Current Research

Integrated use, behaviors and life-force of ochre (iron rich) pigments:
+ hematite (Fe2O3)
+ goethite (FeO(OH))
+ limonite (FeO(OH)·nH2O)
+ vivianite (Fe2+3(PO4)2·8H2O)
+ magnetite ( Fe3O4)
+ soils, clays, umbers, shales, mud and other iron-rich earth materials

Ritual use of red ochre in end-of-life preparation, burials, ceremony and healing.

Creative medicine process of iron oxides at various scales (internal, external, aesthetic, environmental, biological, cellular, cosmic):
+ pathological accumulation and release (in human body, especially brain, nervous and womb systems)
+ toxic remediation (soil, wastewater, water and biome restoration)
+ iron (+ oxygen) chelation techniques
+ mineral-based therapeutics utilizing foraged ochre
+ protective and regenerative capabilities
+ psychological impact of working with ochres

Cross-cultural exchange and revitalization through integral material color and ochre

Historical comparative ritual red mineral pigments (besides ochres):
+ cinnabar (HgS)
+ vermillion (synthetic HgS)
+ realgar (As4S4)
+ minium/red lead (Pb3O4)
+ copper reds

The role of pigment color and transformation in alchemical transformation

Translations of ancient Ugaritic texts (ca. 1300 BCE, Syria, at dawn of the Iron Age) using material pigment for significant climate-oriented healing rituals, featuring the goddess Anat.
