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.

wampidy: pickup before I go running around in the hills. One of my goodest tires has a bulge and all the tread is worn off of it in that spot. Tells me that I probably should have replaced it a long time ago but it is just a little wup wup.

snowmom: LOL, I did ask.. I'll be more careful next time! I expect hounding out there is a terror on tires- all those sharp rocks...

rockpickerforever: Diane, if he said he was sitting in his underwear, most would understand that he is not naked. What's wrong with naked, anyway? ...Unless that's your laptop sitting in his lap, ho ho!

wampidy: There was not one of the tires on my pickup good enough to replace my raggedy spare. Just went ahead and bought all four. As bad as the front tires were it is a wonder I am not laying in a ditch somewhere between here and Quartzsite.

wampidy: Sure drives nice now except for the wandering. Replaced the steering ball joints before I left for Q and they already have a bunch of slop in them. Must have been a tad bit of stress there on the trip.

Fossilman: New tires are always a blessing...

snowmom: we just got new tires too.. must be the season... or maybe the places we go? Yes,a blessing... the difference is amazing, and the car actually stays on the road in the rain now...

Stone Whisper: Fossil.. New Tires maybe on the way.. but first I have to get these new shocks ready.. The eye/loops were not coated very well, Thus I was forced to repaint. Besides I best get down there now and put the last set of bushings in them.

rockpickerforever: New tires on my F250 in May, caught a large staple in one Monday, they had to replace it . But only cost me $30 for a new certificate. Too bad the weights keep coming off, and I have to keep getting them rebalanced - three times already!!!
