Air Scribe of a Brachiopod

Over the weekend I got a chance to use an air scribe for the first time. My intent was to clean a blastoid that was recently given to me. I will post my initial work on this soon. After realizing that it takes quite a bit of time to fully clean a fossil so I picked up this brachiopod to clean one side real fast.

This first picture is of the side of Ordovician brachiopod found east of Louisville, Kentucky that was not cleaned.

Here is the picture of the other side that has been cleaned.
