Re: Plaster of Paris and Epoxy Resin????
Personally I would not want something like that encased in epoxy. To protect it you could construct a padded box that holds it in place, maybe set down into a fitted recess lined with leather or fabric, held in place with some small decorative tabs, with a secured glass cover on top when you want it on display. Insert a piece of fabric covered foam between the glass top and the item when you want maximum protection.
