Use this high-grade micro-alumina polishing compound on your pads, buffs, flat laps, sphere machines, or wherever a fine polish finish is needed. These high grade polishing aluminas have been custom developed for the Lapidary Industry, use as you would cerium or tin oxides. To use this polish, make a nice slurry by mixing the polish with either water, mineral oil (like Roc-Oil) or a 50-50 oil and dishwashing detergent mixture.
Poly-AL-T is a medium fine powder with 0.8 micron particles and generally polishes better than Tin Oxide. Particularly effective on hard stones and is an ideal pre-polish on softer stones as it does not undercut.
Poly-AL-F is the finest of the Poly-AL polishes with a particle size of only 0.2 microns. This polish will put a superior polish on most any stone that has been properly prepared for polish. Does not break down much during use so you consume less polish during use.
