Re - Collodion: What is it good for?



 At a previous place of employment, I used to collect and analyze environmental
 samples. For samples of vegetation and soil, we used to grind up the material
 in a mill, ash it in a furnace, then cover it with collodian to keep the ash
 from blowing off in our lab's gas flow proportional counters.
