- Today I'll be making Prussian Blue, which was the first modern synthetic pigment. For this video, I'll be isolating it and using it to make paint, but in the future, I''ll be diving into the whole process of cyanotyping.

next do egyptian blue!...
You can make it with your fecies
it’s fascinating to see him have all the patience and time to make prussian blue and little to no patience to paint with it 😂✌🏻
confidence difference 😂
Shall I keep this at 666 likes
No
_No I am not_
Also yes I wish I had his patience lmao
Different interests

7:05 "until it turned to a greenish-blue" ... also known as cyan! Cyanide gets its name from this exact color because it's in Prussian blue, and I find that very interesting. Most people would think the color and the compound are unrelated, but instead they are entwined
O M G!! thank you for this!!

You should go bob ross mode and make some of that Titanium White... Phthalo Blue... Alizarin Crimson .... Sap Green ... Cadmium Yellow Hue
He'd have to be careful with the cadmium yellow; cadmium is super toxic.
@@lanadoesathing maybe some yellow ochre, then
@@lanadoesathing cadmium yellow hue, the word hue indicates that it isn't the real stuff. Besides that, cadmium isn't as bad as people make it out. The rate of skin to blood is super slow. It's much worse if it's eaten.

Nothing has ever made me feel as understood as this video. A professional chemist, that consistently makes 30+ minute long videos that contain crazy difficult and dangerous processes using chemistry, quits painting a butterfly because it got to difficulty and detailed. Thank you for this.
Just shows that everyones strengths lie at different areas. No one is perfect and its nice seeing that from time to time.
Hi Nile, I found this very interesting. I've been using Prussian blue more than fifty years, as a machinist and tool maker, using it to spot metal to scrape to fit, and match the fit of pieces. It makes a very fine film, and one can easily secure fitment to tenths of a thousandth. I've bought two tubes of it in fifty years, the last was a decade ago, as oil paint, it gets crusty, but remains the film forming, crust knocked away. Thanks for doing this, I never have to worry about running out again.
It's such a shame that your comment didn't receive any likes.
@@marvinzwettler8171 he has 8 now, finally
My great-grandfather was the first to synthesize Prussian blue in America. He was a German chemist who emigrated. He did it in his San Francisco apartment kitchen in the early 1920s.

The picture of a face at 11:15 is a precious moment. Your strong reaction to it reveals that art is deeply important to you. I remember my reaction to my first drawings when I took a drawing class at age 30. It was a very negative reaction, but after about 100 drawings I began to improve and made drawings that were often pleasing to look at. Your painting shows a natural talent for getting the paint on the paper and making a balanced and confident design. Art could be a helpful tool to communicate ideas about chemistry.
C:
Like an art teacher once said: "you have a hundred bad drawings in you that need to get out, before you get to the good drawings"
From left to right:
1. Row: Potassium ferrocyanide, Indole, acetylsalicylic acid (aspirin)
2. Row: o-cresol, Nile red, Caffeine
3. Row: Salicylic acid, Nile blue
That is not indole it is skatole
The second one on the first row is skatole; the first on the second row is 2-isopropyl-5-methylpheno (thymol); and the first on the third row is methyl salicylate (oil of wintergreen).
Wait so you're telling me that the names of both of his channels were actually real chemicals all along?
I like watching non/beginning artists pushibg themselves, like you did with the butterfly :) good job man!
Bruh I'm an artist and I couldn't do that butterfly..

