I have recently begun my journey into fossil prep, i'm using a dremel electric engraver as it seemed to be the best cheap tool. I have several ammonites from Yorkshire within nodules - these are very hard in the centre and consist of pyritised sediment. It is taking a very long time with the dremel using tungsten-carbide point, so just asking for any advice on how is best to try and get through these very hard bits. Cheers in advance!!

Hi all, First off, I am a real noob when it comes to prepping fossils... This is why I have a question for you, which I don't think would be too hard for you pros out there. Some of you may have seen this sea urchin before; anyways I wanted to prep it, as I believe it will look quite nice after a good prep. There is just one problem though: the matrix is very hard (compared to what I'm used to). So how should I clear all this matrix? The tools I have are very limited, but I can buy new things (as long as they are very cheap materials). I have: one long thin metal needle, one strong pointed needle, one strong small chisel, and one thing to blow the matrix away (sorry if I don't have the correct terms)... If needed I can post a picture of the tools. Here is a picture of the fossil:
