1000°c seems accurate:
Fun little science fact: Heated objects glow the same colors no matter what they are made of. It’s called Black Body Radiation. The color chart shows what temperatures correspond with various “colors” of glow.
Smells Great

Heated objects glow the same colors no matter what they are made of
True only if light emissions aren’t dominated by chemical effects or filtered by structural effects. Plenty of materials burn at different colors. Although if you wait out the chemical reactions and keep it heated, it does eventually end up with just blackbody radiation too 🤷
icelimit@lemmy.ml 1 day ago
But corrected by emissivity factor. Emissivity factor is also not constant, and changes as both a function of material and temperature. Probably associated with band gap fluctuating wrt. Temperature

Unless it is a gray body. For somewhat accurate measurements you must do math.

Aluminium doesn’t glow, even when molten though?
i_love_FFT@jlai.lu 22 hours ago
That simply means it must melt below 600°C.
A quick wiki check says it melts at 660. I guess if you’re in a really dark room, you could see the glow.

Eventually will glow human eye visible if you keep heating it past useful temperatures. 1000’C+ starts getting red hot.
Doesn’t emit light as readily as iron does, especially with iron’s oxide layer building up when heated.

Which makes iron a suitable substitute for tungsten at 3000 C

Related, but off topic.
If you ever visit Taiwan, be sure to eat the local pineapples. We have one of the sweetest pineapple and we eat the core of the pineapple. The core is actually crunchy, like the constancy of a crispy pear.

I’ve been watching Tech Ingredients search for the best shield material to test their Drone destroying extreme high power laser setup indoors for obvious reasons.
It turned out to be fruits/veggies. Nothing else came close. So he went with panels filled with thickened water.
dejected_warp_core@lemmy.world 1 day ago
That makes sense. The specific heat of water is a real bastard to overcome.
IAmNorRealTakeYourMeds@lemmy.world 1 day ago
I’m personally skeptical of laser based weapons, given that they have one wavelength. once one is developed and deployed, it will be trivial to paint drones with a reflective paint specific for that wavelength.
The results is a nation investing 100s of millions on a weapon, that once deployed will be countered by 1000s $ of spray paint.
imagine if you could get a t-shirt that could deflect a any bullet. that’s what still happen with laser based weapons.
wolframhydroxide@sh.itjust.works 1 day ago
I think that wouldn’t necessarily work once you get to the right wavelengths for it to start interacting with the organic bases of the paints. There’s only so much you can do when someone shoots an infrared laser at the resonant frequency of a C=C double bond.

The pineapple will be just fine the flesh touching the steam on the other side spread all over your body by the pineapple keeping it pressed against your skin on the other hand is going to have a nice chard bbq taste.
pivot_root@lemmy.world 1 day ago
If the steam doesn’t get you, the enzymes breaking down your proteins would surely give you horrible skin irritation.

Why was the pineapple discarded? They could have eaten it 😭

Don’t worry. It’s a black deck, so the graveyard is exactly where the pineapple wants to be.

Fake news: the underside of the ball is room temperature. Nice fucking try though.

Does it work when the skin is properly dried though? Armor would dry out over time.

Ya, it’s all a big lie brought to you by billionaire dragons. They’re just trying to get you to wrap yourself in a tasty garnish so that they get a nice citrus flavor once they are done roasting you.

My friend calls pineapples ‘Dragon Eggs’ and tossed one into a bonfire. Pulled it out later to have the most delicious roasted sweet mythical egg ever
notabot@piefed.social 1 day ago
Sounds tasty. I can vouch for lemons undergoing a similar transformation. Wrap them in foil, seal it really well, and chuck them near a fire or bbq. They come out soft, sweet, and delicious.

Tossed it in when the fire was at peak flame, and then waited for the wood to burn, the pineapple looked like a big piece of black coal

Roasted pineapple is delicious. Coat it on some brown sugar, roast it, then carve off the toasted bits. Repeat.

Isn’t the pineapple sweet enough that sugar could be omitted?
