- Reddish, brown and yellow earth pigments from a clay mountain in my village.
You can see the place and the process with data about the mesh sizes and comparison of the corresponding particle size.
Sorry for changing the colours in the middle of the process. I was experimenting and I didn't have footage of every step with one colour.

Oh! Very interesting. I don't know if it has something to do with that or not, but the water here is very hard. Thanks for your contribution.
That yellow, especially when dried in powder form is so beautiful. Almost Naples Yellow Hue.
Yes, I love it, the hue and the texture. Thanks for stopping by. 👋
Very well done!! 👏👏👏👏👏I am an Italian artist and I make pigments from the earth find in my region, have already collected 40 different shades. It's a beautiful thing to see that there are others like me in the world! greetings from Sardinia ☺️😃👋👋
☺ I see you've really got the bug, 40 shades are a lot for natural pigments found in your area. Thanks a lot for your beautiful message! It's made my day. Keep enjoying...👋
incredibly satisfying video I am so inspired!!
Thanks! I'm so glad to inspire you. Have fun if you try.
This is so cool! I just got dirt from my backyard and ground it up until my hands cramped lol. This is a much longer process, but looks WAY more effective. Thank you for sharing this
😄 Yeah, it's a long process. Most of the time it's more convenient just buying it, but for the people that enjoy making things by ourselves it's very rewarding.
Thanks for your words.
Absolutely fantastic video, i love the attention to detail!
Thank you for your message. 🙂👋
Sorry for the ads before the video. Now CZcams put them wherever they want. I never wanted to use ads and I don't plan to, for now at least. I prefer other methods of income more directly connected with what I do. Feel free to use Adblock Plus on my channel if you like:

INCREIBLE Y MARAVILLOSO!!!
Gracias por compartir ❤❤❤
Wow, what an incredible video, and what stunning colours. This was amazing. Thank you so much for this tutorial. Do you think I could make pastels, this way, from these pigment powders? What a lot of hard work you put into this video. It is truly admirable. ⭐️⭐️⭐️⭐️⭐️
Thanks a lot for your kind words! I'm not sure about the pastels, I'm a musician and woodworker, I don't know much about paint, sorry. Good luck with it and have fun.
@@RobSanxWoodworks You’re absolutely incredible and I appreciate all the work you put in, and imparting your knowledge to everyone, and yes, I have found out that I could use those beautiful pigments to make pastels, with a bit of a tweak, here and there.
@@jacksprat429 Great. I'm so happy to know that it brings that much value to you, it's very fulfilling. Thanks for letting me know.
@@RobSanxWoodworks You’re most welcome. 🤗👍
Jejeje. Justo estaba investigando como hacer sanguina y tenia duda sobre usar arcilka colorada. Tu video canalizò mis inquietudes y diaipò mis dudas.
Muy agradecida. Saludos desde Argentina
Encantado de que sirva incluso indirectamente para otros usos. Saludos.
Wow I love to see this process of natural pigment extraction . Mother nature has gifted us with so many healing and useful clays and plants ..
You're right! I'm very glad to see the gratitude in your words. Thanks for your message.
Thanks so much for sharing this well thought out and elaborate process with us. I picked up quite a few tips that will make my life easier. 😊 I am curious why you're heating it, though. I have a variety of micron sacks with stiff round openings, but the solid square sifters look much easier to use. They remind me of my large garden soil sifting trey. 🤣 cutting the brush bristles helped immensely. Thanks again.
Thanks. I'm glad it helps. I've seen large wooden sifters on a thrift store, I suppose you mean something like that, yes they are basically that but a little more subtle. 😁The heat helps dissolving the chunks, and it fills me with bliss to know that it's disinfected. 🤭
@RobSanxWoodworks I agree on the boiling. I have kitchen nylon filters at 100, 200, & 300 mesh. I'll be looking for a few sturdier stainless steel sieves now in the 50 to 100 micron range. Thanks.
Great job takes lot of hard work and patience
Yeah, I did it once for fun, but it is a long process. Thanks a lot!
Beautiful pigments, very well demonstrated on how to make the pigments, your lucky to live in such a beautiful location with so much variety of pigments available from the earth, may i ask which location this is?
Thanks a lot. It's a small village in Valencia, Spain. You have my contact information in the about section of this channel in case you need to know more.
Excellent video! Thx for sharing!
You're welcome. Thanks.
What a beautiful place!
Congratulations.
It is! Thanks a lot. 🙂
Artista !!!
