Description: Cambrian Black granite is a medium-grained, black gabbro 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 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. Cambrian Black 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: Cambrian Black 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 unlikely that a sealant can be used on Cambrian Black granite and 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: Cambrian Black granite is quarried near Saint-Nazaire, Quebec, Canada.
Synonyms: Cambrian, Cold Spring Black, Royal Black.
Gabbro: Any of several medium or coarse-grained intrusive igneous rocks that consist primarily of plagioclase feldspar and pyroxene. Essentially, gabbro is the intrusive (plutonic) equivalent of basalt, but whereas basalt is often remarkably homogeneous in mineralogy and composition, gabbros are exceedingly variable. Gabbros are found widely on the Earth and on the Moon as well.
