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.

rockpickerforever: Supposed to get cold and windy here, couple inches of rain forecast for the weekend, and then some. Even the desert is supposed to get liquid sunshine. We need it, but why can't it rain during the week? So much the for the rock field trip this weekend.

rockpickerforever: Fossilman, making a nice hot batch of the Jalapeno jelly today, yum!! Can't get enough of that stuff! Might go out and use the stove in the trailer, so I'm not breathing chile pepper fumes all day, lol.

rockpickerforever: Oh, I should mention... Cold here is maybe down into the 40s. Not that below freezing or below 0 type of insanity. Who can live in such a place that has those temps? And all that white stuff, uggghhhh!

drocknut: Chili pepper fumes, one way to clear out the sinuses..lol. I can handle the cold (btw 40 doesn't count as cold yet) but that hot stuff you call jelly geez how can you eat that...lol.

rockpickerforever: Diane, it's not the sinuses, the fumes make you gag and your throat burn. Trying to be considerate of poor, sick Lucy. Diane, you just don't know what you're missin. And yes, considering what it costs to live here, 40 degrees IS damn cold, lol.

Feb 27, 2015 10:14:32 GMT -5
rockpickerforever: Fossilman, that jalapeno jelly came out smokin' hot, the hottest batch yet. Close to being too hot, maybe?? The jalapenos give it that great flavor, add about ten Hot Black Cobra chilies for heat. Need to eat it with something to avoid stomach ulcers.

rockpickerforever: The rain is a'coming. Supposed to get cold, windy and wet tonight, and stay that way until Tuesday. Yep, field trip to Himalaya Mine on Saturday has been postponed... edmohs, okay to sing, mostly, but stay out of the rain! Grind 'em, baby, grind 'em!
