Favorite part of the week... when all the chem tubers release their weirdness on the world.

Good job! A couple of comments: - your MnO2 is heavily contaminated with iron (hence the yellowness here and there). To get rid of it, you set your pee-like solution's pH to ~6 IIRC, and start blowing air through it (aquarium pupm is enough). At this pH iron oxidizes to 3+ and precipitates as a hydroxide, the rest stays in solution. To colour shifts from yellow to faint pink, with an orange/brown susension. - the lumps created in a ball mill were due to moisture still present in your pigment. You should have ground it with a mortar, put the coarse powder back again to the oven, dry it properly, and then use ball mill.

I nearly chocked on my food from laughing when you turned on the vacume pump, whilst talking about how much it's been through, and a bunch of powder just shot out of it lmao... too funny.

As an alternative to an acrylic binder, I hear that tempera can be easily made from egg yolk (and a few other ingredients), it being the predominant medium of choice until the Early Renaissance period.

Quality is increasing dramatically epic

Try milling the pigment with an acid functional resin (the acrylic is a good one) dissolved in solvent! it will produce a very fine dispersion that will be 100x better than just mixing them ( source; used to work as inks and coatings chemist).

For isolation MnO2 from battery paste you can: 1. Wash paste with water and filter it (as you did) 2. Add MnO2/C mixture to H2SO4 solution and then added H2O2 to dissolve MnO2 3. Filter solution from carbon 4. Precipitate Mn(OH)2 using NaOH 5. Add H2O2 to oxidize Mn(OH)2 to MnO2

I learned the same lesson, to use a plastic spatula instead of my beloved stainless steel spatula when harvesting manganese dioxide from carbon-zinc batteries. I loved that spatula. 😢

For a new spatula 😅

Love the Floating Sieve :) I hold my mini-vortex paint mixer to my version of your separator, I cannot express how satisfying it is to see the gravity filter work that fast.

I always appreciate seeing these green[power], good for the environment projects! Returning batteries to their native habitat, all while making an interesting pigment? Excellent work.

A wonderfully shown process !!!

I love this color! I find it fascinating that this is the only other manganese compound that has a pretty purple besides potassium permanganate. However, the mineral rhodochrosite is made of magnesium carbonate and has a stunning magenta pinkish color. You should make a color chemistry series.

Mam nadzieję że w wakacje będzie więcej takich fajnych filmików.

KHSO5 can be bought in every hardware store as an oxygen treatment for swimming pools. Sometimes it's also called "pool shocker".

From a non-science guy I love watching this sort of content, I particularly like your style, keep up the good work!

You can also precipitate Mn(OH)2 using Naoh then filtering it and leaving it to dry in air, the Mn(OH)2 will convert into Mno2 in air. This method is much safer than producing a ton of chlorine and the final product is also more pure.

it looks like nilered's purple gold towards the end. I wonder if it would do anything at all in an alloy

@Amateur Chemistry Another thing to watch out for, is the fact that some zinc-carbon batteries can also have ammonium chloride as the electrolyte. Not just that the manganese dioxide may also be contaminated with iron.

Great idea 👍 Beautiful picture 😍

Awesome video, I have never seen this done before!

I think Piranha solution would turn all the carbon into CO2, but might be expensive.

It always amazes me how seemingly easy it is to make molecular chlorine. Such a reactive chemical and you can get it just by mixing stuff together or putting electricity in salt water.

Not only do you have a very pleasant way of presenting something, you also know how to incorporate extremely funny and amusing moments into your videos. In short, great video as usual. 👍

Watching u since u started love ur content lel best dinner content I have found ....❤❤

Lesgoo i have been waiting

absolutely epic

5:30 AC: "There doesn't seem to exist any simple trick to make to make all this go faster" Centrifuge: _EXISTS_

This video was brought to you by ... DOO da da doo doo do da dooo .....

I love your style of video so much! They always make me happy. That painting at the end is INCREDIBLE! I bet it's so satisfying to see all your work on this end up with a piece of art you can look at every day. :)

Your friend made a gorgeous art piece!

Just a small note, I haven't watched the whole thing but heating the MnO2 suspension in the microwave oven somehow makes the particles stick together and making decantation/filtration extremely easy

Looks like you got a turning table to up the game! Great video👍

You can also produce MnSO4 from MnO2 by reacting with gaseous SO2

Shoutout to the Action! Never a true kludge without some of their stuff haha:') Enjoyed the video, thanks!

Ultrasonic cleaners are great for mixing and also separating stuff from paper such as from the tape

17:33 polish phosphoric acid lol

7:07 - guuut nektarine :)))))

Y don't you get büchner funnel? they are great for stuff, that fucks up glass frits. Also they are relatively cheap, and IMO even better than glass frits, because you can just dump the content without painful scraping, so you get less losses.

