[meteorite-list] Cunnamula, Queensland, Australia rock
This story appeared on the list a few months ago but according to the "Perth Now" people, it has apparently only just recently been authenticated. There's a pic in the online article - nice looking big rock, at least for one of these kinds of stories. (To our Aussie friends, what's a gidgee tree?!) DG http://www.perthnow.com.au/news/breaking-news/cunnamulla-rock-at-centre-of-dispute-declared-a-meteorite/story-e6frg12u-1225921938055 Cunnamulla rock at centre of dispute declared a meteorite AN ODD-looking rock found in a dirt paddock on an outback western Queensland property is officially a meteorite. The 27.6kg object was resting under a gidgee tree near Cunnamulla, 825km west of Brisbane last year, when it was discovered by disability pensioner Tom King. Queensland Museum curator Alex Cook has officially declared the rock a meteorite. "Not too often meteorites of that size come along, it's the second largest stony meteorite found in Queensland," he said. "It's heavy but the last time a meteorite of this size was found was about four years ago, a 55kg meteorite was found in Winton." A tussle broke out last year after the property's caretaker Tom King found the rock in a dirt paddock at Rywanda Plainview, 70km south of Cunnamulla. Mr King took the rock to his Cunnamulla home to use it as a doorstopper. A dispute erupted between Mr King, the property's owner Keith Wilson and the lessee Angus McLennan. The rock was kept by police until a court finally awarded ownership to Mr Wilson in June. Mr Wilson said he would not be selling the rock but is yet to decide where it will rest when he collects it from the museum later this year. "It's not being sold and it's not going out of Queensland." he said. __ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

Re: [meteorite-list] Rust Question about my stone meteorite. BKF is the best :)
Hi there, well although I still feel relatively healthy, I know my meteorites will outlive me. Historic meteorite collectors know it; the way a meteorite goes, how it is passed from people to people, through the collections, from generation to generation. Yes, we have now the decade, were meteorites are greatly available and already obscenely cheap, but it's a phase. And little money doesn't mean, that we can forget about the respect we should have for these stones. (Would anyone throw his Tieschitz, his Ensisheim, his Tabor in acid? So why an NWA...). Irons, irons are different chapter. If it has around a lot of oxide-snot, rust it is absolutely legitimate to remove it. As it is legitimate to cut, polish and etch irons. But they are pure metal, the core remains unaltered in such procedures. Stones however not. They are damageable. All chemical treatment has to be avoided with them. Removing caliche, removing mechanically rust ect. alcohol not a problem, but everything else is. Just choose the wrong putty, see old discussion with the wrong softener or oils, and within not so long time, your stone will be damaged and blackened cm-deep and a case for the trash-bin. Throw a brown slice of a weathered chondrite, W3 or worse, with some acid in a vacuum cleaner, tear it out, when it's light grey et voila. Throw it then into ebay, without saying a word, and you get a tenfold price. You see how fine the line is? From innocent home decoration aspects to that, what some would call: fraud. And what for? Why can't the stone keep its dignity? Or else, not grandiloquent: You alter the material, afterwards it hasn't the same properties anymore. It will be something different. That's what I meant in my first post. A clear consequence is: It looses its collector's value, the monetary virtu. What will happen with pieces, treated that way, when the owners once will get weary of them? They'll get into circulation. No good. No good at all. I don't agree with Martin. Yes, on each mineral show you can see a lot of pimped, forged, mounted, glued, artificially colored minerals. But stone meteorites? Here and there perhaps a box of UNWA, painted black or treated with oil to sham freshness and fresh fusion crust. But very rarely. Use fingers and nose, easy to detect. And other than minerals and fossils, meteorites aren't bulk goods. The primary and secondary sources of origin are relatively few people, and responsible people. And the rest of the suppliers chain resells specimens like they get them in without working on them (except mounting them in jewellery, watches and stuff). Who of them would do such things? See. So it's really better to let the stones in peace, love them like they are. There are enough really fresh ones around, no necessity for manipulation. It deteriorates the material. Totally different question of course, but very easy to answer: Only if a stone is threaten to decay, then of course provisions to conserve it have to be applied. But we're talking about stone meteorites, not irons. Almost all make zero troubles, and if you store them dry, the number of real bleeders you can count on the fingers of two hands.