🎨 Thanks. Me alegro que te haya gustado.
Very good, loved watching the process
Happy that you enjoyed it. Thanks for the feedback. 🙏
Beautiful and helpful video. thanks.
I'm very glad you think so. Thanks for letting me know.
I hope that you have been able to locate some blue clay!
Thank you for the detailed instructions of your process and the tools/mesh you used. I am just getting started and was concerned about the mineral dust. Wet sieving solves that problem. Much appreciated.
Hey! So happy to hear that. I was also concerned about it, that's why I didn't like the dry sieving part. Maybe for outdoors... Thanks for the message. 👋
I really liked, it is amazing and exhiting to know how paint and varnishes can be made, and i particularly liked the video because of your methodic, explanatory and silent way, thank you.
☺ Thank you very much for your kind words. It motivates me to continue with the channel. I'm so glad it's been enjoyable to you.
Thank you ☺️ that was beautiful
You're very welcome. Thanks. 🙂
I’ve recently gotten into paint making (Watercolor) and so I understand and love videos like this. I use natural earth pigments from France as I’m in France. - nice video 😊
Thanks for your words. I appreciate the feedback. Keep enjoying!
Very interesting ... thank you
You're welcome. Thanks for the comment.
really useful, thank u!
You're welcome! 🙏
Thanks for the information on microns! I needed it to buy a first sieve that would be more or less universal, and couldn't find anything
Very useful video, and beautifully made, thank you
Thank youuu. I'm so glad it helps. That happened to me, I couldn't find enough info, so I thought it would be interesting to show my experiments with precise data so you don't have to waste money on sieves that aren't what you need. Some of them are pretty expensive.
@@RobSanxWoodworks they do cost like a personal jet😁 Thanks again!
Love the footage at the beginning of the colors of soil. New England doesn't have such differences, but last spring I drove across the southern US and saw so many! I've started collecting soils of amazing colors!
WHY ARE YOU HEATING THEM?
Thanks! TravelingArtista
Thank you very much. I'm glad you like it and happy to see your enthusiasm.
I'm heating them for two reasons:
1. To process the hard pieces easier and obtain as much pigment as I can.
2. To disinfect, so I can store it for a long period without worries.
@@RobSanxWoodworks Excellent! Thank you for this information.
You're welcome! Keep having fun. 👋
this is brilliant. Thanks! Great info on mesh sizes. May I ask why you heat up the mixture first?
Thanks a lot. Yeah, I didn't find too much about mesh sizes when I did it, so I wanted to add my experience with them. I'm glad it's helpful for you.
I heated it up to process the hard pieces easier (1:20) and obtain more pigment, and also to disinfect, so I can store it with peace of mind.
@@RobSanxWoodworks Thanks, that is super helpful. (Also I noticed you had answered the question on heating earlier.. sorry.) I previously made them using coffee filters to catch the fine pigment after many rounds of sieving and stirring but your method looks much easier and more effective.
Don't worry, I don't have much work with comments currently and also more comments helps with the discoverability of the channel so feel free to repeat. 😂
Coffee filters work, but for me the problem is that you lose the finest powder that pass through it. And that's precisely the best bit.
Hey thanks so much for this video…one of the better vids I’ve found on Earth Paint making 🙏🏼✨I am currently researching sieves to buy thanks for this wet sieving intro. Just wondering what solution are you adding at 2:40 mins in? Thank you
You're welcome! Thanks for your kind words. It's all water, but I'm using distilled water here. At 7:15 you can see that it wasn't a great idea and I ended up using tap water for the rest of the pigments. Thanks for asking, I forgot to put the subtitle there.
this is by far the most helpful video I have found on this subject, thank you so much for sharing! You have such an amazing array of sieves, might I ask where these are from? And how you choose which to use for different types of stone?
Thanks again :)
I'm very glad it's helpful. Thanks for your words.
I started with the 0.5 mm. sieve because I had it already. Seeing the result with that and with the help of some of the few videos that explain it with a little more detail about it, I bought the other ones.
First I ordered a set of artemia nylon meshes from an aquarium supplies shop, but the order never arrived. So I changed my mind and took the risk of buying the 50 micron sieve in an online laboratory supplies shop from my country. You can buy cheaper ones in non specialized shops if you don't mind a lack of accuracy in the mesh size. For this purpose we don't need that much precision really.
Then I saw that 50 micron was a big step from 0.5 mm. , so I returned to another aquarium shop for something cheaper. I bought the artemia sieves with the black plastic frame and nylon mesh, 300 and 120 microns. There were a couple more in the set, btw.
