Use for Azurite, Jade, Malachite, Lapis Lazuli, Rhodonite for a gorgeous finish. Gives a wet look to agate. .... Powdered.... Much easier to work with than sticks ... Chrome Oxide will shine stainless steel and is an excellent polish for knife makers. Mix with corn cob in a tumbler to polish brass casings .... just use a half teaspoon full at a time and run the tumbler till the corn cob is coated, adding a tiny bit at a time. ....... For rock polishing, use with faceting machines, sanding belts, lap disks, polishing heads for dremels, or can be used by hand (with a lot of effort). Leather or felt polishing tools are preferred, but cotton buffers will work well also..... Chrome Oxide can be very messy.
