I found this point on the surface of a shell midden. We sometimes soak coral or chert (NON POROUS) in light mineral oil for hours to days in order to see the "original" color of the material. I do not like to do this and don't do it often. Acetone takes the oil back off/out. Here is a Columbia Point (PinCo) that I soaked and you can see the changes over time.

We have collectors down here that have backlit/oil filled caseboxes of filthy coral points..... Some people use ketchup and other goops on river points that actually take off the "last" layer of water/wet site patina. Flint River stuff.Professor Shellman
