Re: [meteorite-list] Cleaning Chondrites
Wouldn't the moisture associated with bead blasting cause problems? Most chondrites You can put to water for a shorter moment (seweral minutes) without problem. Especially stable sahara meteorites or weathered stuff like Yours where You can't make it worse. Be aware of doing this with fresh material like Benguerir or rusty crap like Ghubara. If You must use water, f.e. for cutting or polishing proces, then put wet samples immediatelly to pure alcohol for a short moment and then heat them carefully. If You put them wet to heating place then hot water in meteorite can start killing iron inside before hot air will remove water. It is especially dangerous in porous meteorites. water --- alcohol --- heating and everything will be OK 36h before plane to Tucson, ajajajj Karrramba -[ MARCIN CIMALA ]-[ I.M.C.A.#3667 ]- 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 Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

Re: [meteorite-list] Cleaning Chondrites
Thanks Ed, but I'm looking for methods much simpler/cheaper than buying more equipment. :) Gary On 20 Jan 2007 at 14:57, Ed Deckert wrote: Gary, An ultrasonic cleaner can be a very useful tool, and not just for meteorites. Jewelry can be cleaned, but one must exercise care as not all gems should be cleaned ultrasonically. Many other things can be cleaned as well. I use mine for mineral specimen cleaning. Those little crevices between quartz crystals in a cluster can be a bear to clean. I have cleaned many geode interiors with it as well. You tend to get what you pay for. Although the cheapie jewelry cleaners can do a satisfactory job as long as you don't use it too heavily. (IMHO) Good luck! Ed - Original Message - From: Gary K.

Re: [meteorite-list] Cleaning Chondrites
Thanks for your advice Marcin. It is very weathered and I will be cutting some of the larger specimens to see what is inside. If they are metal poor I may get lucky.

It will be better to cut them in half or make small window and good polish, becouse usually weathered crap chondrites can be interesting inside. This way I have found 150g of primitive achondrite.

Re: [meteorite-list] Cleaning Chondrites
Pure Alcohol is best. I use water free rubbing alcohol from the drug store. Be careful and don't breath too much in or get too much on your skin. First dry brush as much as possible. Some low W0 or W1 chondrite slices can be further cleaned with sulphuric acid. Now you need to be really careful. I use navel jelly in order to remove rust stains. I have left stuff in for an hour with great results and Zag especially cleans well. With these acids you must know what you are doing so if you are not sure ask for help from someone who knows how to handle these chemicals. Once I forgot a specimen for a few days. Fusion crust completely eaten away. ;) Cheers, tett - Original Message - From: Gary K.

[meteorite-list] cleaning chondrites
Dear List, What is currently the best method for removing fingerprints (with theiracids and chloride ions) from chondrites, using readily available material? While I don't usually handle my chondrites with bare fingers, they have all passed through long chains of custody before I bought them, and it would be sad to watch oxide stains spreading through the matrix and black fusion crusts turning brown. Also, does anyone ever use VCI paper with their chondrites?Am I currect in assuming that it may retard oxidation of metal that is exposed to the air?
