Mochaccino Posted August 19, 2022 Share Posted August 19, 2022 Hello, I'm considering picking up this section of Didymoceras cheyennense (I believe living chamber) from the Pierre shale of Pennington county, South Dakota, USA. However I found out that a lacquer layer has been applied to it to accentuate the iridescence. Is this something that can be removed without damaging the ammonite? And would I use something like acetone to remove it? Thank you. Link to comment Share on other sites More sharing options...
Kane Posted August 19, 2022 Share Posted August 19, 2022 I would see if acetone might work. Try a small, inconspicuous spot first to see if it does the trick. 1 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...

RJB Posted August 20, 2022 Share Posted August 20, 2022 Lacquer is an oil based product and did nothing to enhance the color. In fact it very well may have reduced what color it had. Acetone will easily cut the lacquer and should not damage the piece of ammo in anyway unless it is fragile. RB 1 1 Link to comment Share on other sites More sharing options...
Ptychodus04 Posted August 20, 2022 Share Posted August 20, 2022 It looks pretty stable so, the acetone shouldn’t be an issue. Just submerge it and let it sit for a few hours. You should be good to go after that. 2 1 1 Regards, Kris Global Paleo Services, LLC https://globalpaleoservices.com http://instagram.com/globalpaleoservices http://instagram.com/kris.howe Link to comment Share on other sites More sharing options...

So it looks like it'll be fine to try remove after all. Thank you all! Link to comment Share on other sites More sharing options...
