Aragonite Uses

Soil Conditioning

• High in calcium, low in magnesium, and free of heavy metals and other toxins, aragonite is a widely used soil conditioner. It reduces acidity that could otherwise damage crops, and it can also serve as a deterrent to mice, squirrels, moles and chipmunks when applied to newly planted bulbs and flowers. Some farmers use aragonite in place of lime, because it performs the same functions without producing harmful environmental side effects. Furthermore, it costs about the same as lime, and does not require mixing with other soil additives, like silica.

Feed

• Aragonite is a common source of calcium in chicken feeds. In its coarse-grade form, it is appropriate for layers, who need plenty of calcium to produce strong shells. The fine-grade mineral is appropriate for broilers.

Household Products

• Because it's nontoxic and mildly abrasive, aragonite is often a component of toothpaste and tooth powders. It's also common as an acid-neutralizing agent in antacid tablets.

Industrial Applications

• Aragonite serves as a scrubbing agent for coal-fired power plants, due to its ability to trap polluting sulfur emissions. In addition, aragonite is an important ingredient in the production of gypsum, which is necessary for the manufacture of drywall and cement.

Glass Manufacturing

• Aragonite is a component of many common glasses, including soda-lime container glass. It also shows good results in the production of aircraft windshields, and laboratory glassware for medical and pharmaceutical uses. It provides a very clear and transparent glass due to its low iron content, and its low melting point gives it good adhesion qualities when mixed with other materials.

Ornamentation

• Aragonite lends itself well to the carving and shaping of ornamental objects like statues, paperweights, crucifixes and bookends. It also has an appealing warmth and smooth texture when finished into smaller jewelry pieces.

Healing Charms

• Aragonite appeals to some members of the new age movement, who credit it with the ability to reduce stress and anger. When made into charms and worn on the body, it is believed to foster feelings of self-confidence and a positive outlook on life. Some people believe that aragonite can even reduce chronic fatigue and prevent hair loss.
