Has anyone figured out a way to polish calcite? I know its soft but there must be a way. I gathered up some nice pink ornamental stone used to put around shrubs, etc. I put it through the Vibe with AO with no shine results. I run the polish cycle again with TO and still no results. I cushioned pretty well with ceramic and soap but it just didn't take a shine. Has any one been able to shine the stuff?

Calcite and the tumbler are not friends! Basically you end up with a calcite slurry! And polishing works pretty good with calcite. I tried cabbing some but pretty much failed as the calcite was just too soft for my heavy handed ways.
I can't tell if thats some Gneiss Schist, or that Schist is Gneiss. All I know is don't take it for Granite

Here's why it doesn't work in a tumbler, from wikipedia: "Calcite can be either dissolved by groundwater or precipitated by groundwater, depending on several factors including the water temperature, pH, and dissolved ion concentrations. Although calcite is fairly insoluble in cold water, acidity can cause dissolution of calcite and release of carbon dioxide gas. Calcite exhibits an unusual characteristic called retrograde solubility in which it becomes less soluble in water as the temperature increases. When conditions are right for precipitation, calcite forms mineral coatings that cement the existing rock grains together or it can fill fractures."
Some rocks aspire to greatness; others are destined to be grit carriers.

tweaking the pH to prevent it dissolving is a very neat idea. I have a dim memory of something similar for cleaning iron off of calcite crystals without dissolving them. But I think soft still presents a problem.
