What is Red Iron Oxide?

Hematite is an important ore of iron and it's blood red color (in the powdered form) lends itself well in use as a pigment. Hematite gets its name from a Greek word meaning blood-like because of the color of its powder. Ancient superstition held that large deposits of hematite formed from battles that were fought and the subsequent blood that flowed into the ground. Crystals of Hematite are considered rare and are sought after by collectors as are fine Kidney Ore specimens.
Hematite is the most important source of iron ore in the world. The production of iron has been important to nations of the world for over 2500 years. Today the addition of other minerals to iron has lead to the production of steel which is vital to the economy of the major countries on Earth. Hematite has a red or black color but the streak is always red. The iron in the hematite turns red when it comes in contact with water and oxygen. In other words this rock is rusted!!

History & General Information About Red Iron Oxide

The name Hematite comes from the Greek word haima meaning blood, in allusion to its color when in powdered form.
Hematite has been used for thousands of years as amulets and talismans. It was used by the ancient Egyptians in religious ceremonies, and was used as an inscription stone for passages from the Book of the Dead. Hematite was also said to give success in petitions and lawsuits, and to give protection and strength and luck to soldiers.
Hematite is the major ore mineral of iron. It is also used as a pigment in paint, and in polishing compounds.
The ancient Egyptians used Hematite in the creation of their magical amulets such as the carpenter stone and head rest amulets and several heart amulets. Some of these amulets were treatments for madness and inflammation. The Greek word haima, which means blood, is the root of Hematite’s name and originates from the stone’s dark red streak. Hematite relates to the Mars, the Roman God of War. The Romans glorified Mars more than the Greeks did who loathed him and knew him as Ares. Warriors in Roman times used Hematite as protection during battle. So strong was their belief in the power of Hematite to protect them that they thought it could even make them invincible. Some cultures even believed Hematite formed from blood that had fallen on the ground of a battlefield. Red Ochre is a paint that originated in Native American cultures, who used it as a face paint.
Hematite ranges in color from a reddish-brown to gray and even black. The most widely available forms are the result of weathering iron bearing minerals. Hematite often occurs with intermixed layers of quartz.
Named from the Greek word for blood, hematite often coats igneous and sedimentary rocks with a reddish color similar to rust, a form of hydrated iron oxide. The hardness value of Hematite is 5.5 to 6.5.
This mineral is abundant in iron mines in Iran..
The astrological signs of Aries and Aquarius are represented by Hematite.
Hematite was used for thousands of years as amulets and talismans and was used by Egyptians in religious ceremonies. Some believe hematite enhances physical energy and vitality. It’s believed to calm emotions and boost self-esteem. It is also said to enhance memory and intellect. Some say it helps with mental clarity and concentration and it’s sometimes used for help when studying. Some believe if you hold a piece of hematite and ask a question, the answer will come to you. It’s been thought that hematite could help a person win a petition or lawsuit and that it would provide protection and strength to soldiers in battle. It works best when work on a belt.
Medicinally hematite has been used to calm hysteria, cure blood diseases, soothe skin ulcerations and burns, treat bilious disorders and help inflammation of the eyelids.
Hematite is commonly found throughout the world. The primary source for hematite is a sedimentary deposit in IRAN. Hematite physically occurs in many forms: specular ore (steel gray color, shiny crystals); micaceous hematite (gray, scaly flakes), red ocher (soft, fine-grain, red powder); kidney ore (massive, gray botryoidal form), and pencil ore (gray, fibrous crystals). Because hematite has a high iron content (70%), it is primarily used for smelting iron. Hematite has been used since ancient times as a red pigment in paints and glazes. It was also used for seals, beads, and small carvings since the early 3rd millineum. Hematite is still used as a paint pigment. It is also used in jewelers' rouge for polishing glass. Hematite can be used to produce the sparkle in aventurine ceramic glazes.
Hematite is one of the most common minerals. The color of most red rock, such as sandstone, is caused by small amounts of Hematite. It may also be responsible for the red color of Garnet, Spinel, and to some extent, Ruby.
All non-crystalline forms of Hematite are supposedly transformations of the mineral Limonite that lost water, possibly due to heat.
Hematite is rather variable in its appearance - it can be in reddish brown, ocherous, masses, dark silvery-grey scaled masses, silvery-grey crystals, and dark-grey masses, to name a few. What they all have in common is a rust-red streak.
Hematite has a metallic or earthy luster. The hardness of hematite is about 5 on Mohs hardness scale. It has no cleavage and breaks with an uneven fracture. The reddish landscape of Mars is due to the oxidized iron on its surface. This tells us that water and oxygen must have been present on Mars at one time.

