Magenta

== Description ==
A synthetic aniline dyestuff that is also called fuchsin. Magenta was the second synthetic dye material to be produced from coal-tar derivatives. It was first noticed by Natanson in 1856. Then in 1859, Verguin patented a large scale production method for making magenta by oxidizing crude aniline with stannic chloride, a tanning solution. Magenta is a dark green water soluble powder that oxidizes to forms a deep red fugitive dye. It is used to color textiles and leather and to stain bacteria. Magenta was formerly used in watercolor paints but has since been replaced by colors with better lightfastness properties.

Magic Marker

== Description ==
[Binney & Smith] A registered trademark for a brand of felt-tip pens. Magic Marker pens were invented by Sidney Rosenthal and first introduced in 1952. They are odorless and nontoxic, but the colored dyes are usually not lightfast. Magic Markers have been used in drawings, architectural renderings, and documents. The name 'Magic Marker' has been licensed to Binney & Smith of Crayola fame since 1989.

Magna Plastic Colors

== Description ==
[Bocour Artists' Colors] A brand name for a series of acrylic paints prepared from pigments dispersed in n-butyl methacrylate resins and diluted with turpentine, mineral spirits, xylenes, and toluene. The paints dry rapidly to a hard, matte, nonyellowing film. Released in 1947, Magna colors were the first commercially available synthetic resin paints. In the 1950s, the formulation was changed to include small amounts of beeswax for added paint body (Lodge 1988). Several famous painters, including Morris Louis, Kenneth Noland, and Roy Lichtenstien, were known to have used these paints (Learner 2004). Bocour discontinued Magna Colors in the mid-1970s (Crook and Learner 2000). A similar formulation, called MSA Conservation Paints, is made by Golden Artist Colors.

== Description ==
Common name for magnesium oxide (periclase) in the 19th century (Schur 1985). Magnesia, however, has also been called magnesian earth as well as loosely used as a synonym for magnesite (magnesium carbonate). Fine-grain, freshly calcined magnesia has been used as an abrasive, but coarse magnesium carbonate particles that readily form in the presence of air and moisture can cause scratching.

Magnesite, natural

== Description ==
A naturally occurring mineral composed of magnesium carbonate that is the primary commercial source of magnesium. Magnesite deposits have been mined in Russia, Austria (Radenthein), Greece, Norway, India, China (Liaotung); Australia, Canada (Quebec) and the United States (Nevada, New Mexico, California, Alaska). The hexagonal mineral usually occurs in large masses. Magnesite can be transparent to opaque with colors of white, yellow, gray or pale brown due to the presence of impurities. It has also been dyed to imitate other stones. Most magnesite is formed from the action of carbonated water on magnesium-rich ores. Powdered magnesite is used as a filler and inert pigment. Blocks of magnesite are used as a refractory material for furnace linings. Calcined magnesite is used in oxychloride cement.

Magnesium

== Description ==
An alkaline earth metal that is one of the most common elements in the earth's crust at 2.1% by weight. Magnesium is found naturally in the following minerals: Magnesite, carnallite, dolomite, epsomite, and kieserite. Magnesium salts are also dissolved in seawater. Magnesium was first isolated in metallic form by Sir Humphrey Davy in 1808. The lightweight silvery metal oxidizes slowly in moist air. Magnesium is used for the manufacture of lightweight metallic alloys, fireworks, flashbulbs, optical mirrors. Magnesium salts are used as heat-resistant and insulating materials and as fillers in paper, cements, ceramics, glass, and paint.
