What Conder said! They would never give out their secrets to conservation.
I'm sure NCS uses more than just solvent soaks. As a chemist, I can make educated guesses at some of the processes they use. It's a topic I've put a lot of thought into. Some possibilities:
- bubbling specific gases like hydrogen or carbon dioxide over the coin
- applying controlled heat with inert gas purging
- good old carbon powder, heating and boiling
I wish I had the time and equipment to experiment with some of the techniques I suspect they use.
