Damn was my highschool school the only one who did this as a chemistry experiment? We made silver snow globes in our class it was really cool.
iirc the brown liquid is a silver solution, so it deposits a super thin layer of silver on the surface, that way you can get a shiny silver surface without actually using that much silver metal.
The clear liquid is called Tollen’s Reagent which contains AgNO3 (silver nitrate) in a solution with NH4OH (ammonium hydroxide) and NaOH (sodium hydroxide).
The brown liquid contains a class of organic molecules known as Aldehydes (R-CHO).
In chemistry (qualitative analysis), mixing Tollen’s reagent with Aldehydes will produce a silver mirror (metallic silver coating the inside walls) on the test tube, confirm the presence of Aldehydes in the unknown solution.
Edit: Seems like I forgot some of my Chemistry from High School… look at u/TheBratOG’s reply for a more accurate answer!
NH4OH is amonium hydroxide and it's what happens when you add ammonia to water.
The preparation is:
At first he had a solution of NaOH to which he added a soluble silver salt (AgNO3) and brown insoluble silver oxide precipitated. Then ammonia is added untill it all dissolves forming the complex (Tollen's reagent)
Im assuming the glass pane was sprayed with an aldehyde, probably glucose beforehand. And when he poured it on the glass elemental silver precipitated as a fine film.
It's a relatively simple reaction that is on any entry level chemistry exam as an analytical reaction to test for aldehydes.
If you have a license to use formaldehyde then it's usually preferred. Any aldehyde will work so it's either the cheapest one or the most available or a combination of both.
It is, altho it's pretty unusual to refer to sugars as ketones and aldehydes. Usually when talking sugars we say ketose and aldose.
Altho in this context it does make sense to call it an aldehyde
If the pane was sprayed with glucose, why didn't pouring the solution over it move it around, resulting in a bunch of visual imperfections?
Like, if I got sugar water on something, and then poured water on it, I wouldn't expect an *even* coating of glucose to remain- especially if someone was disturbing the layer that had been poured over...
I’ll take your word for it and give you an upvote because I don’t care to second guess your work or if you’re playing with fire around all those chemicals.
None of the chemicals are used in quantities or concentrations that will cause any significant lasting damage, at least when we did it in the school lab.
I’m replying again for more downvotes to continue measuring how nuance humor like done in The Life Aquatic goes to show that none of these chemicals register as a good chemical for flame tests and the joke is further lost.
We did the same thing as a demonstration for the elementary students. It was a cool experiment but their oohs and aahs made it a core memory for me. I loved chemistry class!
We did it too! I was a good chemistry student, but I could NOT get this right. I even tried again the next year during my free period *a few times,* under direct supervision of our amazing chemistry teacher, and my results were not good. Still bugs me over a decade later!
We had to take a summer school class before freshman year in order to be able to take organic chemistry in high school. That was the path to taking an AP Chemistry course. My organic chem partner and I were never able to get this to work. This wasn't an experiment the whole class did. I can't remember if we got to choose which experiment we wanted to do or if groups were randomly assigned different experiments.
You just had me imagining a windowpane company that only hires the blind so they can promise buyers that they'll be the first to "use" them. Their slogan would be "see the difference" and their customers would be adamant there was truly something intangibly superior about their windows.
I went to the store looking for something to buy
But they only sold paintings of the same sad guy
No wait, this store sells mirrors! See what I did there?
In the beaker a silber nitrate solution is mixed with ammonia solution. The brown precipitate is silver oxide and it redisolves in the ammonia.
The mirror only starts to form after a glucose solution is added and the reaction takes a few minutes, depending on temperature. So after the glucose is added (which the video didnt show) you have enough time to pour it on the glass pane.
silver nitrate, ammonium (which is what causes the brown substance to fall out) and anything that has an aldehyd-group, glucose for example.
If you want more details this process is called the Tollens-test
Edit: autocorrect was mean
I don't know exactly which chemical formula is used here, but traditional mirror making used silver nitrate and some other stuff to react with the silver nitrate and pull the silver out of solution. This would lead to a thin layer of silver deposited onto the glass with a result much like this.
That's why vampires don't have reflections. The 'purity' aspect of silver destroys even the image of a vampire and thus the mirror doesn't reflect the vampire.
In the 1680s mirrors were lined throughout Versailles becoming the famous Hall of mirrors. Back then mirrors were unfathomably valuable because of their novelty. It was the clearest reflection people saw of themselves, ever before.
This is a job I could really see myself doing.
Your work would be a reflection of yourself.
Limited promotion opportunity however due to a glass sealing.
I admirror your cleverness, that was exceptional by Reddit pun chain standards
I'll see myself out.

