[Rockhounds] mineral trades

[Glenn Wimpee]

Hi Dave,
 
You can preserve the shine by coating the marcasite.
 
I have had some success with lacquer.
 
There are probably better coatings if you do not mind this preservation method.
 
I've cleaned some with vinegar and even muriatic acid, but if left unprotected they oxidize pretty soon.
 
We have a good many nodules in the Selma Chalk Formation that runs through the Black Belt of Alabama.
 
This formation is also abundantly loaded with sea fossils.