"it looked like something a two-year old would make."
We all start somewhere Nile.
imagine if you're a scientist and an artist at the same time you just make your own colors when you need them
That’s genius :^
There are some that exist, in fact many.
Da Vinci was one of them
Shitloads of painters DO do that.
But they specifically buy the already made pigments and just make their own paint medium with it, bc there is already a shitload of pigments available.
Granted, there are a few that are pretty expensive bc of rarity but actually creating your own of those pigments might not be practical financially.
Imagine you are Leonardo de vinchi. That's who you are describing after all.
How ironic, Prussian blue on Nile Red's channel
It is IRONic indeed
Andris Kovacs uh, nice one!
Jack Hudler yep, on an old video
Its a red dye. He drew the structure during this video on the first sheet.
Marky It’s abandoned, though.
Such a happy little color. Can you do Titanium Hwite next?
BobTerje Bob Ross is that you?
He should start a series in which he makes a many different kinds of pigments.
Isn't this a very toxic pigment?
I am talking about the titanium white.
Gustavo Fernandes we all die at some point
My grandmothers(RIP) favorite paint color. She once gifted me a really nice set of oil paints from years before my time. it had this color in it.
You went form doing chemistry to genuinely trying to make a painting for the first time in your life. You are so cute. Also the butterfly was so nicely sketched 🌸
"just for fun you shouild try to guess these molecules in the comments"... I'm a sophomore in high school what are you expecting from me *cries*
h2o is coming out of bob’s eyes
Freshman in college. Just means I can cry harder.
I'm almost about to graduate with a chemistry degree and I still blanked out 😭
@@roshnigupta9914 I'm in my last year in highschool and I figured it out. Just go check through the comments, I posted it there somewhere. As for strategies to figure it out, I mostly just tried to name the molecules and typed that into my search engine. As for the two huge molecules I just counted the number of atoms and surfed on the internet to find what their names were. It's impossible to look at the molecules and just know what they are, even if you are a graduate in chemistry. It takes some time, patience and persistence. I was literally just bored and I would also have given up, to be honest, but I needed something to do.
10:55 1)hexacyanoferrate (II or III) 2)skatole 3)aspirin 4)menthol 5)nile red 6)caffine 7)methyl salicytate 8) 9-diethyloamino-5H-benziphenoxazin-5-iminium

You should teach nomenclature
Thanks I was looking for this

18th century synthetic pigment made of cyanide to slow down the effects.
That's sounds so cool lmao
As a painter, watching this was especailly entertaining. I love this kind of shit, the interlap between art and science is what I live for.
Whenever you are making ferric chloride, I recommend making sure the steel wool is oxidized... The rustier the better. It will dissolve mor readily into the acid, and most of the time the carbon will have leached out and bonded with oxygen (the oxidation of steel tends to create carbon dioxide as a minor byproduct.) This will render a cleaner result.
Soak the steele wool in hydogen peroxide (store bought works just fine).
@A. Meowzki Build an hho generator using salt water, an strong power supply (dc is preferred by me) and steel wool
@Subhash Kommalapati well in the next step he oxidized the ferrous chloride with peroxide anyway so this is just mixing the 2 steps together to get a better result
You could just set it on fire, no? The stuff is flammable, and cheap.
as an artist I love seeing your scientific approach. It's literally the opposite of my own thinking and its refreshing to see other ways of thinking to get out of my own head. I also think it's funny how you called yourself lazy a few times but sir you're literally making a dye and other chemicals. That's pretty cool. Good job :)
Serious props for posting your art. Even when you're a seasoned artist, it takes a lot of courage. Also, I didn't know oil paint was that simply made - you know, after you've gone to the trouble of synthesizing the pigment lol.
Hi. Medical lab scientist here! We also use Prussian blue as a stain for bone marrow slides to evaluate iron storage. I didn’t realize it had so many other uses too! Thanks for this 😁
I wouldn't want to use your kitchen for food, god knows what's in your oven and coffee grinder by now ;'D
GiggitySam Entz Don't worry, it's the lab 'kitchen'.😉
GiggitySam Entz yes I was wondering about his coffee grinder
Read this at the coffee grinder part
First thing I learned in chemistry was never to use lab containers / instruments for food storage or consumption. Same goes with potable water .
11:44 You just learned the first lesson that everyone painting tabletop minis learns: THIN YOUR PAINTS ! Great video.
I followed this same method to make my own Prussian Blue today, which is something I've been waiting a year to do.
Haven't been able to dry it out yet, but it's been an awesome project to work on, and very rewarding. It's not until you see it in person that you realise how fantastic the colour is too, pictures and videos really don't do it justice
All I can hear is Bob Ross whispering “Prussian Blue” into my ear.

Bob ross's techniques require a specific wet coating on the canvas so you can work with the paint more on the canvas.

