Slate tiles were used heavily in 19th century UK building construction for their versatility and durability. In our Guide to Slate, you’ll find out how the stone is made, where it comes from and how to care for your tiles in your home.
FORMATION OF SLATE
Derived from an original shale-type sedimentary rock composed of clay or volcanic ash, Slate is a fine-grained, homogeneous rock formed by low grade regional metamorphism.
The natural marks and tones of Slate create a multitude of colours from coppery rust through to deep black meaning no two pieces of stone are alike.
SOURCING OF SLATE
Located midway between Jaipur and the Taj Mahal in Agra, multi-colour Slate is quarried in an area called Kund which is best known for its forest and wildlife as well as being the largest area of Slate producers in India. Slate can also be quarried from other areas of India and Brazil.
PRODUCTION OF SLATE
Slate is procured from the quarry in blocks with the final blocks being chosen for their colour and quality by experts. The slate blocks are then split along the visible layers to produce slimmer slabs. These slabs can then be cut by machine to the required size and calibrated to give a definite top and bottom to a tile, making laying easier.
BENEFITS OF SLATE
In its natural form Slate can be brittle and prone to chipping due to its thin layers, however once fitted Slate becomes a robust and durable natural stone. The natural colourways don’t show any wear and tear and if sealed and maintained properly, it will last for years.