Red Iron Oxide Geological Setting

Large ore bodies of hematite are usually of sedimentary origin; also found in high-grade ore bodies in metamorphic rocks due to contact metasomatism, and occasionally as a sublimate on igneous extrusive rocks ("lavas") as a result of volcanic activity. It is also found coloring soils red all over the planet...

Metaphysical Properties of Red Iron Oxidee

Hematite is said to enhance one's physical energy and vitality, and to calm emotions and boost self-esteem. It is also said to enhance memory and intellect. Hematite is said to help strengthen the circulatory system and to help in the treatment of blood and kidney disorders.

Color

Hematite is a mineral appearing as metallic gray, red gray, red brown with a metallic luster; it may even look more like a metal than a mineral when encountered in nature. The name Hematite originates from the Greek word for blood, haima, which refers to the dark red color of the mineral’s streak. When crushed, Hematite will turn water red. Specular Hematite (Hematite with a reflective finish) has iridescent colors in its finish. Thin slices of Hematite appear red and transparent.

Crystal

Hematite crystals are members of the Trigonal System group, which is a subset of the Hexagonal system. It is also conchoidal and may appear as a phantom within other crystals.

Forms

Hematite appears in many forms in nature, such as Kidney Ore, a bumpy ore that has an appearance likened to a kidney; Hematite Rose, a formation with crystals in the shape of petals; Tiger Iron, a sedimentary rock with Hematite mixed into its multiple layers; Oolitic, sedimentary deposits of small, circular Hematite grains; and Micaceous Hematite, a scaly, shiny stone valued for decorative uses. Its soft Earthy, form is called Red Ochre. Hematite often appears within other crystals such as Aventurine or as phantom crystals.

Occurrence & Diagnostic of Red Iron Oxide

Hematite occurs in many types of igneous, metamorphic and sedimentary rocks.
The largest and most economically important hematite deposits are mainly of sedimentary origin, forming from the weathering of iron bearing minerals. In these sedimentary deposits, hematite is thought to have precipitated from lakes or seas by organic and/or chemical processes. The hematite often occurs with intermixed layers of quartz or chert (sometimes as the chert variety jasper).
Hematite often occurs in metamorphic rocks which formed from ferruginous sediments, and in contact metamorphic deposits.
In igneous rocks hematite occurs as accessory grains in granite. It also occurs as euhedral crystals associated with quartz deposited by volcanic gases and by high temperature hydrothermal solutions.
Hematite also occurs as inclusions in a variety of other minerals, sometimes forming highly valued gem and lapidary materials such as sunstone, which is a transparent gem variety of plagioclase feldspar which can contain minute hematite or goethite inclusions which reflect light creating a sparkling sheen.

Red Iron Oxide Usage

Painting
Forgery
Drilling
Hematite, with its high iron content is a very useful mineral. As just mentioned, its chemical composition contains a high percentage of Iron (70%) and it is the primary ore used to create Iron. Beyond its use as an ore, jewelers appreciate its shiny luster for creating engravings, cameos, cabochons, beads and imitation diamonds. Red Ochre is a pigment created from Hematite that was used in Native American cultures for face paint.
Hematite is the principle ore of iron. Huge quantities are mined yearly for industrial production. Hematite was largely used in the past as a red and brown pigment, although nowadays cheaper sources have been substituted. Hematite also has gem uses. It is cut and polished into cabochons for jewelry and ornaments, fashioned into beads for bracelets and necklaces, and carved into ornamental figures.
