The word "calcite" is derived from the Latin word calx and the Greek word chalix, which means lime. Calcite mineral is commonly found in limestone and marble. It is a colorless or white mineral when pure, but due to the impurities present in it, this mineral can be found in many colors, like red, yellow, green, honey, pink, lavender, black, brown, or blue. This mineral can appear transparent, translucent, or opaque. Calcite can have luster that can be vitreous to dull, and many crystals, especially the colorless ones, are vitreous, while the fine grained mostly are seen dull. It can be scratched readily by a knife blade or a geologic pick. These were the physical properties of calcite. But, most calcite uses can be attributed to its distinguishing properties, like it has a good hardness level, is readily dissolvable in certain materials, and has healing properties.

Limestone blocks were used for making primary construction material while making the pyramids. Now, rough and polished limestone and marble is used for making prestige construction monuments. For making modern buildings, calcite in the form of limestone and marble is used for producing cement and concrete. Such materials are easy to mix and transport, and are used to make a slurry mixture that hardens fasts and is very durable.

Marble is an attractive construction material that has been used to make many monuments and sculptures throughout the history. The lack of significant porosity of marble allows it to stand up well to extreme temperatures and due to its low hardness level, one can easily carve it. Marble has been used to make many small figurines, especially the Mexican onyx variety, and it is also used to make gigantic pyramids. Today, it is used to make statues, benches, fireplace mantles, stairways, etc.

For Making Medicines
