Description

Product Overview

Polly Plastics brings a professional‑grade solution for the final polishing phase of rock tumbling. This 1200‑grit aluminum oxide media is engineered to provide a mirror‑like shine on a wide variety of stones, gemstones, and other tumbling materials. Each package contains two 1‑lb jars, offering a total of 2 lb of fine abrasive that is perfect for hobbyists and small‑scale manufacturers alike. The media is manufactured in the United States using high‑purity aluminum oxide, ensuring consistent particle size and minimal contamination. With a compact 6 × 6 × 1.5‑inch container, the product is easy to store, transport, and integrate into any tumbling workflow.

Usage

This media is designed for use in any standard rock tumbler, including popular models from Elenco, Lortone, National Geographic, Smithsonian, and Thumler. Simply add the media to the tumbler barrel after the coarse and medium grinding stages, and run the tumbler for the recommended final‑polish cycle, typically 7‑10 days depending on stone size and desired finish. The fine 1200 grit works exceptionally well for polishing quartz, agate, jasper, and other semi‑precious stones, as well as for smoothing metal parts and creating a high‑gloss surface on custom jewelry components. Because the media is non‑reactive and free of contaminants, it is safe for use with delicate or porous materials that could be damaged by harsher abrasives.

FAQ

What size stones can I polish with this media?

The 1200‑grit aluminum oxide is ideal for stones ranging from 1 mm up to 10 mm. Smaller stones achieve a brilliant shine quickly, while larger stones may require a longer polishing cycle to reach the same level of brilliance.

How often should I replace the media?

Because the media is reusable, you can often reuse it for several polishing cycles as long as it remains free of debris and clumps. If the media becomes discolored or clumped, it is best to replace it to maintain optimal polishing results.

Is this media safe for use with metal jewelry pieces?

Yes, the non‑reactive aluminum oxide is safe for polishing most metals, including copper, brass, and silver. It will not cause chemical reactions or surface damage when used as directed.

Can I use this media for polishing glass or ceramics?

The fine grit works well on glass and ceramic surfaces, providing a smooth, glossy finish. However, always test a small sample first to ensure the desired outcome, as some ceramics may require different polishing parameters.

What is the recommended tumbling time for the final polish?

Typical final‑polish cycles range from 7 to 10 days, depending on stone hardness and size. Monitor the progress periodically and adjust the time as needed to achieve the desired shine.
