Black Galaxy Granite Problems
Black galaxy granite is one of the most prominent granite found in India. It is an expert's choice for making kitchen countertops and floorings. This stone is very popular worldwide because of its luster and shine. It is found in the State of Andhra Pradesh where its quarries are located. Rough blocks, slabs, tiles, and countertops of this stone are exported from India to the world. Though this stone is highly demanded there are many problems associated with this granite. However our clients are very interested to know black galaxy granite problems, so here we are explaining some of the major black galaxy granite problems to clear the doubts.
We will discuss some of the main problems relating to the nature of black galaxy granite
Black lines– on the surface of the stone sometimes we see black lines. It is not necessary that every stone has a black line but these days it is hard to blocs without this black line. Further, there can be multiple black lines in one bloc or single slabs. It is the nature of this material. These black lines can be vertical and horizontal. Also, they vary in thickness. There can a small pencil line or a very thick line or medium line on the stone. On average, almost 20-30% of the slabs processed from high-quality galaxy blocs have these lines. It is rare to find a bloc without any black line.

White lines– In addition to black line black galaxy stone can also white lines on its surface. As with black lines, these white lines can also be more than one and multi-directional. The white line is considered to be a very big issue then black line because it ruins the look of the stone. So the stone with white lines is of commercial and low quality. As such they are not suitable for export and mostly use in domestic markets.
Cracks– Cracks can occur in the stone due to many reasons. First due to poor processing of the stone. Second due to faulty blocks. Third due to mishandling by labors and lastly due to bad packing and transportation issues. If the crack is in a corner then it can be trimmed but if the crack is in the center then nothing can be done about it.


Mergeable lines– Mergeable lines are usually not visible on the stone's surface and can only be noticed during a closer inspection. Compared to white or black lines, they are considered minor issues because they do not disturb the overall color or pattern of the stone. The photo shown here features premium Black Galaxy Granite.

So far, we have discussed all the major issues found in Black Galaxy Granite. It is rare to find a block that is completely free from these problems. For this reason, clean slabs are far more expensive than others because of their limited availability. If a flaw appears near the corner, it can often be trimmed, but if it lies in the center of the slab, it cannot be corrected. There is also variation in blocks from one quarry to another. In general, high-quality slabs show consistent galaxy patterns, color, and overall appearance.
Conclusion
