I don't know what kind, specifically. Ochre covers a wide range of natural earth pigments with different compositions, but usually iron-rich.
I dig this stuff out of cracks in the Canadian Shield for paint pigments. It's naturally colourfast and very close to, if not a little less pure than what's used in commercial paint.
You’re doing a wonderful job! I find you a pretty constant inspiration, I’m sure I’m not the only one.
I seriously love that community, it’s probably my favorite one on the fediverse. I love seeing people make and share art (and art supplies it seems!)
Well now I'm glowing. I hope you share anything you happen to make.
