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.
