I have a pendant (labradorite set in silver plated piece) that I wanted to redo the stone and set somehing different in the metal. So I figured it may have been set using a super glue so I broke out the acetone and set the piece in there for about 5 hrs or so. Low and behold the stone soaked up the acetone completely. The liquid turned purple and was completely gone. Reason why I know the stone soaked it up is that I would pick it up from time to time to see if the stone loosened. The last time I did it the liquid went under the stone then gone. How should I go about this now? Fill my bowl up even more with acetone and see if it comes loose or try something different? Thanks in advance.

Acetone does evaporate rapidly when left uncovered. I soak my stuff in a glass dish loosely covered and still need to add acetone every day. I have had some take over a week and still had to pry them apart.

Buy the nail polish remover that is all acetone. It will be advertised for acrylic nails. That stuff is generally 100%.
I agree with Chuck. Acetone evaporates even faster than alcohol, I think. Put it in a little glass jar with a lid.

Yeah I had first gotten some that was acetone free (never used it cause I think girls had it for their nails). I got some walgreens or Walmart brand last time. Just want more so I don't use a bottle each time...

When I have something like this I soak in acetone and brush away the excess loose epoxy. After the piece has dried out I hold the metal over an alcohol lamp and gently heat it a bit and tap it on a hard surface. Epoxy has a low melting point so it will loosen easily without much heat. I remove pearls from earrings or rings this way, but I only use a low flame and only apply it to the metal. Proceed slowly with a low heat. Make sure there isn't any puddles or rags soaked in acetone nearby the open flame! Bob

Boiling is 212f only half way there.
Bake in the toaster oven.

I soak my stuff in white vinegar. Will check out the acetone idea. Dollar store carries acetone, though the hardware or paint shoes might be cheaper if you do a lot of this.

You don't have to heat it much, just enough to soften the epoxy. Bob

On a similar note: I use superglue for dopping and switched to gorilla glue gel, similar to superglue to get better adhesion. Of the 6 cabs I dopped; two snapped off after a few hours in the freezer, two more snapped off after being soaked for 1/2 hour in acetone and the last two required some help with a box cutter. I thought I might be using too much so I used less and three cabs came off the dop sticks. I'm back to using the same amount of glue before and crossing my fingers.

I used to use acetone, but now I use the flame from a butane torch. They come off in seconds. I use nails as dops.