Oh damm thats where I live
BABAHA
HAHAHHAA
IM A NERD BECAUSE I GET IT BUT I LOVE THAT
Please please please do a Bob Ross imitation.
Chopersky lord knows it would be the first time
I work with pigment chemistry all the time, but never got to actually synthesize most of them. I am very impressed on how well it turned out! I’m looking forward for what is next.
I absolutely adore your content, i think i've watched everything you have, I love the experiments you do with DCM.
More synthetic colors would be neat!
Maybe mauveine, from a quinine rich source, like tonic water?
I would say using the gesso is a must. Otherwise the oil would seep in to the absorbant paper and over time deteorate it quickly in addition to decreasing the amount of binder in the paint which would also be a problem.
When applying the gesso try going in just one direction across the entire paper during the application of one layer. (As the paper is oriented on the screen: try going in a cross direction = left to right and next layer top to bottom) You don't need to have perfect coverage of the paper on your first layer - build it up over time ( specially with thinner paper(100g/m^2) try to not go over the same spot over too many times (in one layer). I noticed the gesso and the paint seemed quite thick try thinning the gesso down with water and the paint with turpentine.
Paper warping - the paper does worp when wet thou then stretches again when fully dry. (With some papers it's a problem even after drying they stay worped, but with an aquarelle paper at 300g/m^2 I would expect it to stretch just fine .) Perhaps try a very diluted coating of animal glue abbout 2-3dkg for 1l of water to pre strech it before applying the gesso. (Also why not use a brush to apply the gesso?)
Good effort, I enjoy your videos a lot.
Omg so much information in one video , lovedddd the process , you have a ton of patience .👏👏
I'm an aspiring artist and I learned a lot from your art tutorial. This will be the quality I aspire to achieve in the future.

god i just left the fandom-
prussian blue is one of my favourite colors, this is so cool! thank you for the video!
Prussian blue is also often used to check surface topology and relative flatness. A flat reference like a granite surface plate gets a very thin layer of blue applied and the part to be checked is placed on topped moved around slightly. This transfers some of the blue to only the high spots of the part, letting you see the topology!
thanks algorithm, it's unexpectedly fascinating
Please make a video on toxic waste disposal/neutralization of dangerous compounds e.g. manganese heptoxide
just reduce it and save it up in a container with other heavy metal salts.
Ive worked often enough with it... Thats why I said REDUCE it!
🎮 ms_swag 🎮 you already got the answer. Whatever in acidic conditions will be oxidized by it. The good use for it is making chlorine or bromine ;)
My bad ;')
dumping it in water tuns manganese heptoxide, the anhydride of permanganic acid, back into permanganic acid, which quickly degrades back to water, oxygen, and an unreactive manganese ore. the only danger in it is bringing it into contact with anything it can oxidize
Hearing you describe painting with the same analysis as you doing chemistry is hilarious
Second approach to paint on the pallet was great. Youd find a less saturated brush doesnt just smear. Not everyone is an artist so thank you for humbling yourself and making an effort.
I think the drops looked like condoms.. xD However man, this is a very well done video!! Thanks.. i'm looking forward to the Cyano-printing process!! Keep up the good work..

