In ancient times, green was offered to artists in the form of minerals such as natural green clay and malachite. The ancient Greeks created copper greens by exposing copper to acetic acid and scraping off the green crust that formed. Copper green remained one of the most widely used green pigments until the 19th century, when emerald green, cobalt green and emerald green were discovered. All three pigments were an integral part of the Impressionist palette. The green spectrum can be mixed with a variety of blue and yellow pigments, but single green pigments are still useful, and they can be used as a starting point for mixing other greens, or to neutralize intense reds.
Also known as chromium oxide, chromium green oxide, chromium trioxide or chromium, chromium oxide green is one of the four oxides of chromium. This stunning green pigment has a place on any artist's palette, valued for its permanence and opacity, and it is one of the most stable pigments available. Because of its opacity, it is widely used to add color, but it also has heat-resistant properties that make it ideal for many industrial uses in paints, coatings, inks, ceramics, refractory materials and specialty glass manufacturing.
1. Green chromium oxide is a paint pigment
Green chromium oxide is commonly used in industrial paints that require a lot of wear and tear. For example, military vehicles are coated with green chromium oxide paint. It retains its color under high temperature and light conditions, making it ideal for outdoor applications.
2. Green chrome oxide adds color to glass products
When manufacturing glass, the addition of green chromium oxide causes the glass to - you guessed it - turn green. The higher the concentration, the more intense the color. A commercial example of this is a wine bottle. It also allows some light protection to preserve the flavor of the wine. Green chromium oxide is commonly used in the production of refractory bricks for metallurgy and glass furnaces/kilns because it has a melting point of 2300°C.
3. Green chromium oxide adds color to plastic products and ceramics
Not only does it add color to inks, glass and paints, green chromium oxide also gives a forest green hue to plastics (e.g. soda bottles) and ceramics. It mixes well with clay and can be used as a component of glazes.
4. In paste form, green chromium oxide is used as an abrasive for sharpening
In paste form, green chromium oxide is used for polishing glass and sharpening metal blades. It is used as an abrasive for razors.
