## Description

Rock Tumbler Polish - 12000 Grit Aluminum Oxide for Final Finish, Step 5 Polishing Grit for Rocks, Gems, Glass & Jewelry Making - Ultra-Premium Refill, 1 Lb: desertcart.com: Industrial & Scientific

Review: Work - Works great
Review: Consider this the fifth step - Normal rock polishing is done in four stages, but I found that with this one and more polish, the rocks came out quite a bit shinier. Very happy with the results.

## Features

- KomeStone's best-selling rock tumblers offer something for everyone: the K1 and K1 Pro (2.5 lb capacity, with the Pro featuring a brushless motor), the K2 (3 lb capacity with a noise-reducing cover), and the K4 (dual barrel, 7 lb capacity, brushless motor, and noise-reducing cover). Perfect for both beginners and experienced rock collectors.
- We offer 8000 and 12000 grit polishing powders, designed for the final stages of tumbling. Unlike grinding powders, which are used in Steps 1-4 to round the stones, our polishing powders are ideal for achieving a high-gloss finish starting from Step 5. You can choose either grit based on your desired shine, offering flexibility to tailor the polishing process for optimal results.
- Designed for Professional-Grade Final Polishing: KomeStone 12000 Grit Aluminum Oxide Polishing Powder is perfect for achieving a high-gloss, mirror-like finish. It’s engineered for the final step in stone, gem, and glass polishing, eliminating fine scratches and enhancing surface clarity.
- Suitable for a Wide Range of Materials: Whether you’re working with gemstones, quartz, agate, glass, or other hard surfaces, this polishing powder is versatile and reliable. Use it for both hobby and professional projects to bring out the best in your materials.c
- Polish Any Stone or Gem with Ease: Whether you're working with rocks, gemstones, or minerals, this powder is versatile enough to handle all materials, enhancing their natural beauty and shine.
- Easy Application – Recommended Usage: Mix 2 tablespoon of powder with water to create a smooth paste. Use it in a rotary or vibratory tumbler for 3–5 days, adjusting the polishing time and powder quantity based on the hardness and size of your material. Always ensure the tumbler is running smoothly for optimal results.
- Achieve Professional Results with the Right Equipment: Our 12000-grit polishing powder works best with a professional polishing machine. While it can be used in a rotary tumbler, results may not meet expectations. If you're unfamiliar with polishing powders or equipment, we recommend learning more before ordering. If you're experienced and still wish to proceed, please consider carefully before purchasing.
