Slate is a fine-grained, very low-to-low metamorphic rock possessing a well-developed fissility (splitting attitude) parallel to the planes of salty cleavage. It is formed by the metamorphism of pre-existing clay rocks such as claystone, shale or siltstone. The most remarkable feature of this rock is that it has cleavage planes that are well marked which enable it to be split manually or mechanically into relatively thin slabs.
Slate is a low-cost decorative stone used for exterior and interior decoration of buildings. It is significantly used in roofing. It is also used as school slate and also as building dimension stone. Slate has an aesthetic value like other dimension stones, granite and marble. Slate has emerged as a low cost alternative to granite and marble which are comparatively expensive. Micaceous and chlorite slates are generally preferred.
Slate comes in a wide variety of sizes and shapes. Common sizes include 12x 12, 12x24, l6xl6 and 24x24 but other custom sizes are also available. Slate also comes as a flagging (random) as well as roofing slate and hand-cut. Slate is at home in any environment from rustic to contemporary, from casual to elegant.
Polished slates are available in a wide range of colours - a finish that opens up a lot of design options. Natural Stone / Slate is not expensive. When you consider that your investment will last a lifetime, slate compares very favourably with most other products.Slate is not dull, nor limited to black or green. It is available in vide variety of different rich and vibrant colours. Slate is not difficult to clean. Slate needs very little care; regular maintenance involves only damp mopping or vacuuming.
Slate is not limited to floors. It can be used almost anywhere - inside or out, residential or commercial. Imagine it as a feature wall, inside the shower, around pools, in an entranceway, on a fireplace. Slate stabilizes temperature variations and is a natural insulator. Unlike ceramic tile, marble or granite, slate is a natural conductor and will absorb the heat from the sun or take on the surrounding air temperature.
It is comfortable and therapeutic to walk on and is also non-slip. Slate is recognized for its low moisture absorption. This also means that with proper sealing it will resist stains from grease and oils.
Slate is also used to form tiles for walkways and gardens. Another common use for slate is found in the recreational field. Because slabs of slate can be ground down to an absolute flatness, slate is often used as the base for billiard and pool tables. A slab of slate is custom-cut to the dimensions of a table and made as level as possible. A layer of green felt is then glued to the top of the slab to provide a playing surface. The slate tablet is by far the heaviest element of a pool table, adding several hundred pounds.
