Why I Believe National Geographic Rock Tumbler Grit is Necessary

As someone who has been rock tumbling for years, I can confidently say that National Geographic Rock Tumbler Grit is an essential component for achieving beautiful, polished stones. Without proper grit, the tumbling process would be incomplete and the end result would not be as smooth and shiny as desired.

One of the main reasons why National Geographic Rock Tumbler Grit is necessary is because it helps to remove rough edges and imperfections from the rocks. When tumbling, the grit acts as an abrasive agent that wears away at the rough surface of the rocks, revealing their natural beauty underneath. Without grit, this process would take much longer or may not even be possible at all.

Additionally, National Geographic Rock Tumbler Grit comes in different stages (coarse, medium, fine) which are necessary for achieving a polished finish. Each stage plays a crucial role in smoothing out the rocks and preparing them for the next level of grit. Skipping a stage or using inadequate grit can result in an unpolished or uneven finish.

Moreover, National Geographic Rock Tumbler Grit is specifically designed for rock tumbling and has been tested and approved by experts in the field

My Buying Guide on ‘National Geographic Rock Tumbler Grit’

As a proud owner of the National Geographic Rock Tumbler, I have come to realize the importance of using the right grit for achieving desired results. The quality and type of grit used can make a significant difference in the final outcome of your tumbled rocks. Therefore, I have put together this buying guide to help you make an informed decision when purchasing National Geographic Rock Tumbler grit.

What is rock tumbler grit?

Rock tumbler grit is a finely ground abrasive material used in the process of tumbling rocks to achieve a smooth and polished finish. It comes in different levels of coarseness, from coarse to fine, and is made from various minerals such as silicon carbide, aluminum oxide, and cerium oxide.

Factors to consider when buying National Geographic Rock Tumbler Grit:

• Grit Size: The size of grit you use depends on the stage of tumbling you are in. For initial grinding and shaping, use coarse grit (60/90). Medium grit (120/220) is used for smoothing and pre-polishing while fine grit (500/600) is used for polishing.
• Type of Grit: Each type of mineral used in making rock tumbler grit has its unique properties. Silicon carbide is ideal for harder stones like quartz and jasper, while aluminum oxide is better suited for softer stones like obsidian and marble.
• Grit Quantity: The amount of grit you need depends on the size and capacity of your rock tumbler. For best results, follow the manufacturer’s guidelines for recommended amounts.
• Durability: Look for brands that offer durable and long-lasting grit to avoid frequent replacements during the tumbling process.
• Certified by National Geographic: Ensure that the brand you choose is certified by National Geographic as it guarantees quality and effectiveness.

Where can I buy National Geographic Rock Tumbler Grit?

National Geographic Rock Tumbler Grit can be purchased from various online retailers such as Amazon or directly from their official website. It is also available at most hobby or craft stores.

Tips for using National Geographic Rock Tumbler Grit:

• Cleanliness: Make sure your tumbler barrel is clean before adding new rocks and fresh grit to avoid contamination.
• Frequent Checks: Check on your rocks regularly during each stage of tumbling to ensure they are not getting over-tumbled or under-tumbled.
• Patiently Wait for Results: The tumbling process takes time, so be patient and let your tumbler do its job without rushing it.

In conclusion, choosing the right type and quality of National Geographic Rock Tumbler Grit plays a crucial role in achieving beautiful polished rocks. Consider all these factors before making a purchase to ensure successful results with your rock tumbling experience. Happy tumbling!
