Greenish-blue Stone

Kota Stone is a fine-grained variety of limestone, quarried at Kota district, Rajasthan, India. Many hundreds of mines are located in or near the town of Ramganj mandi and Kota district.

The rich greenish-blue and brown colours of this stone are most popular. It is an excellent building stone. It is mainly used for exteriors, pathways, corridors, driveways, balconies, commercial buildings etc. It is also suitable for use in chemical industries as flooring, wall fixing and lining. Other colors–black, pink, grey, beige.

Polishing

Polishing brings a shine and smoothness to the surface of stone after cutting into pieces of different sizes and thickness.

Limitations

The stone tends to flake over a period of time. However, periodic polishing using polishing wax can eliminate this phenomenon. Also, the stone lacks the luster compared to marble or granite. Kota Stone competes in the market for its lower cost and longer durability.

Another aspect that the Kota Stone loses to Marble and Granite is the size. Its maximum sizes are around 240 cm in length and 75 cm in width. This is due to the physical properties–the brittleness of limestone. So, when flooring is done, especially large spaces, the number of joints are more which is not very aesthetically pleasing.

Since it is limestone it is not resistant to acid and alkali.
