Perhaps one should consider Parylene as a coating and preservation material. Parylene was demonstrated by the Getty some years ago at one of the AIC meetings. It formed a thin, invisible, pore-free coating that could preserve things like feathers and brittle paper, and impart them some strength for handling. I believe that they showed a Parylene-coated butterfly wing, and the coating was strong and invisible. Reversibility was a problem... On the other hand, maybe one could eventually replace the tobacco leaves?? Size of chambers for coating could also be a problem--usually Parylene is used for small items. There are a number of Web sites about Parylene, and it is currently used for things like coating medical devices and printed circuit boards for use in extreme conditions.
