How to choose a quality stone?
Inevitably, you will need to decorate with stones, and choosing stones is certainly a challenge for the novice decorator. Buying marbles, floor tiles and other stones can easily meet the challenge of stone selection by capturing the following four steps.

In general, uniform fine-grained stone has a fine texture, which is a stone product; coarse-grained unequal-grained stone has a bad appearance, uneven mechanical and mechanical properties, and somewhat poor quality. In addition, due to the geological role of natural stone, often produce some fine texture, microfissures, these stones are easy to break along these parts, should be removed. As for the lack of edges and corners, it is more beautiful, especially when choosing.
Volume II: the size of the stone, so as not to affect the splicing, or cause splicing pattern, pattern, line deformation, affecting the decorative effect.
Third: listen to the sound of the stone. Generally speaking, good quality, dense interior, no microscopic cracks in the stone crisp and pleasing; on the contrary, if there are microscopic cracks or fine veins inside the stone, or due to weathering caused by loose particles, please knock the sound hoarse.
Four tests: Use simple tests to check the quality of the stone. Typically, a small drop of ink is placed on the back of the stone. If the ink spreads and oozes out quickly, it means that the stone has loose internal grains or microscopic cracks. The stone is of poor quality. Conversely, if the ink drop does not move in its original position, it means the stone has a dense texture.
