[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!

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.

Re: [pestlist] freezing Japanese laquer
I agree with Lou Sorkin argon would be best, but most anoxic users do not use argon. Argon is much heavier than air and can be introduced low in the chamber, driving out the air at the top. It is totally inert.

This is a message from the Pest Management Database List. To post to this list send it as an email to pestlist@museumpests.net To unsubscribe please look at the footer of this email. ---Louis, I understand that argon has some small advantage over nitrogen, notably that it is heavier and can be used to fill a container from bottom to top, flushing out much of the lighter oxygen and nitrogen. Are there any other advantages? To use a gas flush , you will need to invest in a cannister of nitrogen, or a cannister of argon (usually more expensive than nitrogen), or a nitrogen generator (about $4000, I think). For compressed gas you will also likely pay an annual cannister rental fee, and have to buy your own two stage regulator and hoses. To be effective, you should also have an oxygen analyzer ($1300+) to ensure that you have completely purged the container and that it stays below 0.1% O2. I don't think a single flush will remove all the oxygen, so you will likely need to supply a constant stream of gas into the container. If so, you will need a humidity sensor and a means to humidify the argon or nitrogen as you pass it into the bag. All in all, if you don't already have a set up, my advice is still to use a passive rather than an active system when anoxia is not done on a regular basis. js Jerry Shiner Keepsafe Microclimate Systems Specialists in the design, procurement, and installation of environmental control systems for museums and archives www.keepsafe.ca i...@keepsafe.ca +1 416 703 4696 +1 800 683 4696 The only problem with argon is that you have to have the gas -Original Message- From: Louis Sorkin sor...@amnh.org Sent: 4/1/2009 1:36 PM To: pestlist@museumpests.net pestlist@museumpests.net Subject: RE: [pestlist] freezing Japanese laquer This is a message from the Pest Management Database List.
