Terra Ignis: Burnt Ochre Pigments
HTML-код
- Опубликовано: 25 авг 2019
- This week I take some of the ochre that I have been collecting and Calcine it in the fire. The Calcination / Burning of the Ochre yields some beautiful chocolate brown colours.
🎨 Ever thought about making your own paints? 🎨

I agree with what you say about making interesting blacks by adding blue to brown. Works really well in tempera.
I will have to try that, tempera is the one area where I tend to use pure blacks rather than mixing them.
That weird purply pigment looks like a fun challenge, and the red-gold of the pigment above it is a little slice of sunset.
Australian Ochres can be so unique and beautiful I hope I can get out into the bush and show every one some of the natural Ochre out in the world.
Thanks for your Big effort. 💪🏻✨👏🏻
What a beautiful channel! I just discovered it. Thanks a lot for sharing!
Hello! Thanks for the videos, for think oil pigments more interesting, my friend, thank you for this great generalization! Good luck!
This made me hungry. Even started craving some Milo. Also would love to see more watercolour stuff!
Meat grinders from op shops- Syrian rue pigments are interesting too.
this is brilliant!!!
Love it big thank you

i find that the granular that is left can be just wiped off when the watercolour has dried . it doesnt soak into the paper
I Picked up a few yellow color shells. After processing it to pigment, I mixed it with purified Lindseed oil. It wasn't as saturated as P42 yellow ochre ofcource but i was quite close, more like a Raw Siena. But after it dried for a while it turned into a neutral green color. I made two samples. One with purified lindseed and one with stand oil. And the color changed in both of the samples and only when it dries. It yellow when I paint, but dries very neutral greenish. Might you know why this has happened? The ochre shell is like mud sediments that has harder with time, but it gives off like chalk. Very powdery.
Love your video so much. I did heat a sample of mars black, just commercial product, and I believe it turned into a deep and neutralized purple-black. Hope you could explain more about chemical aspect of calcination as well as your pretty experiments.
Thank you I am very glad you enjoy them, I am working towards doing some more in-depth stuff but as I have no training as a chemist I don't won't to give out wrong information. I am constantly reading and learning and I will share what I learn and I was planning a future video on calcination and other chemical / Alchemical operations.

Enjoyed the video! Where I live I have yellow ochre and the red version. Just had to get the roots and little rocks out of it but afterwards made a great oil paint. I make my oil paints a soft butter consistency like Bob Ross does so you can do his wet on wet technique.
I've been curious about making a oil paint that uses fine metal powder. I'd love to see what a golden brass would do mixed in the oil. If you tried to make this in the shop I guess the only thing to do would be to grind (I mean manual not electric) it and go through it with a magnet to get the iron shavings that will come off the grinder. After that you should have clean brass, bronze shavings
@@twycross3 there are ways to make a metallic pigments the old methods are complicated and use tin and Mercury and I haven't looked into the modern ways yet. As far as I know only gold and silver can be used as straight metal pigments but I will do more research in the future.
Please make video on cobalt blue and cobalt blue deep.
Thanks for making this video.
I just have a question, Is the use of iron necessary here in color change? Or is it the same case if stainless steel pan is used?
The iron has no effect on the colour its just cheap to use, but if you are happy to sacrifice a stainless steel pan to the flames then it should work fine.

I used heating it on foil using a fire gun, but I recently thought I'd try heating it on an electric stove and pan, not sure if it's a good idea though... Thanks!
Have you tried a water ball mill? I've been thinking on renting one in my city so I can have very fine pigments
I am currently looking into building one hopefully in the near future.
Wanna know if u could make the Mayan blue. The one with paligorskita.
Not sure yet it's on my list to research.
مرحبا كيف حالك فيديو جميلة ومفيدة انا عندي اكسيد الحديد الأحمر كميات كبيرة كيف يمكن الاستفادة منه في انتاج صبغة المغرة من أين وكيف إبدأ اذا تكرمت بالرد والنصيحة ولك الشكر والتقدير
Can I ask a question? I want to know that this type of pigment can use for cosmetic industry or not
Ummm sort of ochres are not usually toxic so it should be fine but always be cautious of finely powdered pigments
The Alchemical Arts is there literature on that? I just started grinding stones from around and would like to know the safety measures I should put in place!
It would be quite dangerous to do this without a full soil analysis. - many have bacteria or are contaminated with other oxides that can be toxic!
@@nurimj5431 Good question - there are unexpected dangers lurking everywhere - no kidding! Look into grinding turquoise...
audio could use some adjustment. . . i could barely hear you with my laptop speakers.
Hello! When will the new video be a friend? You have very interesting videos! For example, from the roots of the plant red color, it's cool too! Is there a similar option? Thanks and good luck!
New video is on the way my friend.