We hope that you like the changes. With Jessica Park leaving as Production Manager, we were asked to take over the production of the August issue and look into ways to increase circulation. We wanted this to be the first step in bringing Meteorite into the twenty-first century. We think that we succeeded. Please let us know what you think of the new style; we worked hard on this. Nancy and I could not have done it alone. Carol Nelson was our professional graphic designer and we had advice from Geoff Notkin and Maria Haas. We especially want to thank Maria for all of the work she did. She was invaluable in helping in the layout and in the proofing of the final product, not an easy task. She also took on the task of getting nearly 20 new subscribers and advertisers. No magazine can survive without a source of loyal readers and advertisers. Thank you, Maria. That said, Nancy and I must now say good-bye to Meteorite magazine. We are doing this for both personal and professional reasons. With several key personnel and policy changes at the publishing end, we felt that it was time for us to move on. We will miss the interaction with our readers, but look forward to maintaining the friendships we have formed over the last five years. Anyone wanting to submit articles to for publication should do so through met...@uark.edu. At the moment, we do not know who will be taking over as Editor or Production Manager.

Hi Peter and Tom, And I almost forgot, I also sent samples of Chicxulub microtektites to a researcher in Japan who used them while doing research, that eventually ended up being published in peer-reviewed academic journal. So it's not very common perhaps, but it does happen. FWIW, I keep the majority of specimens sealed in air-tight, boro-silicate glass vials.

Re: [meteorite-list] Rust Question about my stone meteorite. BKF is the best :)
Well, I stand corrected. I guess my statement was much to sweeping a generalization. There are many samples in peoples collections that would be valuable to science and I did not mean to dismiss them so lightly. Mike and Dirk were the first to give me examples of my error and there were more. So I still agree with Shawn! But what I said went to far. Tom In a message dated 9/13/2010 1:42:58 P.M. Mountain Daylight Time, meteoritem...@gmail.com writes: Hi Tom, The NWA 2086 specimen I submitted is being "researched" now. Will this be ground-breaking research? Probably not. But an experienced and qualified eye determined that it has some anomalous properties after examining the specimen in hand. Instead of the usual thin-sectioning, it is going to undergo microprobe analysis to determine the composition of the anomalous features. Granted it is a slim chance that this will be something new and exciting, but if it is, then it's best that the specimen was not altered any more than absolutely necessary. I guess it depends on the nature of the end collection in question. I don't consider my collection to be the end destination for any of the specimens in my cabinet. At best, I am a temporary caretaker and they will outlive me by far. When I pass from this Earth, those specimens will continue to exist without me like they did for the first 4.5 billion years of their existence. I'm comforted in some way by knowing that during my brief privilege of caring for them, I do not introduce anything foreign into them. At best, I endeavour to minimize the damage that they endure for every hour they sit exposed on this alien world that is toxic to their very nature. Without waxing too much more philosophic, I plan on seeing that my specimens end up in an educational institution or museum after I pass. Fate may dictate that one or more of them may end up being scrutinized in some way in the future. Who knows when someone may notice something odd or anomalous that we missed, and a piece will end up undergoing microprobe analysis? That's just my two Bessey Specks though...actual worth may vary.

Re: [meteorite-list] Rust Question about my stone meteorite. BKF is the best :)
Hi Tom, The NWA 2086 specimen I submitted is being "researched" now. Will this be ground-breaking research? Probably not. But an experienced and qualified eye determined that it has some anomalous properties after examining the specimen in hand. Instead of the usual thin-sectioning, it is going to undergo microprobe analysis to determine the composition of the anomalous features. Granted it is a slim chance that this will be something new and exciting, but if it is, then it's best that the specimen was not altered any more than absolutely necessary. I guess it depends on the nature of the end collection in question. I don't consider my collection to be the end destination for any of the specimens in my cabinet. At best, I am a temporary caretaker and they will outlive me by far. When I pass from this Earth, those specimens will continue to exist without me like they did for the first 4.5 billion years of their existence. I'm comforted in some way by knowing that during my brief privilege of caring for them, I do not introduce anything foreign into them. At best, I endeavour to minimize the damage that they endure for every hour they sit exposed on this alien world that is toxic to their very nature. Without waxing too much more philosophic, I plan on seeing that my specimens end up in an educational institution or museum after I pass. Fate may dictate that one or more of them may end up being scrutinized in some way in the future. Who knows when someone may notice something odd or anomalous that we missed, and a piece will end up undergoing microprobe analysis? That's just my two Bessey Specks though...actual worth may vary. (I stole Melanie's turn of phrase, my apologies!)

