Description: Pradesh Green granite is a fine-grained, grey-green gneiss of the Precambrian period with white and white-grey banding. This stone internationally may be nominated as a granite and in the area of application of the European Standard this stone must be nominated as a gneiss. The veining and colour varies considerably and a small sample of Pradesh Green granite 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. Pradesh Green Granite is suitable for both interior and exterior use futhermore is frost resistant and with a constant polish.
Products: Suitable for construction projects both commercial and domestic, prefabricated countertops/worktops, vanities, tiles, backsplashes, paving, fireplaces and memorials.
Surface Finish: Pradesh Green Granite 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 Pradesh Green granite however excessive attempts at sealing it could actually create a residue film build-up.
Block Sizes: This is a quarry yielding selectable, grades of granite 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: Pradesh Green granite is quarried in the Kuppam region, East Ghats, Andhra Pradesh, Western and Eastern Ghats, India
Synonyms: Green Multicolour, Kuppam, Kuppam Green, Kuppan Green, Maharani, Multi Colour Green, Multicolor Green, Multicolor Groen, Multicolor Gruen, Multicolor Verde, Multicolor Vert, Pradesh Green, Verde India, Verde Marina, Verdi Marina
Gneiss: A high grade metamorphic rock. Gneiss is medium to coarse-grained and may contain abundant quartz and feldspar, which some petrographers regard as essential components. The banding is usually due to the presence of differing proportions of minerals in the various bands; dark and light bands may alternate because of the separation of mafic (dark) and felsic (light) minerals. Banding can also be caused by differing grain sizes of the same minerals. The mineralogy of a particular gneiss is a result of the complex interaction of original rock composition, pressure and temperature of metamorphism, and the addition or loss of components.
