Description: Bros Blue Granite is a fine-grained, blue-grey gneiss of the Precambrian period with striking light blue veining and sometimes with small red garnets plus grey and/or light to dark blue heavy veining extremely common. 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 gneiss. The veining and colour varies considerably and a small sample of Bros Blue 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. Bros Blue 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: Bros Blue 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. We never use colour enhancers.
Sealing: Test with a small sample. It is possible that a sealant can be used on Bros Blue however excessive attempts at sealing it could actually create a residue film build-up.
Block Sizes: This is an exclusive, medium-sized granite quarry yielding selectable, grades of granite with blocks suitable for gangsaw size down to economical tile-sized and monument blocks. Extraction commenced in the early 1990s. 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: Bros Blue granite is from our own sheet bedrock quarry near Andhra Pradesh, India.

Gneiss: A common and widely distributed type of rock formed by high-grade regional metamorphic processes from pre-existing formations that were originally either igneous or sedimentary rocks. Gneissic rocks are usually medium to coarse-foliated and largely recrystallized but do not carry large quantities of micas, chlorite or other platy minerals. Gneisses that are metamorphosed igneous rocks or their equivalent are termed granite gneisses, diorite gneisses, etc.