Re: [meteorite-list] Proper procedures, or How to get your 'meteorite' classified
All Meteorwrongs come from people who don't know how to ID a meteorite. Seems obvious but... If they get the "rock" Identified by an expert FIRST, then this weeds out all the bogus rocks that swamp the labs in the first place. Tracy, you said: "...Point them in the direction of someone who will charge a reasonable fee for a thin section (say, at least $150) and let them foot the bill for wasting everyone's time" Your statement suggests making a thin section of a meteorwrong... Why make a thin section of a meteorwrong? Or am I misunderstanding what you're saying? I get that your logic to deter submission with a $150 fee. Perhaps the fee should be for Meteorite ID first, then another fee for Classification...? I think this is the problem. People are confusing Identification with Classification, and seem to be grouping the two together. They should be separate steps in a process or method. They are not the same thing. When you separate it, it becomes a process by which you can move forward in an organized manner. A method which can be scientific and logical. i.e. A process... -- Hunting Location Recovery Identification Classification Collection --- When you separate it into a individual steps in a whole process the solution becomes more evident. Create a standard by which submissions are taken. Dealers and collectors online are constantly bombarded with "wrongs". If you create a standard process, universities won't be inundated with meteorwrong submissions. Perhaps like someone suggested before a list of approved Meteorite Identification places. This poses a small issue in "who gets approved" and by whom? Also, I read somewhere on-list I believe that universities are required by law to examine ALL submissions? This could also pose a problem, but one which could be fixed easily over time by instituting a program which creates Meteorite ID services. No one I know wants to deal with it though because of the people that won't take no for an answer. But which is the lessor of the two evils? Clogging the system with wrongs, or creating a system that frees up resources. Just my 2 cents... ;) Eric On 9/13/2010 10:57 AM, tracy latimer wrote: I think that it might do a great deal to help weed out the meteorwrongs (or at least the people who insist that they have a meteorite when it's a chunk of asphalt) would be to explain that a necessary step for classification is a thin section and tell them that, unless they have a thin section made, no lab will bother looking at their rock.

Re: [meteorite-list] Crazies on eBay
Dear List Members, It is interesting to note that 50% of the the top ten meteorites in price listed on eBay are not meteorites at all. It is a shame that these bogus offerings interfere with genuine pieces. It is obvious that they self appraised these pieces after listening to overinflated and unrealistic values given by the media. They think meteorites are lying around like an Easter egg hunt. After watching too much TV and barely hiking around the block, they feel that meteorites are everywhere, ready to be picked anytime and any place. Any pile of rocks is now seen as a strewn field, ready to plucked and profited from. It like snagging a sucker out of a babies mouth. All of sudden, they are experts and don't need laboratory confirmation. There is no way that any of these sellers would ruin their multimillion dollar dreams by following proper protocol that is available to anyone with a google search engine and who can read. The only confirmed piece to show up after all of the recent press was qualified by UCLA before the IMCA was even contacted. And then, the finder only contacted the IMCA to locate the best place to cut it. The fortunate individual did his homework online before contacting anyone. I guess a 1 in 10,000 ratio makes the process worth while for some. I would rather put my money into a slot machine (One Armed Bandit) and pull the handle. The odds are much greater of actually winning something substantial than a real meteorite showing up. I am not pleased with all of the false offerings allowed on eBay. This is why many dealers do not bother with it anymore. Who wants to compete in a sea of fakes? With over 4,500 meteorite listings, first class material barely stands out and is why most sellers are protecting themselves with fixed prices. First, it was the China Syndrome of iron ore. Now it is the "Who wants to be the next millionaire clan as seen on TV?" Its feels like I have been bounced around like a baby with a nasty diaper, taking a lot of the enjoyment out of selling on eBay. Sorry, just needed to vent after being contacted yet again by another crazy. It seems to be almost a daily occurrence and a complete waste of time. This is what happens when you sell on eBay. Instead of inquiring about the genuine meteorites I have for sale, these extremely rude people use eBay to ask about a meteorite wrong they have found.

