how to split boulder opalBoulder Opal is found in the state of Queensland, Australia and is the second most precious type of opal after black opal. The process of mining the rock and then turning it into a polished stone is explained here, how to Split Boulder Opal.

Boulder Opal is formed in Ironstone and in veins of colour bars. This Ironstone can be sandy in composition to deep consolidated dark brown ironstone. Boulder Opal can be found around Yowah, Australia and is more deep brown in colour compared to the sandy ironstone around Winton to Quilpie in Queensland.

This rough boulder opal is also formed in rocks and pancake shaped rocks that need to be split open so that they can be cut and polished into stones. Most opal miners crack open a rock to expose any colour so that they can ask a greater price for the rock. It’s worth noting that not all rocks have colour. It takes a lot of work to mine the rock in the first place and then sometimes miners can crack open a rock with a hammer and find no colour. It can sometimes be a game of luck for the miners. Once colour is found the miner will ‘slab’ the opal bearing rock.

 

 

 

How to Split Boulder Opal

  1. Make sure you wear safety glasses while chipping and sawing Rough Opal at all times.
  2. After slabbing the rock the best method when you get to a color bar is to take to thin saw blade and place small cut along the colour bar.
  3. Most times this will crack open and the next morning it will show a clean split.
  4. If the rock does not split take a hammer and a screw drive or a blunt edge and hit along the saw cut and the rock will split open exposing the colour bar.

如何分割巨石蛋白石博尔德蛋白石是在澳大利亚昆士兰州发现的,是继黑芝士之后第二种最珍贵的蛋白石。在这里解释了开采岩石然后将其变成抛光石头的过程,如何拆分博尔德蛋白石。

博尔德蛋白石是在铁矿石和彩色条纹中形成的。这种铁矿石可以成为深层固结的深棕色铁矿砂。澳大利亚Yowah附近可以找到巨石蛋白石,与昆士兰州Winton到Quilpie周围的砂质铁矿相比,它的颜色更深棕色。

分裂巨石蛋白石

这种粗糙的巨石蛋白石也是在岩石和薄饼状岩石中形成的,需要将它们分开,以便它们可以被切割和抛光成石头。大多数蛋白石矿工都会打开岩石露出任何颜色,这样他们就可以为岩石付出更高的代价。值得注意的是,并非所有的岩石都有颜色。首先挖掘岩石需要大量的工作,然后有时矿工可以用锤子打开岩石并找不到颜色。它有时可以成为矿工的运气游戏。一旦发现颜色,矿工将“踩踏”蛋白石轴承岩石。

如何拆分巨石蛋白石

  1. 确保您在切削和锯切粗蛋白石的同时戴上安全眼镜。
  2. 在铺设岩石之后,当你到达一个颜色条时,最好的方法是采取薄锯片并沿着颜色条放置小切口。
  3. 大多数情况下,这将打开,第二天早上它将显示一个干净的分裂。
  4. 如果岩石不分裂,则采用锤子和螺旋驱动器或钝边缘并沿锯切割并且岩石将分开以露出颜色条。
