As mentioned, Golden Black stone is processed and supplied in the form of tiles and slabs. The dimensions of the processed slabs are different and are determined according to the size of the stone. The approximate dimensions of the slab are 140 to 190 cm in width and 220 to 290 cm in length. In tile processing, stones are processed in widths of 40 cm, 60 cm and 70 cm. The thickness of the cut in export varieties is exactly 2 cm, and the thickness for domestic use is between 17 and 18 mm. It is worth noting that Golden Black marble is mainly processed within 40 cm. In some orders, the demand for the width of 60 cm is relatively high, which is very limited and impossible to process due to the limitation in production using the peak cutting method. Therefore, slabs are used for purposes such as cabinet tops and islands, which are mainly 60 cm wide, and the desired sizes are cut from the slabs.
Negative points and weaknesses of Golden Black marble stone:
Golden Black marble reacts to moisture, direct sunlight, cold and heat due to its calcareous properties and the high content of this element in the stone structure. For this reason, it is not recommended to use this stone in the outer space of the building as well as the spaces that are exposed to moisture. For example, this stone becomes scaly due to humidity, and white scales can be seen on its surface.
Also, this stone loses its polished surface and becomes opaque in the sunlight. The reaction of Golden Black marble to extreme cold and heat is that the fossils and burns on the surface of the stone are destroyed and the stone becomes empty.