After that I thought I wanted to dry sieving the result after the wet sieving to loosen the pigment so it looks finer. 50 microns was too fine for that, and the artemia sieves were too small in area, so I bought an 80 micron nylon mesh which is also an artemia mesh but without the frame. I glued it to a wooden frame and it was pretty good for the job.
That was the first and last time I did it and I used the same sieves for every type of earth. I was experimenting all the time and edited the video in the best way possible with that footage.
I've never tried with rocks so I'm not sure if there's any difference in terms of the optimal mesh sizes. I just can say that it's better to use a metal sieve for harder and rougher materials and you can use the cheaper nylon meshes for clay, earth or when the stones are already fine enough so you don't ruin the nylon with it.
thank you for this info! So if I’m understanding correctly, the higher the number, the finer the mesh is? For example, 300 mesh is finer than 150? I think microns work in reverse though? Not sure if the sieves you have are measured in microns or mesh.
Did my first wet sieving with the 60 mesh sieve I had on hand, it’s a good start. Thank your for the information, the inspiration, and for your response!
You're welcome. The sieves are finer each time throughout the process. The first one is in millimeters, and the other ones in microns. If you put them all in the same unit, lower numbers are finer because that's the size of the holes in the mesh.
Its a tedious process but it works, thanks for demonstrating this. btw what kind of oil did you use? is it mineral oil? can it be used with any spirits like alcohol,turpentine or acetone?
My pleasure. Well, for me it was enjoyable for the most part. Not too much during the dry sieving, that's why I prefer this way I suppose. Depends on how you like to spend your time. 😁
It was boiled linseed oil, just because I had too much and I wasn't going to use it. But, as far as I know, you can use any finish or medium you want, for woodworking or art mediums... I used them with oil and water based finishes, and with shellac (alcohol). The same as any other pigment powder of this type you can buy.
Ciertamente la goma laca está por las nubes como la moleta de cristal, pero es lo mejor que hau para xilografia y fijador de tecnicas secas.
Ahora preguntas en una ferreteria por goma laca en escamas y no la conocen asi como tampico la nogalina..

Muy bueno tu canal
Muchas gracias. Bienvenido! 👋
Красиво!
Thanks a lot. 🙏
do you think it is possible to grind minerals? If so, what to mix them with to be able to spread out to paint? thank you
You can but of course it's more difficult. If it's not too hard and you don't mind if you're wasting some of the material, you can try with a mortar. For more advanced methods, here you have a video: czcams.com/video/cahwbEHrZ3c/video.html
About the medium there are different options depending on the project. Is it for painting art, or something else? What's the canvas/surface?
sieving dry like you did with the yellow one is so hard but a small 80 micron sieve is all i can afford at the moment. the rock dust is insane and i'm trying to find a permanent solution rather than using plastic to shield me and my room from the dust
Yes, if you mean sieving dry from the start with 80 micron it must be very hard. Wet sieving is so much easier and if you need an extra step first, I recommend levigation, like you can see at 2:49, which doesn't require any special equipment.
Also, here it is a video, in case that setup inspires you to find your permanent solution without plastic:

Good luck and have fun!
Hello Rob, would you know how colourfast these ended up in the light after 2 years has the colour stain faded? Cheers :)
Hi. I don't have anything to prove it but I bet they're very resistant. They were in the mountain exposed to the sun every day. Some of the bits in certain spots were almost like fired clay, ceramic-like. If they resist that I wouldn't be worried. Cheers.
@@RobSanxWoodworks thank you. Love it
This is super informative and has clarified the process I think will work for me.
Our local riverbed has soft coloured sandstone and other various coloured rocks that I would be interested to see if a pigment could be extracted. I'm on the look out for clay as well. The focus is on being able to make watercolour pigments from these if possible (already making them with commercial earth pigments).
You itemise the meshes used as 0.5mm (500 μm), 300 μm, 120 μm, 50 μm, then revert back to 80 μm to sieve the dry pigment to conserve some of the larger particles and colour. Yet it's already gone through a 50 μm wet?
Where would you recommend I source mesh sieves like these. I see AliExpress sell them so I'm hoping they will be sufficient. Thank you.
I'm very glad it helps.
