Magnesite can be white, grayish-white, yellowish, brown, faintly pink, lilac-rose; colorless in transmitted light. It's hardness of the Mohs' Scale is 3 1/2 - 4 1/2.
Mohs' Scale (pronounced /ˈmōz ˌskāl,ˈmōs ˌskāl/ or "moes scale") is named after Freidrich Mohs, a mineralogist who invented a scale of hardness based on the ability of one mineral to scratch another. Rocks are made up of one or more minerals. According to the scale, Talc is the softest: it can be scratched by all other materials. Gypsum is harder: it can scratch talc but not calcite, which is even harder. The hardness of a mineral is mainly controlled by the strength of the bonding between the atoms and partly by the size of the atoms. It is a measure of the resistance of the mineral to scratching, the Mohs scale is for natural minerals. For manufactured products other measures of hardness are better. Diamond is always at the top of the scale, being the hardest mineral. There are ten minerals in Mohs scale, talc, gypsum, calcite, fluorite, apatite, feldspar, quartz, topaz, corundum and for last and hardest, diamond. Because the Mohs scale was made long ago, it is not exactly correct - for example, several minerals are now known to be harder than the diamond. The Mohs scale may not be perfect, but field geologists still find it very useful.
THE FLUORESCENCE OF MAGNESITE You will notice one of the photos shows fluorescent material of lime green - that is the of the magnesite that we collect in Arizona. .
Radioactivity is a part of our earth - it has existed all along. Naturally occurring radioactive materials are present in its crust, the floors and walls of our homes, schools, or offices and in the food we eat and drink. There are radioactive gases in the air we breathe. Our own bodies - muscles, bones, and tissue - contain naturally occurring radioactive elements. Man has always been exposed to natural radiation arising from the earth as well as from outside the earth. The radiation we receive from outer space is called cosmic radiation or cosmic rays. We also receive exposure from man-made radiation, such as X-rays, radiation used to diagnose diseases and for cancer therapy. Fallout from nuclear explosives testing, and small quantities of radioactive materials released to the environment from coal and nuclear power plants, are also sources of radiation exposure to man.
On average, our radiation exposure due to all natural sources amounts to about 2.4 mSv a year - though this figure can vary, depending on the geographical location by several hundred percent. In homes and buildings, there are radioactive elements in the air. These radioactive elements are radon (Radon 222), thoron (Radon 220) and by products formed by the decay of radium (Radium 226) and thorium present in many sorts of rocks, other building materials and in the soil. By far the largest source of natural radiation exposure comes from varying amounts of uranium and thorium in the soil around the world. The radiation exposure due to cosmic rays is very dependent on altitude, and slightly on latitude.
We are exposed to ionizing radiation from natural sources in two ways: We are surrounded by naturally-occurring radioactive elements in the soil and stones, and are bathed with cosmic rays entering the earth's atmosphere from outer space. We receive internal exposure from radioactive elements which we take into our bodies through food and water, and through the air we breathe. In addition, we have radioactive elements (Potassium 40, Carbon 14, Radium 226) in our blood or bones. Additionally, we are exposed to varying amounts of radiation from sources such as dental and other medical X-rays, industrial uses of nuclear techniques and other consumer products such as luminized wrist watches, ionization smoke detectors, etc. We are also exposed to radiation from radioactive elements contained in fallout from nuclear explosives testing, and routine normal discharges from nuclear and coal power stations.

With all that said... the magnesite that we collect in Arizona is white with black veins and is beautiful!
This is what we do...
With environmental consciousness in mind, our fabrics are all printed using completely water-based inks. This means no chemicals or solvents are used. We transfer those images onto luxurious fabric using ecologically safe transfer sublimation inks that provide vibrant color. The printing process uses no water and uses non-toxic bio-degradable inks. Our heat fixing procedure fixes the colors and prints, avoiding the downsides of steaming, such as excess or contaminated water returning into the waste system. The textile industry is rife with sustainability problems: from the use of toxic inks and wasteful practices for materials and water, to a race to utilize the cheapest materials such as vinyl—no matter the environmental impact. Our print-on-demand process is designed to minimize fabric and ink waste. Reducing the use of materials, energy and water by choosing a pigment printing process instead of reactive dye.
Making use of stone that we personally collect, cut and polish to a mirror finish, coupled with high powered lenses, we transport the viewer into a microscopic world, far beyond what the naked eye perceives. The diversity, originality and beauty of what is revealed defy description. Those images are then transferred onto a variety of mediums. Consider textiles that are transformed into decor including decorative pillows, bedding, table linens, for both home and commercial use. And fabrics for the fashion world. GEO originals has opened the door to a realm of beauty crossing all genres with endless applications.
Choose your favorite(s) images, choose your fabric and let us know how many yards! We will also provide additional custom order fabrics upon request (please contact GEO originals).
