Cafe Bahia Granite Image

Description: Cafe Bahia granite is a medium to coarse-grained syenite with a pink-brown background and grey-blue grain of the Precambrian period. 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 syenite. The veining and colour varies and a small sample of Cafe Bahia 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. Cafe Bahia 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: Cafe Bahia 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 Cafe Bahia 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: Cafe Bahia granite is quarried at quarry RN 000034, Fazenda Araunas, Riacho de Santana, Bahia, Brazil.

Synonyms: Bahia Coffee, Brown Caffee, Brown Coffee, Cafe Bahia-Marron, Cafe Brown, Caffe Bahia, New Imperial Brown

Syenite: A coarse-grained intrusive igneous rock of the same general composition as granite but with the quartz either absent or present in relatively small amounts (<5%). The feldspar component of syenite is predominantly alkaline in character (usually orthoclase). Plagioclase feldspars may be present in small quantities, less than 10%.

Mineral Composition: Average by % Orthoclase: 65%, Aegirinaugite: 12%, Quartz: 10%, Plagioclase: 5%, Biotite: 5%, Hornblende: 3%.
