I have recently found two ammonites with clear suture markings. After prepping I tried using beeswax to polish and protect on a small part of one of them. This obscures the suture marks somewhat. What would you recommend to protect/polish the ammonites with and to keep the markings clear.

Thanks in advance

Hello, firstly, unless the ammonite is preserved as Pyrite, it won't need "preserving"! All carbonate minerals (as far as I know, but I'm not much of a mineralogist) are stable. You can use a soft toothbrush to remove the excess wax, but assuming you have prepped it with an air pen / air abrader, the best thing to do is use wet & dry paper (wet) of 1000 going down to 1600 as you feel appropriate and then use a polishing powder. Any residue of this in the sutures will be removed when you wash it using a soft tooth brush. Once dry all you will ever have to do then is to dust it occasionally!
You could also use a 5% (wt / vol) solution of Paraloid in Acetone. Add more coats if you want it shinier.
I hope this helps

Many thanks for the prompt and complete reply. I should have said that the fossils are preserved as pyrite. They were found at Tidmoor point. I didn't have to do much prepping and that which was done was done with hand tools. I only tried the wax on a small area so should be easy to remove.

Would this material Paraloid B72 acrylic resin?(found on Amazon) be appropriate?
