slate find application in interiors and exteriors. It is extremely beautiful and more cost effective than most other wall and floor coverings. It renders a very graceful, natural finish to any building or home.
Slate is a metamorphic type rock with a layered structure, allowing it to be cleaved apart into thin sheets. This creates the unique surface texture that shows the natural ridges and layers of the stones structure. Quarried by prying apart layers of stone, the surface exposed is quite colorful, in some cases exposing minerals trapped between the layers of stone. slate are found in black, charcoal, cool greys, browns, rusty reds, green, copper or plum colors.

Slate physical Properties

Slate Stone being a natural stone, there can be variation in color &shade.

Water Absorption :

The capacity of water absorption is not more than 1.0%

Hardness :

Lies between 6 to 7 on Moh's Scale Density 2.32 to 2.42 Kg/m3

color :

Slate is available in many colors – red, green, yellow, pink, gray and white.The reason for the variation in colors being the change in the percentage of

Porosity :

The porosity of slate is almost negligible. Thus slate is almost impermeable.

Slate Chemical Properties

The composition of slate is quite similar to that of sand, that essentially consists of quartz. The natural cementing material which binds the sand together as rock is usually composed of silica, calcium carbonate, or iron oxide. The percentage constitution of each constituent varies between certain limit, which is as follows:

SiO2 93-94%
Alumina(Al2O3) 1.4 to 1.5%
Iron(Fe2O3) 1.5%-1.6%
Lime(CaO) 0.8% to 0.9%
Soda(Na2O) & Potash (Kro) 1.0% to 1.2%
Loss On Ignition(LOI) 1.0% to 1.2%
Magnesia(MgO) 0.2 to 0.25%
