About Slate Stone

Slate stone falls in the category of metamorphic rocks that underwent a transition from the igneous and sedimentary rocks. Its structure is homogeneous, fine-grained and foliated. It is generally characterized by the presence of varying textures over the rock surface and has numerous available natural shades. As the minerals are elongated and flat at the plane of cleavages, this natural stone can be split into thin layers or flakes which are subsequently used for a plethora of stone applications such as veneers, ledge panels and mosaics.

This stone is normally available in grey color in masses, however, black, brown, cyan, purple, brown and green are a few other colors that shimmer the slate. Almost 90% of the European housing has slate roofing due to excellent thermal and chemical stability.


Good Electrical Inulator
Highly durable
Low water absorption
Requires low maintenance
Chemically inert


Due to extremely low water absorption index, natural slate is highly preferred as a roofing material in homes ( most preferably in Europe and
the UK ). Other sites where the slate and its tiles find their usage are as follows:

Owing to its electrically and thermally inert properties, slates can be used in electrical switchboards and high power relay circuits.
Highly used for blackboards in schools and colleges even today.
Excellent durability paves a way for its application in countertops, table tops and flooring.
A wide range of appealing colors and easy workability makes them suitable to be used for crafts work ( jewellery, picture frames, mirrors, coasters, etc ).
Slate stone veneers ( which are practically thing sheets of stone backed by a fiber backing ) that are hardly 1.5 kg in weight bearing all the properties of a slate stone can be used in places where a stone tile is practically not feasible.

Types of Polishes

When the slate is freshly quarried, the natural pleasing texture that appears on the surface is the natural cleft finish.

Satin- like finish imparting a smooth, appealing surface to the slate stone using wet diamonds or stones is the honed texture.

A weathered, aged finish obtained by tumbling the slate with sand/ pebbles, etc. with water in huge drum- like structure repeatedly is the tumbled finish

When machines are used for gauging the thickness of the tile leaving a few marks on the surface, the resultant finish obtained is the machine/ sawn cut finish
