My Buying Guide on ‘National Geographic Rock Tumbler’
As an avid collector of rocks and gemstones, I have always been fascinated by the process of tumbling rough stones into smooth and shiny gems. That’s why when I came across the National Geographic Rock Tumbler, I knew I had to add it to my collection. After using it for a few months, I can confidently say that it is one of the best rock tumblers in the market. In this buying guide, I will share my personal experience and insights on purchasing the National Geographic Rock Tumbler.
What is a rock tumbler?
A rock tumbler is a machine that uses abrasives and water to polish rough stones into smooth and shiny gems. It works by rotating a barrel filled with rocks, grit, and water for several weeks, mimicking the natural process of erosion. The end result is beautiful polished stones that can be used for various purposes such as jewelry making or home decor.
Why choose the National Geographic Rock Tumbler?
I chose the National Geographic Rock Tumbler mainly because of its brand reputation and quality. National Geographic is a trusted name when it comes to educational and scientific products, so I knew their rock tumbler would be reliable and efficient. Plus, their tumbler comes with a learning guide that teaches about different types of rocks and how to identify them.
What’s included in the kit?
The National Geographic Rock Tumbler kit comes with everything you need to get started – a large barrel (2lb capacity), four types of grit (coarse, medium, fine, polish), nine types of rough gemstones, jewelry fastenings, instructions booklet, and educational guide. This means you can start tumbling rocks right out of the box without having to purchase any additional supplies.
The tumbling process
The tumbling process with this machine is fairly simple and straightforward. First, you need to add your rough stones into the barrel along with some water and coarse grit. Then let it tumble for 7 days before replacing the coarse grit with medium grit for another 7 days. After that comes fine grit for 7 days followed by polish for 7 days. The whole process takes about a month but the end result is well worth it.
Noise level
I was pleasantly surprised by how quiet this rock tumbler is compared to others in the market. It has rubber lining on both ends of the barrel which helps reduce noise while in use. This was important for me as I live in an apartment building where noise can be an issue.
Durability
The National Geographic Rock Tumbler is made with high-quality materials that are built to last. The motor is powerful enough to handle large batches of rocks without overheating or breaking down easily. In addition, its sturdy design ensures that it can withstand regular use without any issues.
Cleaning & maintenance
Cleaning and maintaining this rock tumbler is relatively easy. After each step in the tumbling process (coarse grit/medium grit/fine grit/polish), you will need to clean out any debris from inside the barrel before adding new materials. You also need to rinse off your polished stones after each step before adding them back into the barrel.
Conclusion
In conclusion, if you are looking for a reliable and efficient rock tumbler that produces high-quality polished stones, then I highly recommend the National Geographic Rock Tumbler kit. With its educational guide included in the kit, it’s not only a fun activity but also a great way to learn about different types of rocks and geology.
Happy tumbling!
