I have an urgent request! I found this beautiful coral today (my very first of this type!) in ice cold water. It was stable and not flaking when I picked it up. After a couple hours of drying at room temperature, it's become extremely brittle and is falling apart. I've placed it in cold, filtered water, and placed it in the refrigerator hoping to stabilize it until I can find out how to possibly treat it. Is what I've done the right thing? I have no idea what the matrix is, I suspect a type of shale, maybe limestone but can't handle it at all right now. Thank you! Sorry about the bad photos, I'm freaking out and was in a hurry
