Description: Rainforest Brown Marble, a.k.a. Bidasar Brown Marble, is a light brown, heavily-veined Serpentinite with dark brown veins. This stone internationally may be nominated as a marble but in the area of application of the European Standard this stone must be nominated as Serpentinite. The veining and colour varies considerably and a small sample of Rainforest Brown Marble may not be representative of the whole slab therefore swatch samples must be approved for large projects to ensure that the blocks are all extracted from the same quarry face for matching purposes. During the polishing process a clear epoxy resin filler may be used to fill any micro fissures or tiny pitting however this does not affect the integrity of the stone, it merely provides an even smoother surface finish. Rainforest Brown Marble is ideal for both interior and exterior use however polish is only constant inside.
Products: Suitable for construction projects both commercial and domestic, prefabricated countertops/worktops, vanities, tiles, backsplashes, paving, fireplaces and memorials.
Surface Finish: Rainforest Brown Marble looks best with a gloss polished surface but is also available as honed, leather/satin, river-washed/antique, thermal/flamed, brushed and sandblast finish.
Sealing: Test with a small sample. It is possible that a sealant can be used on Rainforest Brown however excessive attempts at sealing it could actually create a residue film build-up.
Block Sizes: This is a quarry yielding selectable, grades of marble with blocks suitable for gangsaw size down to economical tile-sized blocks. For commercial projects it is important to ensure that blocks are selected from the same quarry face.
Rough blocks are usually exported by Break Bulk however intermodal containerisation is available at extra cost. Finished products are packed into sea-worthy wooden crates and loaded into containers.
Quarry Location: Rainforest Brown Marble is quarried near Bidasar, Rajasthan, India. There are several different quarries of Rainforest Brown Marble all varying in shade and veining.

Marble: Is a metamorphosed limestone, composed of very pure calcium carbonate, CaCO3. The softness of marble and its relative isotropy and homogeneity make marble very desirable for sculpture and building stone. Although marble comes from limestone, the temperatures and pressures necessary to form marble usually destroy any fossils that may have been present in the limestone.
Marble derives its name from the Greek marmaros, shining stone. [source: OED2]. This stem is also the basis for the English word marmoreal meaning "marble-like". In folklore, marble is associated with the astrological sign of Gemini. Pure white marble is an emblem of purity. It is also an emblem of immortality, and an ensurer of success in education.
Serpentine: Any of a group of hydrous magnesium-rich silicate minerals. The composition of these common rock-forming minerals approximates Mg3Si2O5(OH)4. Serpentinite is a rock composed of one or more serpentine group minerals. Minerals in this group are formed by serpentinization, a hydration and metamorphic transformation of ultramafic rock from the Earth's mantle.
