    • The method comprises the steps of inserting the certain amount of volcanic rock in a heating furnace, heating the rock up to the temperature of 600 VC not to be damaged by an sudden expansion from over-heating, raising the heating temperature higher than the fusing point of the volcanic rock of 1,000-1,200 VC, heating continually until the rock is not transformed but the melted surface of the rock becomes lustrous, cooling the rock slowly again and obtaining various colors of volcanic rock by controlling the amount of infusing air corresponding to the fuel in heating the rock, thereby preserving the external shapes or characteristics of the rocks and colors of the natural volcanic rocks, thus being produced in a large scale and applied to the various souvenirs.
    • 该方法包括以下步骤:将一定量的火山岩插入加热炉中,将岩石加热至600℃以上,不会因过热而突然膨胀而损坏,使加热温度高于熔点 的火山岩1000-1200 VC,连续加热直到岩石不变形,但是岩石的熔化表面变得光泽,再次慢慢冷却岩石,并通过控制相应的喷射量来获得各种颜色的火山岩 燃料加热岩石,从而保留天然火山岩的岩石和颜色的外部形状或特征,从而大量生产并应用于各种纪念品。