Perfect as usual

for the Vacuum you nee a recirculating venturi pump where there is no metal body to be eaten, you can get glass ones and use a magnetic water pump if desired. For the diammonium phosphate its DAP aka homebrewing nutrient for beer and cider.

You may have gotten a strangely high yield because of trace metals in the battery that are catalyzing the reaction

Also, you can maybe try to heat the mamganese dioxide and carbon paste to 500-600°C to oxidise carbon to carbon dioxide. Although the manganese dioxide might also convert to manganese iii oxide... but I guess, it's worth a try!

Having made this reaction myself for a uni project, I respect all the steps you went though to clean the manganese and pyrifying it by dissolving it with acid. I went by the road of pyrolysing the carbon away. It did sinter the manganese and I spent almost a day to crushing it up finely again. For phosphoric acid a lab mate help extracted some from Coca-Cola as a proof of concept that this pigment could be made from house hold items, the ammonia we got from cleaning chemicals. In the final reaction I used some more acid from the lab store room so we could end up with enough to actually paint with. Mine did ende up more dark purple, possibly due to mixed oxidation states of the pyrolized manganese according to my teacher at the time. We made about 100 gram that was split 3 ways between the lab mate, me and for professor lab collection.

U got a new handle for U mortor and pestle 🎉

i nominate you to the top10 of youtube chemist accents chemforce and thoisoi are naturally on there as well. if you want to crush up some rock like material you can take a glass bottle with concave bottom, press it down on the target while moving the top of the bottle in a circular motion, this confuses the compound and it turns into a powder always crush it up a bit before trying to dry it out anyhow

Babe wake up, NileRed poste- umm... Oh wait.. Babe wake up, quick, amateur chemistry posted!

What's wrong with burning off all the carbon as the first step?

Amateur Chemistry : The MnO2 paste is so messy and sticks almost to everything and cleaning it is a huge disaster at the mean time (5:11) wearing light gray hoodie and handling the MnO2 paste with additional splashes 😂😂😂

Could you have done this with battery stuff + HCl -> MnCl2, +NaOH -> Mn(OH)2, + (NH4)H2PO4 + H3PO4 -> NH4MnP2O7 ? I'm not sure about that last step, if Mn(OH)2 would work. It feels like just more water would be liberated but I don't know.

Chem tubers are the only reason i enjoy chemistry now. Keep on keeping on

Can you make a short about copper glutamate complex? It has a beautiful blue color! Our professor showed us a demonstration where he mixed a solution of basic copper carbonate and a solution of monosodium glutamate and it turned this deep beautiful blue!

10:52 my favorite unit of measurement is: metric frickton

Wonderful work here! I wonder how the color and texture would be different if you made the pigment using tetraethylammonium dihydrophosphate instead of the plain ammonium salt :0

Greetings from Germany, nice video!

Thanks for the upload, sir.

I wonder if you can just heat it up and burn off the carbon

Looks like a beautiful paint. I wonder how stable it is or if it will change colour over time.

I like your sense of humour.

Third?

Would adding the battery paste to piranha solution be a way of eliminating the carbon whilst generating manganese sulphate?

Pink? Batteries? Must be manganese-based.

this is... amazing? why tho

17:33 kwas fosforowy 18:00 olej kielecki 4:55 hating on EU I can only guess where are you really from... only guess...

great video your the new nile red

Hehe, very nice channel 😅👍 I'm used to make acrylic and watercolour paint from pigments and I even made some prussian blue by myself but I never had the idea to try to make manganese pigments but now I'm really hyped for it 😂 ❤

What about creating ferrite cores for transformers from the parts of alcaline/saline batteries?

Why not eliminate the carbon in step 1 with piranha solution?

Incredible video

"Some kind of warfare coca-cola" 😂

My experience with this is that the pigment reaction seems to be pretty sensitive to temperature, I had one result much like yours, and the next one using a slightly lower temp resulted in a much deeper color.

So.... Paris Green when?

I expect all my Coca Cola to be war Coca Cola from now on

I wanna see you do a painting on video!

Piranha to remove the carbon?

Question: Couldn´t you have used a high temperature furnace to get rid of all the unwanted oily solutions and carbon particles added to the mangenese dioxide and then later purify it more easily ?

14:29 the warfare cocacola is actually healthier than the real cocacola

I thought lead paint was white

Chemistry is cool

First like and first comment, love you man

The old thumbnail was better retun it

Thanks!

Nice

Instant subscribe.

Can you please share the schematics of the ball mill, please?

Patatas Fritas si

18:00 ah tak. Dobrze widzę? Olej kujawski ?

21 mins in, Tyranid blood

Why not make some good old toxic lead or cadmium paint from lead acid batteries or nicd batteries? It's not like you have to eat it

nice

9th 😂

@7:52 Black is sus

dlaczego tak przedłużasz końcówki 😂
