Hi Mark, Marcin & all I have the same problem with rusting on the white foam pads, looks awful ! I think an answer maybe the use of a piece of VCI paper placed below the foam piece as suggested on the Anne Black's site.
http://www.impactika.com/antirust.htm Either this or membrane boxes as you suggest, but would work out a more expensive a solution. Would the VCI be enough to combat the action of the Chloride based foam ?

Now tell me storing minerals in cheap Chloride based foam is good!? In my personal view foam boxes should be phased out and replaced with membranes and Rikers...

Vinyl Chlorides! - that answers a long standing question I have had.. I was wondering why a some Micro's I had in Foam (sponge) cases where rusting and all the others in membranes etc and out in the open were all fine (even ones from the same fall). ======== Maybe there is many different sponge kinds, becouse as I say to Drtanuki, half of my collection is in this boxes from a years without opening and pieces are fine. And I live in Poland, not in south of Libia. I hold there irons, chondrites, achondrites and nothing rust here. I especially found that small Gao's stored in boxes with foam stain the foam with rust over time, and those that aren't don't! ======= I have Gao in boxes with sponge. El Hammami slice, Pultusk endpieces, Mt Tazerzait slice and other H5 :))) There certainly appeared to be some reaction with the foam. I have noticed that yellow foam was far worse than the white foam?, presumably different Plastics are used, chlorides would be the reason! ======== I dont know how this looks on other boxes, but here You have special material on foam layer, so meteorite not contact to foam directly. Just look to my photos. Anyway I will not change my opinion. Boxes are perfect, and many times cheaper than membrane boxes or other things ~~~~[ MARCIN CIMALA ]~~~~[ GG 4742912 ]~~~~ http://www.Meteoryt.net [EMAIL PROTECTED] http://www.PolandMET.com [EMAIL PROTECTED] http://www.Gao-Guenie.com GSM +48(607)535 195 ~~~~~~[ Member of Polish Meteoritical Society ]~~~~~~ ______________________________________________ Meteorite-list mailing list [EMAIL PROTECTED] http://six.pairlist.net/mailman/listinfo/meteorite-list ______________________________________________ Meteorite-list mailing list [EMAIL PROTECTED] http://six.pairlist.net/mailman/listinfo/meteorite-list