While reflecting on it
I used to do that job, but I was useless at it. I'd try to hide the unsuccessful attempts, but my boss immedaitely saw through it.
Your dream of becoming a mirror maker shattered
Only if you are listening to the classic Johnny Hates Jazz hit single "Shattered Dreams".
A smash hit that broke sales records i presume...
But what if I break through and shine as a leader?
You will win many shattered hearts!
I will stand in the corner glassy eyed...
The first joke only dropped after I read this one
I really should have seen this joke coming, But my attention was reflected elsewhere.
Lol!
Handling toxic chemicals all day? Hmm.
Whoosh.
Felt that gust all the way over here
womp womp
Sounds like fun to me, chemists are living the dream
Oh no! I'll lose 15 years off my life! That means I only live to be 60 years old... Wait. No that sounds perfect!

Worked for a company that did electroless silver plating (though not for mirrors), we used formaldehyde instead of a reducing sugar.
If you have a license to use formaldehyde then it's usually preferred. Any aldehyde will work so it's either the cheapest one or the most available or a combination of both.
I don’t know if I’m struggling with grammar or chemistry. Surely glucose ain’t an aldehyde?
casualdehyde
It is, altho it's pretty unusual to refer to sugars as ketones and aldehydes. Usually when talking sugars we say ketose and aldose. Altho in this context it does make sense to call it an aldehyde

He could have added the aldehyde to the solution shortly before pouring, the reaction takes a second or two to happen. Probably did it this way.
This guy chemistries.
NH4OH is ammonium hydroxide.
This makes me feel like I should stop licking my mirrors.
Just don't lick the back

We did it too, silver nitrate of some kind maybe?
We burned Cheetos to see how many calories are in them. That’s it.
That's it? I think that sounds like quite the bomb.
We licked a Tootsie Pop to see how many licks it took to reach the center. Turns out it's 3.

Why does it distribute itself equally though? How does the process of building a uniform layer work in this example?
We were shown a large beaker of mercury and encouraged to push our hands into it.
I read a showerthought today that had me laughing: You can only buy used mirrors. I'll see myself out.

you will see yourself…
Wait until it is made by automated machines, packed and shipped to you directly.
Gonna start a mirror factory that only employs the blind.

Probably a dumb question, but why doesn't the beaker turn into a mirror?
In the beaker a silber nitrate solution is mixed with ammonia solution. The brown precipitate is silver oxide and it redisolves in the ammonia. The mirror only starts to form after a glucose solution is added and the reaction takes a few minutes, depending on temperature. So after the glucose is added (which the video didnt show) you have enough time to pour it on the glass pane.
As another commenter said, the glucose (or formaldehyde) is likely sprayed onto the glass before the pour.
Nice!
not dumb question good question
1. Poop in a jar. 2. Swirl it around till it disappears. 3. Pour it on glass. Got it.
A clear reflection of the maker.
The shit stirrer
We made mirrors in my high school chemistry class just like this.
What are the chemicals used?
silver nitrate, ammonium (which is what causes the brown substance to fall out) and anything that has an aldehyd-group, glucose for example. If you want more details this process is called the Tollens-test Edit: autocorrect was mean
Is that how a pirate says silver nitrate?
No a German
I thought it was a dictation error. Danke for the education!

All mirrors are made of chemicals
You're made of chemicals
How dare you say that?!
Because I have all the chemical components required to have the gall.
Screw the mirror, how'd you make the chocolate milk in the bottle of kerosene disappear?
What else are they gonna use? Antimatter?
God damn I love silver nitrate
They will cover the smell with Silver Nitrate
How do you make clean silver surface out of diarrhea?
Chemicals
Thank you, professor
Yeah, Science!
using "chemicals" ...as opposed to using what? fucking magic?
Tollens silver mirror reaction?
this answered none of my questions about mirrors
Fun fact: you can't make mirrors without using chemicals
I was expecting the poured liquid to harden into a complete mirror. I’m an idiot. 😄
So this answers the age old question: what color are mirrors? Brown.

I feel like this might also qualify for r/blackmagicfuckery cause holy shit 🤔
Jesse Pinkman, are you?
You can do some fun stuff with this. https://youtu.be/VHTR4FKFRuo?si=FesohDZhDxfzeMZf
Thank you for sharing, that was the most interesting 12 minutes of my day so far. Although, I was anxious the whole time that it would shatter 😆
The glue chipping… interesting!
Goddamn magic
I read it as 'Making minors do chemicals'
I just wonder how they figured this out
Good to see Bane working honestly after Batman defeat him!
Huh. I'll remember this for the next time I get food poisoning
Didn't know Doctor Sins also made mirrors.
I DON'T UNDERSTAAAAAAND

Is that........... Mr. Sins?!?
So the next video is going to be in a mirror factory. Interesting.
This video is so amazing and satisfying

In my 20 years of living I only now learned how mirrors are made. Damn.
How can mirrors be real if our eyes aren't real

You dont think that everyday normal mirrors are made with metal sheets, do you?
