Imperial Gold Granite Image

Description: Imperial Gold granite is a yellow, grey gneiss with some single red-brown garnets, often with veining and some ore, 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 gneiss. 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. Imperial Gold 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: Imperial Gold 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 Imperial Gold however excessive attempts at sealing it could actually create a residue film build-up.

Block Sizes: This is a 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: Imperial Gold granite is quarried near Tippu, Chennai, Tamil Nadu, India. There are several different quarries of Imperial Gold Granite all varying in shade and veining.

Synonyms: Gold Imperial, Oro Imperiale

Gneiss: A high grade metamorphic rock. Gneiss is medium to coarse-grained and may contain abundant quartz and feldspar, which some petrographers regard as essential components. The banding is usually due to the presence of differing proportions of minerals in the various bands; dark and light bands may alternate because of the separation of mafic (dark) and felsic (light) minerals. Banding can also be caused by differing grain sizes of the same minerals. The mineralogy of a particular gneiss is a result of the complex interaction of original rock composition, pressure and temperature of metamorphism, and the addition or loss of components.
