Amber is the polymerized form of copal, a liquid produced mainly by tropical conifers such Agathis and dacrydium. In 1930, copal production was near 30 000 metric ton/year and was used in the vernish industry, today it has been displaced from that use by oil derived products and there is no more copal industry. One possibility to use copal was to freeze dry for a short time, giving a some months conservation and then putting copal in place of water as long term conservator and protection against the britle state of dryed objects. Chineses have discovered some embalmed corpses immersed in a copal-like resin with fresh looking face after many century. I don't know about microstructure conservation but from data on amber I assume it must be good. If you think reversible cryonics state can be produced in the comming fifty years, LN2 is better, if it is longer, room temperature conservation such copal looks better. I have tested for four years now the Agathis production in souther France and I have a field to start next year a large cultivation effort with 10 000 trees. Yvan Bozzonetti.
