Granite is a coarse-grained intrusive igneous rock that composes of quartz, feldspar, and plagioclase. The granites give aesthetic characteristics to the building and have become one of the preferred choices in the construction industry. There are numerous granite options available in the market; however, the Black Galaxy Granite stands out due to its sophisticated looks and vast range of benefits. Here we take a look at what Black Galaxy Granite is, its properties, applications, and everything you need to know.
What is Black Galaxy Granite?
Black Galaxy Granite is a natural black granite stone composed of Notire/Gabbro rock. It is known for its luxurious and glossy black surface with golden bronzite specks, mimicking a galaxy effect. This granite is primarily originated from Andhra Pradesh, India, and has been used since the early 1980s. It became widely popular for itscontemporary, distinctive, fashionable appearance and extraordinary physical properties. The durable properties make the granite withstand varied weather conditions, both when applied indoors and outdoors.
Characteristics of Black Galaxy Granite
Colour
The Black Galaxy Granite is predominantly black, with metallic gold or white/silver specks.
Size
This granite is used both as a slab and tile, and its sizes vary accordingly. The nominal size of the Black Granite Slab is around 120” x 70” (305 cm x 180 cm). The standard sizes of the Black Galaxy Granite Tiles are (12” x 12”), (18” x 18”), and (24” x 24”).
Appearance
The black background with golden and silver specks gives an attractive galaxy look. The surface appearance of the granite is glossy (polished), matte (honed), and textured (leathered) finish.
Density
Black Galaxy Granite is packed tight and has high density. The density of this granite typically ranges from 2.95 to 3.07 g/cm³.
Hardness
The Black Galaxy Granite is hard, as it measures 6.5 to 7 on the Mohs scale. This makes it one of the hardest natural stones, as it can resist almost all kinds of scratches, chips, and cracks.
Compressive & Flexural Strength
The Black Galaxy Granite has high compressive and flexural strength. It has a compressive strength of 290-320 MPa (Mega Pascals) and a flexural strength of 20-25 MPa (Mega Pascals). The high strength helps the granite to withstand loads.
Porosity & Water Absorption
The Black Galaxy Granite is dense, tightly packed, and has very low pore gaps. This results in a low water absorption rate of 0.05% to 0.2%.
Grades of Black Galaxy Granite
The Black Galaxy Granites are classified into four grades depending on the flecks, lines, size, and distribution. Following is the detailed breakthrough of the different grades of black galaxy granite.
Premium & Premium+ Grades
The Black Galaxy Granite of Premium & Premium+ grades have larger and evenly distributed flecks, few to no veins and unmatched clarity and uniformity. This grade of granite is known as “popcorn galaxy” and is suitable for high-end projects.
Semi-Premium
The semi-premium Black Galaxy Granite is slightly lower grade than the premium. It has small, invisible black veins; however, after polishing, it becomes unnoticeable. This grade of granite is a popular choice for a clear finish.
Standard Quality
The Black Galaxy Granite of Standard Quality grade has one or two visible black lines, and the fleck distribution has slight variations. This grade of granite is used for vast applications. They are suitable for kitchen countertops, flooring, and wall cladding.
Commercial Quality
This grade of granite has multiple lines and non-uniform fleckings. However, it is affordable without compromising the visual appeal. The Black Galaxy Granite of this grade is suitable for large commercial projects.
