Dave Daniel AKA (Bones) Posted December 20, 2008 Share Posted December 20, 2008 First timer, use a dental pick and a lot of time and patience. v = 0.25 * g0.5 * SL1.67 * h-1.17 Link to comment Share on other sites More sharing options...
ebrocklds Posted December 20, 2008 Share Posted December 20, 2008 if you have one, an air scribe is much faster, but also easier to damage the fish. with a littel practice you can get a 6 inch fish done in an hour or two. i just finished this one about 20 minutes ago. i used an air scribe and air abrasive to get the job done. this on is a nice little Priscacara liops Brock Link to comment Share on other sites More sharing options...

Auspex Posted December 22, 2008 Share Posted December 22, 2008 The process is called "scratch-and-blow"; good light and a pair of magnifier "goggles" will help. Take your time and enjoy it; haste won't help a bit! The final clean-up can be done by rubbing with an art gum eraser.

ebrocklds Posted December 22, 2008 Share Posted December 22, 2008 using the scratch and blow technique will take time. hours to days depending on the size of the fish. be persistent and it will come out even better than the one i posted.

Cole20200 Posted January 11, 2009 Share Posted January 11, 2009 Have you every experimented with solvents? I've got a little dremel stylus, but it feels a little too strong to be delicate with it. Does anyone else have any experience with the Dremel stylus? Fossil, it's like a rock, but better. Link to comment Share on other sites More sharing options...
Guest solius symbiosus Posted January 11, 2009 Share Posted January 11, 2009 ^^They are best used for removing excess material as the rotating bit will damage the fossil. A small engraver then can be used to remove the remaining matrix if you don't have a scribe. Link to comment Share on other sites More sharing options...
