I have freeze-dried both hefty Chinese lacquer, as well as thinner coatings
which appeared to have had no ground layers. These were all waterlogged
archaeological artifacts which had been pre-treated with PEG 200 and 400.
Everything was problematic, and the trouble started in the pre-freezing for
36 hours before the drying started, so it wasn't caused by only pulling the
vacuum on these materials. The thicker layers would crack in spots, and the
thinner lacquers could curl at the edges (think charred, wispy newspaper).
This anecdotal information may not be too much help to you, but I thought it
was worth posting. I would be more concerned about what the coating(s) are,
since the chariot is from the 1980's. Are you sure it is urushi? Auto body
lacquer? (no joke...) And any mixture of coatings and substrates could be
problematic, with different moisture contents and expansion/contraction
rates.
I would opt for the anoxic bubble
Good luck! feel free to e mail me back

Why would you want to freeze the lacquer ware? What's the pest?

Subject: [pestlist] freezing Japanese laquer
Does anyone have experience with or an opinion on freezing Japanese lacquer
ware? The object in question is a Japanese festival chariot from the 1980’s,
comprised of a number of different materials, some of which are black
lacquered wood. The composition of the lacquer has not been determined (we
don’t know if it is Urushi or not), but at this point of time it is in very
good condition.
Thanks!
