Natural Slates

Natural Slates

Natural Slates are fine-grained metamorphic rock of argillaceous origin formed by the composition of mud and stone sediment that splits into thin, smooth-surfaced layers. Slate Stones are chemically a multi-mineral rock made of a composition of minerals and colloidal substances. The mineral composition essentially consists of members of Mica group commonly sericite & muscovite,and and accessory minerals such as oxides, calcites, minor amounts quarts and feldspar along with some contents of ferro-magnesium minerals. The content of silica is normally poor. The Clay group commonly consists of paragonite, chlorite & kaonilite. This fine grained meamorphic rock formed of above composition of minerals and other organic substances has been hardened by heat and pressure. Since the geolgical process varies greatly from place to place, Natural Slate Stones hardness and porosity varies quite a bit.

Slate stones characteristics vary with source. It may be black, green, yellow, brown, red or mottled and is relatively dense. Many natural slate stones that are available today have wide ranging physical characteristics and overall suitability.

The natural slate stone differs in its density, tensile strength, absorbency and abrasion resistance.

MOQ:1 Container

Physical Properties
Composition-Muscovite,Cericite, chlorite,hematite, kaolinite, micas, quartz,clay and other accessory minerals (wide variation in composition).
Hardness-Soft - easily scratched. They can also be as hard and dense as granite
Absorption-Low - medium oil, water other liquids
Weathering characteristics-Due to the wide ranges of slate, this stone has wide ranges of weathering. Cleft planes provides permeability for water penetration resulting in spalling and flaking. Slates that have a high kaolinite content (a clay) display accelerated rate of deterioration in wet environments
Tendencies-Absorbs oils and liquids...Softer/medium varieties scratches easily.
Colors-Colors vary widely
Finish-Different finishes such as acrylic, wax, natural cleft, honed etc.

Kota Blue Limestone

Kota Blue Limestone

Kota Blue Limestone have gained much popularity because of its fine shade of bluish green that adds liveliness to the surrounding. This stone is preferred for flooring and wall cladding, paving and facades of buildings. It is mainly because Kota Blue has the unique properties of limestones. This kota blue stone is very tough, non water-absorbent, non-slip, non-porous and have excellent stain removability. Kota blue stones are available in variety of finishes in different forms such as tiles, slabs, cobbles and block. Kota blue limestone tiles and blocks can be cut to any size as per the requirement of the clients. Edges are honed to avoid possible damages during transportation or application at the site.

Place of Origin : Kota Physical Properties Physically, Limestone are Quite impervious, Hard, Compact, fine to very fine grained calcareous rocks of sedimentary nature.
Hardness -3 to 4 on Moh''s Scale
Density -2.5 to 2.65 Kg/m3
Compressive Strength-1800 to 2100 Kg/cm2
Water Absorption -Less than 1%
Porosity -Quite low
Weather Impact -Resistant

Chemical Properties Chemically, both limestone and marbles are siliceous calcium carbonate rocks.
Lime (CaO) -38-42%
Silica (SiO2) -20-25%
Alumina (Al2O3) -2-4%
Other Oxides like Na, Mg -1.5 to 2.5%
Loss On Ignition (LOI) -30-32%

Limestone, like marble and other calcareous stones, are referred to as acid sensitive. Calcareous stones are readily dissolved in acid, therefore acidic products should not be used on limestone and marbles.
