u your state archives or get in touch with your state dept of Agriculture.Look into Nitrogen gas as a suffocant.It is considered harmless in reasonable use within a museum.The cost is not the gas but the special films used that prevent gas ase look up a Merck Index I am having problems seeing what I am typing .Dr.Marc Gilberg at the Getty in California can give you more info.I am sorry I do not have his address here.Len Hambleton-Objects Conservator North Carolina Museum of History Net address is History @Nando.Net. I will be out of the country until 16th.Methyl Bromide sets off alarm bells for me as a conservator.Nitrogen gas is cheap.You will need a portable Chamber like Rentokils in Britain. I have all the info but am not at my desk right now.You will also need a Oxygen meter with fine probe to see if nitrogen has displaced oxygen in bag or chamber that artifact is placed.Also for small items try Ageless Z from Conservation Materials in Sparks Nevada .It is a Mitsubishi Product.Bye for now Regards Lenin6 8 On Wed, 4 Oct 1995, Victoria Leachman of The Science Centre and wrote: > We are shifting our collections of mainly furniture, European > domestic technology & farm equipment from an old warehouse into a new > building.
