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.
Shotgunner: They are promising 94 today!

Fossilman: Scott,do you have a greenhouse or what?? Or just warm enough temps in the winter months..Can't beat fresh spuds!!!

drocknut: I like fresh spuds too. Hard to grow anything in a travel trailer though. Yikes, 94 is way too hot. They are talking close to 90 here at my mom's so I may be hiding in the ac for a while.

mr.mohs: yep- the southwest got ripped off this season-- High pressure everywhere... was thinking of going to anthem...but it to hot for the trek. no a.c. & the freeze plug is weak...

drocknut: Does not bode well for the summer ed
Mar 28, 2015 11:37:17 GMT -5
mr.mohs: it would seem that way. Diane. BUT I recall one unseasonably warm spring and yet we had a mild summer. the last couple summers have been mild --although this last summer -- lasted all winter & spring UUUGHH! Maybe in for brutal one...

Fossilman: Helping Tammy can grapefruit today...................Juice and fruit...LOL,she loves it,I hate the stuff..

drocknut: I hope it's not a brutal one Ed.

snowmom: fossilman, I'm with Tammy. that's good stuff! Grapefruit juice is my favorite drink.

drocknut: I don't care for grapefruit juice, too bitter for me even with a lot of sugar added.
Mar 29, 2015 16:43:28 GMT -5
Fossilman: I couldn't drink it even if I did like it-bad reaction with my meds and grapefruit juice...
Mar 29, 2015 17:14:26 GMT -5
drocknut: I understand that, grapefruit juice does not mix well with lots of meds.

lparker: It does mix well with Black Velvet

Shotgunner: Mike, winter is the season to grow potatos in SoCal. Lettuce greens too. Tomatoes are a perennial here. Plant once and harvest for years. Just cut back the plants at the end of winter for new growth in spring.

Fossilman: Damn,that's the way to grow Scott........................

mr.mohs: grapefruit & Black Velvet! now that's good medicine

mr.mohs: right on Mike! bypass the grapefruit juice --straight to the hard stuff. at this age whatever doesn't kill us makes us stronger...mostly
