Granite Exporter Of Essentials + Exotics
Ultimate Black Granite is a very dark black, extremely fine to close-grained black basalt with equi-granular crystalline texture quarried near Mysore, Karnataka, India. This stone internationally may be nominated as a granite but in the area of application of the European Standard this stone must be nominated as a basalt. 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. Ultimate Black granite is suitable for both interior and exterior use futhermore is frost resistant and with a constant polish.
As a generalisation all black granite quarries have varying shades of black. This variation in shading is completely natural and usually occurs with the ground level of the quarry being lighter with the deeper the granite is quarried becoming darker, however some quarries may vary in shade along its length or width. The experienced quarryman knows where the lighter and darker shades are and can supply to the customer's preferences. All of our Indian black granites are from the Deccan Plateau.
NOTE: It is a fact that some unscrupulous dealers will actually dye the lighter shades and try to sell them as the Ultimate Black, Premium Black or Absolute Black product at its correspondingly higher price, with totally normal usage these "doctored" blacks will lose their artificially applied darkness. To check for dying try the lemon juice or acetone test. Do ensure that the granite is washed clean before doing this otherwise it may simply be general dirt. Take a clean white rag and apply some lemon juice or acetone to the granite surface. If any residue or black appears on the rag then it has been dyed. Also, if you have several small sample choices, leave a drop of the lemon juice for five minutes on the polished surface, wipe the surface clean and observe the results, once again any dull spot or patch and the material has been doctored.
Needless to say we never use colour enhancers.
Suitable for construction projects both commercial and domestic, prefabricated countertops/worktops, vanities, tiles, backsplashes, paving, fireplaces and memorials.
Ultimate Black granite looks best with a gloss polished surface but is also available as honed, leather/satin, river-washed/antique, thermal/flamed, flamed & brushed, water-jet, bush-hammered, sandblast and sawn finish.
Test with a small sample. It is most unlikely that a sealant can be used on this granite due to the very tight grain formation, attempts at sealing it could actually create a residue film build-up.

An extrusive igneous (volcanic) rock that is low in silica content, dark in colour, and comparatively rich in iron and magnesium. Some basalts are quite glassy (tachylytes), and many are very fine-grained and compact. It is more usual, however, for them to exhibit porphyritic structure, with larger crystals (phenocrysts) of olivine, augite, or feldspar in a finely crystalline matrix (groundmass). Olivine and augite are the most common porphyritic minerals in basalts; porphyritic plagioclase feldspars are also found. Basaltic lavas are frequently spongy or pumiceous; the steam cavities become filled with secondary minerals such as calcite, chlorite, and zeolites.
Basalts may be broadly classified on a chemical and petrographic basis into two main groups: the tholeiitic and the alkali basalts. Tholeiitic basaltic lavas are characterized by calcic plagioclase with augite, pigeonite or hypersthene, and olivine (rarely) as the dominant mafic minerals; basalts without olivine are also well represented. Tholeiitic basalts, which contain 45 to 63 percent silica, are rich in iron and include the tholeiites (basalts with calcium-poor pyroxene).
These are quarries yielding yielding several, selectable, grades of granite with blocks suitable for gangsaw size down to economical tile-sized and monument blocks. Extraction is believed to have commenced in the 1980s. For commercial projects it is important to ensure that blocks are selected from the same quarry face, do not try and match-up with alternative black granite sources.
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.
