phillipdmatthews Posted May 16, 2019 Share Posted May 16, 2019 (edited) Hello to Everyone... I'm hoping that someone might be able to advise me about preventing oxidation on a pyritized ammonite. I have no doubt that this question has cropped up before and wondered of anyone had some good advice. I'm reluctant to immerse it in acetone (Seems a tad aggressive?) I know that polishing it will only be a temporary fix. So... Two questions - what can I use to polish it back to a shiny finish and... Two... I do have some clear, low viscosity, pure silicon oil - I use it to fill vintage compasses that I restore. Does anyone know if this would react with the FeS2 in an adverse way? Sadly my knowledge of chemistry is very lacking. :-( I'd love to hear your thoughts...
