Hematite is large-lamellar aggregates with multidirectional leaflets, sometimes replaced by goethite. It belongs to the group of natural pigments that have a high iron content (20-50%). The paints with different shades of red are extracted from it.
The very high iron content in the composition (82,5%) and the low content of other elements confirm the natural origin of this sample.
Fragments with hematite were split off the pieces of initial raw materials. Fragments were grinded up and then they were used for the paint manufacturing.
The sample of hematite has a smoothing along the contour.
