2ynpigo Posted April 23, 2014 Share Posted April 23, 2014 A fossil may be coated with a colored substance to enhance contrast between the fossil and its matrix. How do you as collectors feel about this practice if is done only to improve contrast, and not to hide reconstruction or completely faked parts?

fossilized6s Posted April 23, 2014 Share Posted April 23, 2014 Personally i don't mind if it's a dull preservation but is full of detail. Highlighting growth segments in Ammonites is always cool looking. ~Charlie~ "There are those that look at things the way they are, and ask why.....i dream of things that never were, and ask why not?" ~RFK ->Get your Mosasaur print ->How to spot a fake Trilobite ->How to identify a CONCRETION from a DINOSAUR EGG Link to comment Share on other sites More sharing options...
Uncle Siphuncle Posted April 23, 2014 Share Posted April 23, 2014 I occasionally apply a layer of beeswax cut thin with turpentine to certain ammonites and echinoids to impart depth and richness of color without a manufactured looking glossy sheen.

fossilcrazy Posted April 23, 2014 Share Posted April 23, 2014 Watered down Dextrine will increase a subtle contrast. Removable by washing in water if it is found objectionable by you or the next owner. Link to comment Share on other sites More sharing options...
steedman Posted April 23, 2014 Share Posted April 23, 2014 I often use dilute pva; it really helps scales and fins to stand out from the matrix. Works for me! Link to comment Share on other sites More sharing options...
jpc Posted April 23, 2014 Share Posted April 23, 2014 I am a purist... no coatings unless they help hold the thing together. Link to comment Share on other sites More sharing options...
MarqusandDad Posted April 24, 2014 Share Posted April 24, 2014 For educational or display pieces I can see using a coating to not only bring out the details but to help protect the fossil. Link to comment Share on other sites More sharing options...

erose Posted April 25, 2014 Share Posted April 25, 2014 I like mine naked. Link to comment Share on other sites More sharing options...
Taogan Posted April 25, 2014 Share Posted April 25, 2014 Naked is better, we don't know enough about long term damage that could be caused by coating a fossil. It might make it look better for me but what about for my great grandchildren. Link to comment Share on other sites More sharing options...
