docdutronc Posted December 8, 2008 Share Posted December 8, 2008 Yes front and back, the coal film is hiding a very fell preserved side I've been considering removing it... any ideas?P.S. It really must be good if you think it is superb. I think you should not removed the film coal is inportant to explain to people that the film is the bark of the plant and that the grey mold is the internal medular cast ,so you must find a solution to preserve the coal ....

The coal is actually quite stable, it won't go anywhere without the use of power tools. Link to comment Share on other sites More sharing options...
Guest solius symbiosus Posted December 8, 2008 Share Posted December 8, 2008 I spent many hours with an engraver trying to removed a layer of coal from a nice Lepidodendron that I found; it was only marginally successful. Link to comment Share on other sites More sharing options...
Guest Nicholas Posted December 8, 2008 Share Posted December 8, 2008 I spent many hours with an engraver trying to removed a layer of coal from a nice Lepidodendron that I found; it was only marginally successful. I did the same with another sample of mine, It turned out well because the fossil was first ironized then carbonized so it left a nice orange color which defined the small fossil well.

Guest solius symbiosus Posted December 8, 2008 Share Posted December 8, 2008 I guess mine came out ok(shows very nice detail), but there were still small pieces of the coal attached. This was years ago, and I researched everything trying to find a way to remove the remaining coal(even consulting a PhD Coal Geologist)... to no luck. I finally concluded that I would have to spray the piece with a mist of water and freeze, then repeat multiple times. Link to comment Share on other sites More sharing options...

It almost impossible to remove. The one I did isn't perfect but it it presents well for just a fragment. Link to comment Share on other sites More sharing options...
Guest solius symbiosus Posted December 8, 2008 Share Posted December 8, 2008 Yeah, I don't think there is a chemical that will dissolve coal, but not silica. Link to comment Share on other sites More sharing options...

Just pitch it into the fireplace Actually, baking it in a fast oven might de-link some of the carbon.
