Black Galaxy Granite

Indian Black Granite

Description

Black Galaxy Granite is a fine to medium-grained, black gabbro of the Precambrian period with golden-yellow sparkling broncite scales. 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 gabbro. 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. Black Galaxy 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

Black Galaxy 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.

Sealing

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.

Quarry Location

Black Galaxy granite is from our own sheet bedrock quarry Cheemakurti, Bodawada, Prakasam District, Andhra Pradesh, Southern India. There are approximately 50 Black Galaxy granite quarries and all vary in graining, flecking size and notably background colour. For projects do not mix Black Galaxy from different quarry sources since it will most likely be very obvious!

Gabbro

A dark-coloured, coarse-grained intrusive igneous rock. Gabbro is very similar to basalt in its mineral make up. It is composed mostly of the mineral plagioclase feldspar with smaller amounts of pyroxene and olivine. Gabbros are found widely on the Earth and on the Moon as well.

Quarry Blocks

There are about 50 Black Galaxy granite quarries. Extraction at the original Black Galaxy granite quarry commenced in the very early 1980s. The quarries vary hugely in size and production levels, granite blocks suitable for gangsaw size down to economical tile-sized and monument blocks are usually readily available however for commercial projects it is important to ensure that blocks are selected from the same quarry face, we must repeat, DO NOT try and match-up with alternative Black Galaxy 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.
