Polishing Rhodochrosite

When cutting Rhodochrosite only use water in the saw. Oil will be absorbed and the color dulled. After the material is ground to form, sand first on 220 grit (wet) and then on 400 (wet). Use worn sanding cloths. Tin oxide is the best polishing agent—some use tin oxide mixed with a little vinegar and used on felt. Another method is to mix two teaspoons of tin oxide and one level teaspoon oxalic acid in a half pint of water. Be careful not to exceed the amount on oxalic acid or the stone will be damaged.
