Use this pre-polishing compound in rock tumblers, flat laps, sphere machines or wherever a good pre-polish finish is needed. To use this pre-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. Aluminum Oxide Pre-Polish is used as a pre-polish on soft and difficult to polish stones such as Apache tears and tigereye. Can also be used as a final polish on extremely hard materials (+8 on MOH scale.) Great for slabs. 800 grit. Packaged in durable, reusable plastic containers to prevent damage during shipping and provide for easy storage. Doesn't sound quite right for your needs?
