## Description

This polish is 99.9% pure 0.3 micron aluminum oxide. It is "AAA" grade, the best you can get, and is known to some under the old brand name 'Linde A.' Linde A is used for polishing tourmaline, beryl, garnet, topaz, peridot, danburite, etc. It has a hardness of Mohs 9, and is therefore most useful for polishing very hard and/or difficult materials (but not corundum, as corundum is also of a hardness 9). ...... For use with faceting machines, sanding belts, lap disks, polishing heads for dremels. Leather or felt polishing tools are preferred, but cotton buffers will work well also.
