Different Surface Finishing of Granite Mongolia Black?


The popular surface finish of mongolian balck is polished,honed, flamed, bush-hammered, and sandblasted.

Polish is the best way to show the solid colour, the surface is smooth, it can be used for flooring, wall cladding, skirting, countertops, headstones, etc.

Honed surface, also called matt finish, give people another feeling of elegance, the stone colour becomes grey, the surface is smooth, too, but not as shiny as polish. Australia customers like this finish so much, it has a little anti-slip function, usually used for bathroom flooring, sometimes for countertops (benchtops).


Flamed is the second most popular processing method. Some clients call it heating or burning. After flaming, the stone surface becomes rough, it is very helpful for anti-slip, popularly used for outdoor flooring,swimming coping,stairs and steps, etc. The thickness should be over 1.5cm for flamed finishing because the stone becomes fragile under extremely high temperature, easy to be broken, thinner the stone is, more breakage will be.

After flamed, we will brush the stone surface one or two times, to make it be friendly to our naked hand touching and remove the rust dirt. If it is brushed by over 5 times, the surface will become ,pre smooth, we call it leather finishing because it is touched like the leather, this surface processing is usually used for bathroom flooring and tabletops.



Bush-Hammered is another surface treatment for the anti-slip function, after bush-hammered, the stone surface will be full of shallow and small holes, same as the flamed finishing, this processing is widely used for outdoor flooring and steps. Because the stone will be under the very high-pressure impact, it has a higher requirement for the thickness, it should be 2.5cm up.


Sandblasted is similar to bush-hammered, but its holes are much smaller and the quantity is larger, its touch feeling is more comfortable, because of the different processing procedure, the stone with under 2.5cm thickness can be sandblasted, too. These surface treatment products can be used for bathroom flooring.

How to identify the quality of Mongolian Black Granite?


Firstly,the surface structure of Mongolian black granite is observed by naked eyes. Generally speaking, the stone with uniform fine material structure has a fine texture, which is the best stone; the appearance effect of the stone with coarse-grained and unequal grain structure is poor. Besides, due to the influence of the geological process, stone often produces some minor cracks, which are most likely to crack along these parts, so it should be removed. As for the lack of edges and corners, which affects the beauty, we should pay special attention on it when choosing.


Second, measure the size and specification of the stone to avoid affecting the splicing, or causing the deformation of the pattern, pattern, and line after splicing and affecting the decoration effect. (for this point, Mongolian black stone generally does not have the problem of poor design and color.)

Third, listen, that is, listen to the sound of stone percussion. Generally speaking, the knocking sound of good quality stone is crisp and pleasant; on the contrary, if there is a slight crack in the stone or the contact between particles becomes loose due to weathering, the knocking sound is coarse and dumb.

The last tips is testing, which is to use a simple test method to test the quality of the stone. Generally, a small particle of ink is dripped on the back of the stone. If the ink is quickly dispersed and leached around, it means that the particles inside the stone are loose or there is a gap, and the quality of the stone is not good; otherwise, if the ink drips in place, it means that the quality of the stone is good.
