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.
