As you know,there are so many kinds of stone in the world,Such us : Granite, Marble, Limestone, Slate, Quartzite, Sandstone, , Onyx, etc.
In fact, granite water absorb rate is low, generally( 0.15% ~ 0.46%)Granite density, high hardness, the surface is very wear-resisting, a certain extent reduce the chances of the stain . Many experiment proved that in all used in outdoor ground material, White Granite Stone is the best ability to resist bacteria regeneration.
Marble has been valued for thousands of years for its rich palette of beautiful colors and appearance. It is perfect for use in almost any part of the house. Generally, calcite and Chinese Grey Marble Tiles are of pure white color. Variations of whiteness of pure marbles are due to the mixture of foreign substances. Such impurities form bands, streaks and clouds. Black and grayish shades are due to graphite; pinks, reds are mainly due to the presence of manganese oxides or hematite.
A great combination of earth tone colors and the finish makes this stone one of a kind. The vibrant colors and unique textures make slates appropriate for interior as well as exterior applications. Because it is formed in layers, it can easily be split to expose beautifully textured surfaces. The usual colors of slates are earthy (various shades and mixes of browns, beiges, yellows), black, dark-grays, and greenish-gray but shades of pinks, purples and copper are also found. They usually exhibit a lot of variation in color among the pieces quarried from the same site. Slates, depending on their individual hardness, are used for flooring, cladding and landscaping.
China Pure White Quartzite Stone Slabs are very similar to slates, but with a higher content of Quartz, which gives them, a sparkling texture. They are so close in appearance to slates that usually they are referred to as quartzitic-slates. Just like slates, they are used for various applications depending on their hardness.
As the name suggests, Sandstone is made of sand cemented by silica, iron, lime etc. The color of sandstone depends on the cementing material; ferruginous (iron) sandstones are reddish, brownish; carbonaceous, black; siliceous, white and argillaceous, earthy to buff. Other than the hardness, the porosity of the sandstone is also a key factor in deciding the suitability for its applications.
The muted tones of limestone are perfect for today’s more casual and comfortable lifestyles. Generally these soft beiges and tans, either polished or honed, are appropriate for bathrooms, fireplaces, counters and less-traveled flooring, where a more informal decor is desired. Limestone’s are sedimentary rocks that are formed at the bottom of lakes and seas as silt and organic matter settle to the bottom. A more and more layers build up over thousands and millions of years, adding more and more weight, the heat and pressure cause chemical reactions to take place and harden the sediments into solid stone.
