Description: Madras Silk Granite is a medium grey-brown granite with multicoloured veining. This stone internationally may be nominated as a granite however in the area of application of the European Standard we are awaiting clarification. The veining and colour varies considerably and a small sample of Madras Silk 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. Madras Silk granite is suitable for both interior and exterior use futhermore is frost resistant and with a constant polish.
Note: Madras Silk granite is extremely hard and requires considerable processing time.
Products: Suitable for construction projects both commercial and domestic, prefabricated countertops/worktops, vanities, tiles, backsplashes, paving, fireplaces and memorials.
Surface Finish: Madras Silk 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 probable that a sealant can be used on Madras Silk granite however excessive attempts at sealing it could actually create a residue film build-up.
Block Sizes: This is a quarry yielding yielding several, selectable, grades of granite with blocks suitable for gangsaw size down to economical tile-sized and monument blocks. Extraction commenced in 2012. 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: Madras Silk granite is quarried in India. There is only one quarry of Madras Silk and the veining and colour varies considerably, a small sample is not representative of the whole slab.
Granite: Granite is a common and widely occurring type of intrusive, felsic, igneous rock. Granites are usually medium to coarse grained, occasionally with some individual crystals larger than the groundmass forming a rock known as porphyry. Granites can be pink to dark gray or even black, depending on their chemistry and mineralogy.
