The Lava in our location is a kind of basalt with about 10 percent gas holes. It is hard and gray. As a kind of ideal decorative material, it makes the square, the tourist attraction, or the courtyard simple and unsophisticated, serious and solemn. It also can absorb the sound and dust indoor. The site of BOAO Forum Asian and the 53rd world miss final are widely decorated by the lava. we aslo can make the lava into stone table, stone chair, stone door, stone lamp and stone mill. They are very useful and interesting. The magma was brought to the surface of the earth when the volcano erupts, without the pressure; it cools quickly and form many gas holes. According as gas hole, the lava is divided into tiny hole lava, small hole lava and middle hole lava.. The tiny gas holes,less than a millimeter, are regular, on the contrary. The smaller gas holes, about 3-10 millimeter, are irregular, and like honeycomb. The middle gas holes are about 8-15 millimeter. So it is also called honeycomb stone. |
