China Black is the most famous stone species in Hebei Province, and also the largest stone production (different from basalt Mongolian Black, Fuding Black and other low hardness stone species). The hardness is high, and its Mohs hardness is 7. If you use ordinary knives, you can't print marks. The density is large (2.9-3.2). The weight of a cubic meter of net stone is about 3 tons. Knocking with hard objects will produce sounds similar to metal. The structure is a fine granular companion crystal structure, so its strength is relatively large, strong resistance to nature (light, water immersion, thermal expansion and cold shrinkage, natural environment acid-base, weathering, etc.). So there is a thousand years of existence. In fact, its natural life is more than that. For mirror polishing, the luminosity can be above 100 degrees. So there are also black mirrors.
Its processing energy products are mainly table panels, indoor and outdoor surfaces, walls, large plots of paving stones, tombstones, handicraft blocks, measuring platform and so on.
