## Description

Product Description          The National Geographic Rock Tumbler Supplies pack includes all the rock tumbling accessories you need to dramatically improve your rock polishing results! Pack Includes: 4 Stages of Silicon Carbide Polishing Grit Compound, 1.5 Pounds of Ceramic Media, 30 g GemFoam, 10 mL Scoop and Instructions. Our 4-stage bulk rock tumbling grit is high-quality silicon carbide, perfect for polishing rough rocks into smooth gemstones. The first rock tumbler grit stage provides initial shaping, the second smooths rock surfaces, the third pre-polishes rocks, and the fourth provides the final polish. We include a 10 mL grit scoop so you can get precise measurements for every stage. Grit comes packaged in secure, screw-top containers for easy storage. And when you add our ceramic tumbling pellets to the mix, you will see even better results! Ceramic media helps to more effectively distribute grit to rock surfaces during tumbling, reduces tumbler noise, serves as filler for smaller batches, and reduces rock breakage through every grit cycle. One of the most exciting elements of this tumbling accessories pack is our new patent-pending GemFoam. This tumbling media was specially designed to add dazzling shine to polished stones. Simply add GemFoam, water, and rocks to the tumbler barrel and in a few days your stones will have a high-quality polish. Instructions inside the kit detail how to use all the tumbling media for optimal results. This pack is compatible with all rock tumblers, but for best results use with National Geographic rock tumblers and tumbling accessories.
