Natural pigments is a very deep subject and this video barely scratches the surface. My online masterclass "Natural Pottery Paints, Slips & Pigments" will help you learn a lot more about this subject - ancientpottery.how/courses/natural-pottery-paints-slips-and-pigments/
Being impatient and living in a humid climate I have found a few ways to speed up levigation. Depending upon the coarseness of whatever I am levigating I go from a colander to window screen down to an old t-shirt to separate the particle sizes. Only at that point do I let it settle and pour off clear water. The thing is I can stop sieving at any stage of particle size from coarse to extra, extra fine. This is what I came up with after the first time I did it and after a month of waiting for it to dry out enough to use. I tried hanging it up to dry and it took a week in the shade (if it didn't rain) or it turned rock hard in the sun because I didn't have time to check it every hour. So I repurposed old t-shirts, again, sat it in my basement on a stack of old cardboard to draw the water out. Bonus I got moist cardboard to use as a weed barrier in my garden, but that is another story.
Thank you so much for igniting my primitive pottery passion!! I’m going to learn more about the southeastern methods over in nc. Also that mindat website it awesome I found a hematite deposit at my high school
Great video, I buy hematite rocks from the market nearby, my people use them to heal some dermatological anomalies, so as said in the video there is barely no culture that hasn't used hematite as a paint or something.
I find really nice, rich red sandstone chunks where I live in Montana but when I crush and levigate, the paint that comes out is orange/ burnt sienna. Hoping my yellow ochres turn a better red.
I have seen at least a hundred different kinds of hematite just in our area... we have been doing some heavy mineral experiments lately. Love this stuff!
great content as always, made my first sucessful firing this week, i used a gourd scraper and a stone to polish, i dry processed the clay, added temper and fired it in a pit with charcoal, the pieces me and my niece made, were by no means perfect but we had so much fun!, i'm gonna try to make some paint next, thank you for showing me all this knowledge
Very information dense, love it. Question: Over all the years you've been crawling around in the weeds out there, how many rattlers have you said howdy to?
A few, not sure I can come up with a number. I am careful, I look where I step or put my hands, I won't walk through heavy grass or brush where I can't see the ground. I was bit by a rattler when I was 14 and spent a couple days in the hospital, I don't want to ever do that again.
I collected lots of hematite rocks soon after finding you. About 3 years ago now :-o and i still havent processed it. I think this video is a good hint that I should get to work and make some paint, instead of just using the iron oxides that I bought online. I will start tomorrow... if I can remember where I put those rocks. :-D
I think three years is just about enough time, you better get on it. Besides it's almost spring in Australia, sounds like a good excuse to get outdoors.
I did what I was told, and spent yesterday hammering and grinding hematite. I started levigating what I'd processed, and am having the same problem you did with the slow settling. Sadly today is cold and really windy, so I am not going outside to do more. if i tried grinding, all the good/fine stuff would blow away. What do you do with your leftovers, sand stones etc from the processing, chuck it in the garden?
You can't use charcoal as pigment but I have had a few comments about this recently so someone on UA-cam must be suggesting it. Don't believe everything you hear on UA-cam. Also I never use glaze so I can't help you there.
I have a spot where I've found clay that is so heavy with hematite that I just levigate it and use it as a paint but when i get reduction firing down, I'm gonna try it as a clay body.
Red ochre contains unhydrated hematite, whereas yellow ochre contains hydrated hematite. Is there a difference in outcome when using for paints on pit fired pottery?
Sure if you have access to bright red clay you can paint with that. I have a yellow clay that fires bright red and I was just painting designs with that yesterday.
I was going to mention that people usually pre-roast the hematite when they’re going to make iron out of it in order to soften it to be able to be crushed into fine powder. You basically just throw it on a fire and then collected at the end.
Isn't it also possible to roast the hematite over a fire to soften it? This technique is used in iron smelting before crushing the hematite into a powder. I'm wondering if roasting hematite could turn a good-colored but hard hematite chunk into a softer hematite chunk.

As always, loving it! Hematite is also a form of iron ore
I always look forward to your videos where I am both educated and entertained. This is the sort of thing that YT is meant to be. Cheers
Thanks Wes.
Your ceramic creations perfectly capture the blend of tradition and modernity. It's inspiring to see such passion and skill in every piece!

Good tips, thanks!
So that’s where cayenne pepper and paprika come from. Neat!
Another great video! :)
Yes, and it has really kicks up my cooking too! Thanks.

You are welcome and please don't cut open batteries it is dangerous.
@@AncientPottery apparently only lithium ions are combustible dry cells are pretty safe and I watched videos on how to do it right.

Thanks for sharing!
Perfect timing, I just found a great hematite source and was looking for some information about processing.
Glad it was helpful!
Useful information and good advice, thanks. Especially LABEL YOUR JARS. I learned the hard way of course.
I think most of us have learned to label and take good notes the hard way. Thanks.

Yellow ochre is often the brightest red

peace be upon you sir from me
Your video is so beautiful sir tell me please how to make charcoal pigment for pottery and tell me glaze material
You can't use charcoal as pigment but I have had a few comments about this recently so someone on UA-cam must be suggesting it. Don't believe everything you hear on UA-cam. Also I never use glaze so I can't help you there.
You cannot use charcoal as pigment due to its nature being highly flammable.
I have a spot where I've found clay that is so heavy with hematite that I just levigate it and use it as a paint but when i get reduction firing down, I'm gonna try it as a clay body.
Whole video is very nice natural glaze colour material tell me please
This video is literally 18 minutes of me telling you.
Thank you! Great video
Glad you liked it!
Hello , I watched your diy on how to make clay (just dirt) , is there an alternative for the 20% sand that you mixed with the clay you made at the end
🎉so interesting🎉and esthetic
Thank you
Keep going Andy 👏👏👏👏🤩🤩 I learn more things from Andy than those so called professors in university 😂
Red ochre contains unhydrated hematite, whereas yellow ochre contains hydrated hematite. Is there a difference in outcome when using for paints on pit fired pottery?
Interesting. Yellow makes the brightest reds in my experience. I wonder if the chemistry has something to do with that?
13:24 could you make a pot out of just that?
No idea, but it does have a plastic, clay-like texture. More experiments are needed.
Hi Andy, I wonder if there's any evidence of the use of boric acid for ceramic's waterproofing as it is used for curing casting crucibles
Do you paint your pots with the clay/pigment mixture once it is bone dry or does the clay body need to be leather hard?
I prefer to paint bone dry but you can paint when leather hard.
@@AncientPottery OK, thank you for the clarification!
👍
👍👍
Hi Andy, I have a quick a question. Can i decorate ivory (very light brown) clay with bright red clay because im not sure if here i live have Hematite
Sure if you have access to bright red clay you can paint with that. I have a yellow clay that fires bright red and I was just painting designs with that yesterday.
@@AncientPottery Thank you, I appreciate that you reply, now I will try it too!
Potters use hemitite with the bee weed paint. Do you know how they do it. Where can I find d hemititr in AZ. I'm in AZ this weekend.

Andy! Are you playing "orange face" in a nearing election? 😂🤣
Sorry, couldn't help myself. Have a great day! ✌️
Oh no!!! I'll get both the Democrats and the Republicans mad at me!
I thought hematite was shiny black rocks?
It can be
😄👍
All this clay is keeping your skin looking young lol
LOL
Not a big deal, but it’s min dat not mine dat. As in mineral collectors.
Thanks I never heard it pronounced.
