20200906_092510.jpg  5198.jpgGood morning - I recently found this Liparoceras at Seatown, also with negative imprint of a 2nd ammonite.  I haven't soaked it as didn't want to dissolve the clay matrix in the centre, and was planning to coat with paraloid once completely dry but have noticed (as shown in the close up) that there is some reddening occurring on the shell. Is this oxidation? Should I be worried by this and will it spread if left untreated ? All assistance gratefully received! Please excuse what is probably a basic question but really just trying to build up my knowledge of how to best preserve my finds.

Why would you not want to remove the clay?

Because I suppose I would quite like to keep the imprint on top in situ - which it might not do if I soak.

It doesnt really need much cleaning, just wash it gently with a soft brush and a little water, dont let the clay get too wet.

That's great,  thanks very much Gary 👍. Is the red tinge just a consequence of it coming into contact with the air ?

I cannot see the red, but probably just part of the preservation, nothing to worry about as it does not look pyritic.