Micropacker?
Yes! My husband and I have been waiting for you to do this video. We love your channel!
Im glad you liked it!
NileRed thank you! Keep up the fantastic work!
Holly You piqued my curiosity. Do you have plans for using the pigment? I am going to see whether I can use it in making coloured glass for glassblowing.
Flavourless Josephus that sounds awesome, you should record your progress on video and upload it to UA-cam. I don’t have any plans for the dye itself (I just love the history of its use), but now that I think of it - dying some yarn would be nice, a dark blue crochet scarf or table runner would be beautiful. My husband does have plans to install a kiln in our garage, I’ll tell him about using pb for glass blowing. Tc!
Flavourless Josephus No, you definitely can't use Prussian blue for making colored glass. The dye will disintegrate WAY below the softening temperature of even ordinary soda-lime glass. It's no coincidence that almost all the pigments used in glassmaking are various metal oxides (which are pretty much the only compounds stable enough to withstand the high temperatures required).
The whole point of adding liquid white or gesso is to make your oil paints slide around a bit more easily and make the painting look sharper and help with blending because it helps to make the surface of the canvas smoother, taking away some of the friction. So you don't want to let it dry, and it won't be very helpful if you use watercolor paper instead of canvas. At least that's what my painter friend told me when I showed her this video.
I would love an art series of more different pigments! Would be lovely :)
I love you and your channel so much. I flunked highschool Chem but just watching you paint so methodically made me smile so much, your narration is so funny, I love that you love what you do. As an art person I can't tell you much much joy it brings me to see you paint chemicals with a thing you made yourself. It simply cannot be more left brain... but you are an artist by creating these videos, thank you for this.
You followed a step by step guide to draw a butterfly. God i love you.
Oil paint usually should be mulled a little longer because the longer you mull the paint the more pigmented and smooth it gets. This is making sure all of the powder is completely mixed and saturated with oil
This is epic stuff!! As an artist I'm curious as to how pigments are made and this video has given me a lot of insight into how a paint that I used is made. Please give us more!
For oil painting - Bob Ross. For acrylic painting - ColorByFelix.
#0 brush for detail and fine lines
#5 is good for general drawing and filling
Use thicker paints for your base and thin it out if you want to paint over that with another color or dilute with turpentine and white to lighten the shade a bit.
I know... The video is old but it's never too late to try something new :)
He sure does like saying “in theory” 😂
In theory, he does.
Prussian blue is the best for uniforms
I actually think all of your paintings are very charming. I’m extremely fond of the chemical structures one!
I love seeing the art stuff in a hard science setting. Also the patience to use oil paints? i got that. The patience to make oil paint, no less homemade dye? Could never
ferrocyanide/iron(vi)cyanide, caffeine, salicylic acid, menthol, nile blue, and aspirin
I just recognized caffeine, i'm lame
When you opened the lid of the coffee grinder, the powder that flew was amazing!!!
I love you man! Your videos help me so much with my homework!
Hi I’m a painter and this is my favorite blue by far- so interesting to watch this
amaaazing video. Although I'm a derp and always failing at my chemistry test, this video is really entertaining! And the way you draw is just adorable
Good video keep up the good work you are one of the best science channels on UA-cam!
sciencechemistry One of the bests?!?! He is the best. :)
what is the use for hydrobromic acid
Wow. The goop at the end looks like satisfying scraping. I’m aware of how laborious making pigment can be by hand, so much dissolving, milling etc. This was indeed also a lot of steps. I love watercolour and prussian is a lovely blue. You do want to add tiny amounts of oil as you mix and also paint in thin layers at first, but I particularly like your butterfly.
Hey dude! as an artist, I would never diss your skill because I'm in awe of your chemistry knowledge and that is something I don't posses. Also good on you for really trying with the art anyways, I thought it made for a fun watch!
Bob would be proud
It's easy to make K4Fe(CN)6 (pottasium ferrocyanide) by reducing K3Fe(CN)6 (pottasium ferricyanide) with KOH and H202 (diluted).
The Yield takes a hit though. But a good method that can be accomplished within an couple hours. Be careful with amount to much H202 can cause excessive heat generation.
Troy Selby-Karney for my experiment I used 3% H2O2, so there was no way for excess heat to come, and the yeald was remarcably good
Cool. I've only done it a few times so 3% H2O2 is a good catalyst cool. Used 10% and it caused a few heat issues for the first few drop additions. That's was nice to know.
DUDE>>>>>
You made that paint.
Not just mixing it but YOU MADE THE COLOUR from scratch like i would a cake.
It is beautiful:)
I love that you're patient and skill full enough to make pigment but drawing a butterfly is where we draw the line
One potentially interesting pathway for the potassium ferrocyanide, though I don't know if you can get much of a yield, might be to synthesize it from the cyanogenic glycosides in the toxic parts of plants. Many plants produce compounds which are enzymatically catalyzed into hydrogen cyanide as a defense mechanism. Bitter almonds and apricot pits are probably one of the more available sources for this and seem to be available for bulk purchase online. By grinding those seeds and soaking their powder/pulp in water you should be able to make a cyanic acid solution.
From there you could synthesize it from an alkaline aqueous solution of ferrous salts in a single step. Given your goals and what's readily available I'd suggest potassium carbonate, which can be attained from brewing supply stores or directly from a chemical supplier, and ferrous sulfide which you'll probably just have to order. Hydrogen cyanide should react to form potassium ferrocyanide, hydrogen sulfide, and CO2.
Alternatively there's a more well tested and easier to purify method based on how they do it in commercial production. By reacting the cyanic acid with calcium hydroxide (slaked lime) you'll form pretty straight forward calcium cyanide solution. From there heat it with ferrous sulfate(Iron supplement) to produce calcium ferrocyanide. This is obviously a step that necessitates a good fume hood. By adding potassium chloride (low sodium salt) you'll produce a nearly insoluble double salt of potassium calcium ferrocyanide which will fall out of solution. Filter and clean it with water. From there you just need to react it with a potassium carbonate solution. Insoluble calcium carbonate will fall out of solution and you'll be left with a crude potassium ferrocyanide solution. The product can be crystallized out as the trihydrate and purified further from there.
commenting for me
Prussian blue had always always been my favorite color, it was really interesting seeing how it was made.
I love William Osmans new content
