Slate is a homogeneous, fine-grained, foliated metamorphic rock, which originated from sedimentary rock consisting of volcanic ash and clay. Broadly speaking, slate is formed out of volcanic lava that settled over clay deposits. Further heating of the clay deposits and drying of the resulting mixture in layers led to its formation. Commonly occurring in different shades of grey, slate also exhibits other colours like purple, cyan and green. As per the requirement, slate can be divided into slabs that can be further split into thin sheets.

Since long, slate has been used for various applications with the most common one being as roof shingle in its natural form. Probably, one of the lowest maintenance flooring materials, slate is easy to clean and is a good conductor of heat. Its natural anti-skid and low water absorbance features along with resistance towards cracking, chipping and abrasion make it a popular material for both indoor and outdoor applications, especially in Europe. Suitable for residential as well as commercial projects, slate can be used for roofing, flooring, wall cladding and also to build shower enclosures and pool surrounds. Its other usage may include the creation of tombstones, memorial tablets and gravestones.

In the context of India, slate occurs in the states of Rajasthan, Himachal Pradesh, Haryana, Madhya Pradesh and Andhra Pradesh as well as a few states in South India. Although in Rajasthan, major deposits of slate are confined to the districts of Ajmer, Alwar, Bharatpur, Sawai Madhopur, Tonk, Udaipur, Chittorgarh and Churu, it is Alwar, where export-quality slate is found.
