LakeErieLady Posted December 22, 2015 Share Posted December 22, 2015 I find a lot of these black rocks with crinoid sections on them. Locally they are called "Starry Night" stones. When they are wet the are beautiful, and the crinoids segments stand out in stunning detail. But when the rocks are dry, they are dull and easy to overlook. Is there a way to prepare them so the detail shows? Link to comment Share on other sites More sharing options...
Auspex Posted December 22, 2015 Share Posted December 22, 2015 Try beeswax. If that does not do it, it can be removed and you can try a clear spray lacquer (not easily reversed). They are quite beautiful wet!

Fossil Claw Posted December 22, 2015 Share Posted December 22, 2015 Believe it or not, try pledge floor wax with future shine. Straight for a wet look and diluted for a little shine. It can easily be removed with hot water and a tooth brush Link to comment Share on other sites More sharing options...
PaleoRon Posted December 22, 2015 Share Posted December 22, 2015 Those stones are soft enough to polish with wet/dry sand paper if you want them permanently shiny. Start with something like a 200 grit then go to a finer grit until you are happy with the degree of polish. Warm beeswax would be quicker though. If you have pounds of them to polish you might want to get a cheap tumbler. Link to comment Share on other sites More sharing options...
RJB Posted December 22, 2015 Share Posted December 22, 2015 I like Paleorons tumbler idea, but it is time consuming. Good luck RB Link to comment Share on other sites More sharing options...
amour 25 Posted December 23, 2015 Share Posted December 23, 2015 Yep Harbor freight tumbler or a Hobby Lobby one, don't think a brass one would work as no water. Jeff Link to comment Share on other sites More sharing options...
ZiggieCie Posted December 23, 2015 Share Posted December 23, 2015 I was thinking tumbler also. Home depot has them very reasonable to polish them up, if the other ideas aren't what you want. Link to comment Share on other sites More sharing options...
