I really enjoy watching your pigment experiments.

Wow! This colour is so beautiful and a fascinating process. Using the kiln was a stroke of genius, saving time and faffing about but getting the wonderful results!

this feels like a college lecture! so informative! and what a treasure trove of knowledge this channel is! you inspired me to try making some pigments myself.

Unfortunately, I have to bring you back down to earth. You can't call it a college lecture. The video is very good, but unfortunately the chemical knowledge is lacking. First of all, what has formed there is certainly not permanganate. There are two crucial points that contradict the formation of permanganate. 1. Permanganates are crystals with a deep black color. The typical permanganate color only appears when dissolved in water. 2. Permanganates are water-soluble. What was produced here, however, is a pigment and they are supposed to form a suspension and not dissolve. In addition, the production of permanganate in a private setting is not exactly easy. It requires chlorine gas. Nurdrage made a very good video on how to produce potassium permanganate. As I said, it's a good video but no college lecture.

2:51 In fact, pure phosphoric acid is a solid, crystalline substance, not a liquid. It can also be easily concentrated to over 99%. However, it is usually sold commercially as an 85% solution in H2O. The term "glacial" is only used for acetic acid (ethanoic acid). This is because pure acetic acid has a melting point of about 16 °C and then looks like water ice. If you want to concentrate phosphoric acid using heat, you have to be very careful. Phosphoric acid is one of the few acids that can etch glass, especially when heated above a certain temperature. When using highly heated H2PO3 it is always better to use containers made of stainless steel or nickel.

hey I really enjoy your videos. They're so calming and interesting and especially satisfying when at the end the pigment gets tested.

Hey brother. It has been a year. You are the reason I started making my own paint and I wanna make sure you're doing alright. You know how on the insides of oak galls there are wasp eggs when you dissect em? I wanna make oil paint out of tons of wasp eggs from the galls because it's a side product and I've never read anyone doing it. It'll take hundreds of oak galls.

Thank you for these informative and intriguing videos. As a watercolor paint maker, they expand my ideas. Though I seek out permanent colors, I’m thinking of working with plant-based color, so keep up the variety!

I'm so glad I found your channel! It's very helpful and you're explanations are easy to follow. Thank you. It would be great if your voice audio was louder as I have to turn up the sound to hear you, then the ads tend to blast at a much higher volume which is distracting. Great vids though😊

@Prussian_Blue Жыл бұрын

thats cool bro, 4 anyone trying to do this without a kiln you can use an oil bath (beware though, because oil ignites at 300C)

You can use high temp silicone oil. DOT5 synthetic break fluid is a high temperature silicone that ironically is also colored purple!

Thank you for sharing your experience! My manganese violet attempts looked ok until I added water and then it just decomposed O.o I’ll give it another try.

@TheAlchemicalArts 2 жыл бұрын

That's what used to happen to me. You need to probably react it for longer at 230 degrees. I found that over heating to higher temps also had this problem. Another way to avoid this is to add a little excess phosphoric acid to help all the manganese dioxide convert.

@mikepolo2887 2 жыл бұрын

@@TheAlchemicalArts I definitely had phosphoric acid in excess. And the last time I tried I actually got a heat plate with temperature control, and it could do 220 (as was described in the videos/papers on the acid flux method). Do you think it may be beneficial to increase the amount of MAP? Manganese violet is such a tempting pigment!

How do you regulate the blueness or redness from the pigment, is it by particle size or ingredient's proportion or temperature ? I see thar Old Holland has two different shades of the pigment?
