You need to fire treat the raw stones first... to make them easier to grind and attain a more stable oxidation state and final color.

Doesn’t that change the color of many ochres? I know heating after grinding does.

Oxidation state of sediment clay? I mean, it won't change in our lifetimes or nothing. Baking Yellow Ochre will first yield you a Pink umber, (which dries faster than Yellow) at around 500C. 600C to 700C you can achieve burnt umber shades. The raw stuff is still good though, extremally stable up there with gold. Bake for variety of shades, not for lightfastness.

I have collected 8 bags of ochre/umber, sienna clays in North Georgia. They range from white to beige to orange to brown to dark chocolate. I will be removing the sand from them then drying them and making a set of pigments for my daughter's Christmas gift. I have enough product to experiment a little with roasting too. Glad to find your video on the how to process at home. Thank You

thanks for sharing your knowledge, have you considered using a centrifuge to separate particle sizes when making paint? the size of particles are separated based on their density, you can also build a wood model which you spin to create centrifugal force (actual centrifuges can be pretty pricey)

Thank you for sharing ! If making an ink, is the litigation process important in the final color result ? I tried grinding the rock fine enough and mixing with arabic gum and a little bit of water and vinegar. The color on paper is a beautiful yellow ochre and there's texture from the rock not being grounded fine enough but I enjoy it !

Yes but you need to use potassium alum and soda crystals, to attach to the colour in the solution and cause it to precipitate down to the bottom. Then just extra the water by which ever gentle way suits you i.e. coffee filter or just leave it to naturally evaporate. 😘

Hey, i am making pigments using a very dark and bloody coloured iron oxide. The ones you use make it super orangey, but the rust i have is almost blackish red. Its the kind of rust built up on the inside of a metal smoker. I think its a iron 2, 3 oxide mix, but i am unsure. How would i make the darker pigments? Im afraid if i did your method it would become lighter, but i need the deep reds.

You likely have some manganese in your pigment. My area has old iron mines and manganese mines and the combination makes the darkest pigments.

Hey great video! I’m collecting rocks for my river and I try to make pigments. I still refine it with women’s tights few times and it is a fine dust but it’s still grainy when I mix it with oil.... why is this happening?
@TheAlchemicalArts
4 жыл бұрын
I would try levegating the powder by mixing it with water, stir it let it settle for 5-10 seconds and then pour of the lightest particles and leave the heavier grainy stuff behind. If you do this a few times it should help a lot. It may be that the rocks you are using are not suitable and you may need to look for some softer ochres.

The Alchemical Arts I will try the method you showed and I hope it will work! Maybe I need to grind in my muller further but 20+ minutes is a long time for it to still be grainy. Thank you so much!!
