Red ochre, Fe 2O 3, takes its reddish colour from the mineral hematite, which is an anhydrous iron oxide. Purple ochre is identical to red ochre chemically but of a different hue caused by different light diffraction properties associated with a greater average particle size. Red oxides or red ochres are hematite-rich forms of yellow ochres, commonly formed from aerobic natural weathering of iron-bearing minerals. Prehistoric and Historic Uses
Colour Story Red Ochre Articles Winsor & Newton
Ochre (pronounced OAK-er) is clay pigmented by hematite, a reddish mineral that contains oxidized iron, which is iron that's been mixed with oxygen, said Paul Pettitt, a professor of paleolithic. The Red Ocher people were an indigenous people of North America. A series of archaeological sites located in the Upper Great Lakes, the Greater Illinois River Valley, and the Ohio River Valley in the American Midwest have been discovered to be a Red Ocher burial complex, dating from 1000 BC to 400 BC, the Terminal Archaic - Early Woodland period. In Ancient Egypt, Red Ochre was used in celebrations as a symbol of life and victory and was used as an early form of cosmetics by women. In classical antiquity Red Ochre was known as Pontus Euxinus (from the Pontine city of Sinope in a region that is now known as Turkey). Smeared on shells, piled in graves, stamped and stenciled on cave walls from South Africa to Australia, Germany to Peru, ochre has been a part of the human story since our very start — and perhaps even earlier. For decades, researchers believed the iron-rich rocks used as pigment at prehistoric sites had symbolic value.

Vermilion pigment Natural red pigments Red pigments are materials, usually made from minerals, used to create the red colors in painting and other arts. The color of red and other pigments is determined by the way it absorbs certain parts of the spectrum of visible light and reflects the others. Ochre pigments were, and still are, widely used in paint and artwork. Many of the red and yellow pigments in rock art panels around the world are made with ochre-based paints. Red ochre use in caves, which is a hallmark of ice age art, begs the question: what is the significance rock and cave as locations for the red ochre handprint? We have already mentioned the auditory and echo like properties of the caves. But many later paintings are outside. In the Canadian Shield, the vision site such as the mountain itself. This paper evaluates red ochre phenomena as a fossil indicator for developments of human capacities and red color choice in cultures. The archaeological record reveals that, from Early Palaeolithic to historical times, the collectors and users of red ochre have always been a distinctive minority (probable exceptions being the Magdalenian and Paleo-Indian peoples). Nevertheless, red ochre.

Red ochre is composed mailnly of iron oxide, hematite which word comes from Greek, hema meaning blood. Used from prehistory and throughout history, these permanent pigments can be safely mixed with other pigments. Ochres vary widely in transparency; some are quite opaque, while others are valued for their use as glazes..

Archeological excavations led by Wyoming's state archaeologist and UW researchers have confirmed that an ancient mine in Southeastern Wyoming was used nearly 13,000 years ago to collect red ocher. This discovery means that the Powars II site is the oldest documented red ocher mine and the oldest mine in North and South America. Wyoming Public Radio's Kamila Kudelska spoke with Wyoming State.

Red ochre and early humans Already 200.000 to 100.000 years ago Neanderthal people in Europe as well as early modern humans in Africa painted their body with red ochre mixed with fat. They did it long before modern man developed significant artistic skills and interest in sophisticated rituals. More "mundane" or "domestic" uses of red ochre (derived from hematite, Fe 2 O 3) are known from the ethnographic record of modern hunter-gatherers, for instance, as (internal and external) medication, as a food preservative, in tanning of hides, and as insect repellent ( 3 - 9 ).
