First Yorkshire Ammonite Prep Advice Please


Recommended Posts

Calli99

So this is the first prep I've attempted with my new Dremel (with specialised tips for fossils/rocks). The ammonite is from Saltwick Bay in Yorkshire. I chose this as my first practice piece as I thought that it was going to be pretty bashed up inside so would be a good one to say 'oh well' if/when I make mistakes. Sadly I now think it could have been quite nice had I saved it for when I have more experience!

 

Anyway, to my inexperienced touch the matrix felt very sticky, with practically none of the matrix popping off nicely. I felt like I was having to carve out the ammonite and there are several spots where you can see I got it wrong and really messed up. My question is, do you think I should go any further? I think the centre may just be present and there are still bits of matrix clinging to some of the ribs but I don't want to do anymore damage and it's too hard to get off with a pin vice (I tried). If you have any advice on prepping matrix like this and any good techniques particularly with ammonites I would really appreciate it.

Forgot to add, this is actually a double with another ammonite on the backIMG_0604.thumb.jpeg.0ddae454ef52ace33b0b3aa0a2c4ea26.jpeg