Yes, it's a lot easier to go through a 50 μm mesh when it's wet, but when it has dried they stick together and form little rocks even using the mortar. If you want the dry pigment to look extra fine you can go with a smaller mesh, but for me I would probably use even 100 μm or so. You can choose to use this same size also in the wet process so you can save some money. If you're going to mix it with water (or any medium) it will disperse better than dry anyway. Especially if you use a glass muller to make sure everything is well ground.
I'm not a painter but I think it could be interesting to experiment with different meshes even within the wet sieving, because for that purpose I like some texture and imperfections, and larger particle size could be good in that case if that's what you're looking for.
The sieves are from different sources. 500 and 50 are from lab supplies which are expensive.
300 and 120, the small nylon ones with black plastic, are from aquarium shops. I think they're called artemia sieve.
80 is also an artemia sieve, but larger format and without support, just the nylon mesh. I built the wood square and glued the mesh. I prefer this format and they also sell detachable plastic supports for them.
AliExpress ones will also work as you don't need the precision of a professional lab equipment. The same as using cheap aquarium stuff.
Have fun! 👋
@@RobSanxWoodworks - the sieves I ordered have arrived and I have processed some weathered sandstone containing haematite and limonite. To accelerate the drying process you boiled the liquid off a bit, would baking in the oven be another option? Thanks.
@@jthomas332 I think so. I just don't like the possibility of staining the oven where I cook. I did it with a small batch while it was dry, to disinfect before trying dry sieving from the start. But I prefer to leave the oven for my bread. 🍞
I mean, apart from getting noticeably dirty I wasn't sure if any toxins might be released with heat. Maybe not, but I played safe in the stove and with the extract hood.
@@RobSanxWoodworks understand. I covered the tray and put it on a low heat for 20 min. It did a great job of removing the moisture and no smells. The resulting powder was re-ground and mulled into a beautiful yellow ochre. I'm absolutely thrilled with the result. The finest mesh I bought was 150μm and it's a tad coarse and feels a little like fine emery paper once dried on paper. I think I'll order a 100, 74 and 50μm just to have the option.
Great video and well put together..im looking at this method for making paint for pottery..im replicating native indian pottery and search for the same colours..presume you are in Spain...were about is the location ? we live near the border in France. searching for a yellow pigment or clay that keeps its colour after firing as all normally turn red.. Thanks
Thank you. Those mountains are in Valencia. But I'm sorry to tell you that this one turns red too. I've just put a little amount directly on the ceramic stove to try and now it's similar to the red one in the video.
I love pottery. I'd like to try someday.
Let me know if you need anything else. Good luck and have fun.
@@RobSanxWoodworks Hello Rob, thanks for the reply and doing a little test.. Only found a tiny strain of yellow clay that stays yellowish after wood firing.. Along the Ebro valley. Valencia town or region? We are in North of the region often.
Can we contact via email mail.

Where do you get your sieves
Metal ones from lab supplies shops and plastic ones from aquarium shops, they're called artemia sieves.
Why cook the pigment?
Here 1:20 I tested if adding hot water is a good way of dissolving the big pieces better. So then I decided to do it that way. Apart from this, it's a way of disinfecting it, so I can be more confident about storing it for a long period of time without worries.
@@RobSanxWoodworks thank you. I just thought that heat might change the hue of the color. I know Yellow ochre will turn to red ochre with heat.
If not, you could've added boiled water with your levitation process to disinfect it instead of cooking the pigment.
Im glad you showed the difference between boiled water and tap water levegation. I had a problem with that.
@@sebastiaantheartartist Well, in my case the difference is between distilled water vs tap water, not boiled vs cold, if it is what you mean.
About the colors are exactly the same. More vibrant with less particle size of course. I don't have technical knowledge for that, but I suppose the heat should be more than that to see a change.
What's the use of making this video when you don't even tell us what the liquid in the syringe was? Oil? Varnish???
8:20 I'm just removing the water.
What's the use of making questions with that lack of respect and gratitude?
@@RobSanxWoodworks no, you added something yellow to the powder and then mixed it in around 14:00. Sorry I'm just not getting answers anywhere and watching 20 min videos and they leave.out important info that I need and I'm so frustrated.
@@buckbeaksgarden761 Ok, that's oil. But that part is just a test, it's not part of the process. The important thing is that the first one is a finish or medium without pigment. Oil or varnish it doesn't make too much of a difference. And the rest are the same oil but with the pigments.
...And apart from that, if the info you're missing is what medium to use for your particular project, you can tell me about it and I'll see if I can give you any advice. But that's out of the scope of this video, I'm just showing how to make the pigment powder. You can do a lot of different things with it depending on your needs.
