What are the preferred tools for polishing?

Leather or felt polishing tools.

Can I use this in the rock tumbler as a 5th stage to make rocks smooth and shiny?

No, this product is not recommended for rock tumbling. It is intended for other polishing purposes.

Will this product work to remove scratches from sunglasses?

It is uncertain whether this product will effectively remove scratches from sunglasses. It is advisable to test it on a less expensive item before using it on expensive sunglasses.

This product is in powder form, which could be used to make a paste if desired.

Can I mix this product, Linde A, with tin oxide for cabbing turquoise?

No, it is not recommended to mix abrasive powders. Aluminum oxide is harder than tin oxide, so they should be used separately.

Fundamental Rockhound Products: 1 oz .3 Micron Aluminum Oxide Linde A - Lapidary Rock Polish

Linde A Aluminum Oxide Polishing Powder is a very fine polish powder used for various purposes. Customers have used it for polishing marble, opals, jade, and fine optical pieces. Some customers have used it for polishing rough stones, but it is not a coarse polish. It is suggested that customers should test it on a piece of plastic or glass before using it on an expensive item. The powder can be used for knife stropping, but it is 0.5-micron particle size, so a fine edge is needed. Overall, customers have found this product to work very effectively for their needs. It is recommended by users with some preferring it over products like diamond paste and sapphire powder.

Pros

Provides a great shine on stones such as Petoskey, opals and jade.
Effective for fine polishing before polish optics and prism lens.

High grade aluminum oxide makes it effective for knife stropping.

Cons

Not suitable for coarse polishing.
