhonk
The most important part of understanding science is knowing where to look up what.
ICouldGoForSomePie
it looks really hot, but doesnt transfer that heat well. that is why it can be red hot but not burn the guy to bone.
MissingImage
In this case, "red hot" is a little higher than 2200°F.
awkward
Where does the energy go?
Trecares
Think infrared heater. With these, it feels very warm to be near, but "cool" to touch. Note, don't touch a infrared heater.
ocegur
The light you see, that's a way of dissipating energy instead of heat transfer. It's called emission or radiation.
