Apologies in advance if this is the wrong forum to be asking this! A neighbor of mine put a bunch of stuff on her curb to anyone wanting to take it. I picked up a few really pretty glazed and painted flower pots. 2 of them are smaller and are both stuck to the saucers. I believe they came this way. Can anyone tell me if there's anyway to "unstick" them? i.e. loosen whatever adhesive it is safely, without harming the pot or making them inadequate to grow food or flowers in? I've already checked for labels or stickers explaining what kind of material I am dealing with and have had no luck. Any input is appreciated. Thanks so much!
