ˇˇˇˇVesuvianite<br>The vesuvianite, which abounds in the southern part of China, is a kind of multi-gas-hole basalt. With its peculiar quality of being hard, gray color, and polish-free, it is an ideal outdoor decorative material suitable for such places as square, scenic spot and courtyard, etc, which creates a sense of suppleness and gravity. Besides, this material can also be used for special purposes indoors such as absorbing sound and dust. <br>Magma is brought to the surface of the earth when a volcano erupts. Free from the underground pressure, it cools down quickly and forms many gas holes( with a percentage of about 10%). The tiny holes(smaller than 1mm) have even distribution, while the bigger holes (about 5-10mm) are unevenly distributive like a honeycomb, thus the vesuvianite is also called honeycomb stone<br><br><br>Email:stone@hainan-stone.com[]
