Why I Believe National Geographic Rock Tumbler Grit is a Necessity
As a passionate rock collector and hobbyist, I have tried various methods of polishing and tumbling rocks to achieve their beautiful, smooth finish. However, it wasn’t until I started using National Geographic Rock Tumbler Grit that I truly saw the difference in my results. From my personal experience, here are a few reasons why I believe this grit is necessary for any rock tumbling enthusiast.
First and foremost, National Geographic Rock Tumbler Grit is specifically designed for tumbling rocks. This means that it has the perfect balance of abrasiveness and hardness to effectively polish rocks without damaging them. Using other types of grit or even sand can result in scratches or uneven surfaces on your rocks, ruining all your hard work.
Moreover, this grit comes in different stages – coarse, medium, fine, and polish – which are essential for achieving a smooth finish on your rocks. Each stage gradually reduces the roughness of the surface until it reaches its final polished state. Trying to skip or substitute these stages with other materials may result in an incomplete or subpar polish.
Another important factor is the quality of the grit itself. National Geographic takes pride in sourcing high-quality
My Buying Guide on National Geographic Rock Tumbler Grit
As a rock collector and hobbyist, I have been using the National Geographic Rock Tumbler for quite some time now. One of the essential components of this tumbler is the grit that is used to polish the rocks. In this buying guide, I will share my personal experience and recommendations on purchasing the right grit for your National Geographic Rock Tumbler.
What is Grit?
Grit is a substance made up of finely ground particles and is used in the tumbling process to smooth and polish rocks. It comes in different levels of coarseness, from rough to fine, and each level contributes to achieving a shiny, polished surface on your rocks.
Factors to Consider
Before purchasing National Geographic Rock Tumbler Grit, there are a few factors you should keep in mind:
1. Tumbler Capacity: The first thing you need to consider is your tumbler’s capacity. The larger the tumbler, the more grit it will require.
2. Type of Rocks: The type of rocks you want to polish also plays a significant role in choosing the right grit. Harder rocks like agate or jasper require grit with a higher level of coarseness compared to softer stones like obsidian or limestone.
3. Grit Sizes: As mentioned earlier, grit comes in different sizes ranging from coarse (60/90) to fine (800/1000). Each level has its specific purpose in the tumbling process.
Types of Grit
There are various types of grit available in the market, but here are the three most commonly used types for rock tumbling:
1. Silicon Carbide Grit: This type of grit is highly recommended for use with National Geographic Rock Tumblers as it produces fast and efficient results. It comes in four levels – 60/90 coarse, 150/220 medium, 500 fine, and 1200 pre-polish.
2. Aluminum Oxide Grit: This type is ideal for polishing softer stones as it produces less friction during tumbling. It comes in four levels – 120/220 coarse, 400 medium, 600 fine, and polish.
3. Cerium Oxide Polish: This type of polish is used as a final step after using aluminum oxide or silicon carbide grits. It gives an extra shine and smoothness to your rocks.
Where to Buy?
National Geographic Rock Tumbling Grit can be easily found online at various retailers such as Amazon or directly from their official website. You can also find them at local hobby stores or rock shops.
Final Thoughts
In my experience, I have found that using silicon carbide grit works best with my National Geographic Rock Tumbler for achieving excellent results within a short period. However, it’s always essential to keep experimenting with different types and sizes of grit until you find what works best for you.
I hope this buying guide has provided you with valuable insights into choosing the right grit for your National Geographic Rock Tumbler so that you can enjoy tumbling beautiful polished rocks for years to come!
