Where can I find red Ochre?
Ochre occurs naturally in rocks and soil — essentially in any environment where iron minerals have pooled and formed, Pettitt said. “It can be found in valley edges, eroding out of cliffs [or even] in caves eroding out of the bedrock,” Pettitt told Live Science.
Is Red Ochre toxic?
non toxic. Ocher is not considered toxic, but care should be used in handling the dry powder pigment to avoid inhaling the dust.

Where can I find natural ochre?
If your forest has a creek, lake, or river, head to that area and look along the shore for pebbles and clays. Ochre forms where natural metals oxidize over time and will appear as a different color than its surrounding soil. Most ochres are a shade of rust or yellow. Keep your eye out for these as they’re the BEST!

The secondary oxidized iron mineral, hematite or limonite, are the foundation of ochre. Hematite makes red ochre and limonite makes yellow ochre. So, the chemical weathering of deep Earth minerals, like olivine and pyroxene, and their rocks, creates red and yellow-coloured iron oxide mineral pigments as a by product.

A cavern opens from the pit and the miners tunnelled out many small caves and galleries as they followed the red and yellow ochre seams. The mining method here was to hit the rock with heavy stone mauls and dig the ochre out with fire-hardened pointed wooden wedges.
