- Kota Stone
Kota Stone is a fine-grained variety of
limestone , quarried atKota district,Rajasthan ,India .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 & lining due to its acid and alkali resistant properties.
Other colors- Black, Pink, Grey, Beige and etc.
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 lusture compared to Marble or Granite. But Kota Stone competes in the market for its lower cost and longer durability.
Another aspect that the Kota Stone looses to the Marble and Granite is the size. Its maximum sizes are around 240cm in length and 75cm in width. This is to do with the physical properties-brittleness of the limestone category. So, when flooring is done, specially large spaces, the number of joints are more which is not very aesthetically pleasing.