Re: [meteorite-list] Rust Question about my stone meteorite. BKF is the best :)
Hi List, I must agree with Shawn on this one. Does any one know of a case where a meteorite came out of an end collectors collection to be used in any way in research? I am not talking about Bob's 1st Lunar or Adams giant Lunar (These guys are not the end collectors). Any thing that does not degrade the sample and cause damage but makes it more pleasant to display in ones collection is a good thing. Tom Phillips In a message dated 9/13/2010 11:48:36 A.M.

Re: [meteorite-list] Rust Question about my stone meteorite. BKF is the best :)
Hi Shawn, Martin and List, This subject has come up before and opinions vary widely. This is especially true with irons. I've heard of people using Sheath, WD-40, motor oil, transmission fluid, phosphoric acid, alcohol, etc. Treatments which leave any kind of noticeable change in the pristine (or natural) state of the meteorite are often shunned by some buyers. Some buyers don't want an oily feel, a detectable odor, color change, etc. Some collectors prefer to clean off the natural patina or oxidation, while others prefer to leave it. Generally speaking, whenever possible, a pristine unaltered specimen is best for scientific analysis. It's both a question of aesthetics and artificial preservation/restoration. The same debate goes through the classic car circles - purists believe only factory-original parts should be used during restoration, others think it is acceptable to use modern reproduction parts made to original factory specifications. With meteorites, especially all non-irons, I personally subscribe to the "hands off" school of preservation. Oxalic acid might naturally occur in plants and animals, but does it naturally occur in meteorites? (in that concentration and state) If not, I would be hesitant to use it on my own specimens. I can understand the utility of using it from an aesthetic standpoint on common unclassifieds, common high-TKW meteorites (Nantan, Campo, Al-Haggounia, etc), but I wouldn't recommend it for collectible falls, rare types, or any specimens that may be destined for scientific analysis. Right now I have an anomalous NWA 2086 CV3 specimen that is undergoing thin-sectioning and microprobe analysis. The only thing that has ever touched that meteorite during it's stay in my possession is distilled water (once during cutting only) and the diamonds shed by the cutting blade. There is very little contamination to interfere with the analysis. Sure, it wasn't kept in a dry nitrogen-purged containment chamber at JSC (which would be ideal), but it hasn't been altered by me for the sake of aesthetics. I feel more confident in the piece knowing that. Now, on the other side of the spectrum, a common unclassified, highly-weathered, NWA OC that is going to be sliced up and used for display or outreach purposes, might benefit from a good cleaning up and removal of oxide staining. So I'm not condemning the practice, I would just caution against using it as a matter of practice with most meteorites.

Re: [meteorite-list] Rust Question about my stone meteorite. BKF is thebest :)
Hi folks. I think both sides of this debate have valid points. One might ask: Is the cure worse than the disease? While a 'little' rust doesn't bother me, if my 'patient' is being killed by rust I'll most certainly intervene. A pile of crumbling, rusted fragments is of no value to science either. Sometimes rust removal might be considered the lesser of two evils.

Re: [meteorite-list] Rust Question about my stone meteorite.
Re-post as I can never seem to get the subject right when posting from a "digest from the met-list) -- Original Message -- From: "Steve Schoner" To: meteorite-list@meteoritecentral.com Subject: Re: Meteorite-list Digest, Vol 85, Issue 27 Date: Mon, 13 Sep 2010 16:53:12 GMT Martin and all, I too am worried about this trend, using BFK to "preserve" meteorites, especially stones. Having moved out of meteorite hunting due to disability, over the last 8 years I have kept my interest alive by learning the thin section process, and how to make them economically. What I have noticed is that some stones that have been "treated" can be extremely difficult to bond to glass. Any type of oil, or oxygen depleting substance will cause this, not to mention that it also changes the isotopic nature of the meteorite that will show up in micro-probe analysis. A simple soak in pure alcohol will do no harm. Also for some stones and irons, I have used alcohol and sodium hydroxide. One meteoriticist was adverse to this as he said that it would change isotopic nature. But I countered that in that if one looks at the reason for the rusting in irons or stones is the presence of chlorine that is derived from long term exposure to weather and soil. Chloriine from chlorides in the soil attach to pure iron as Ferric Chloride (FeCl3) which is highly hydroscopic, causing a ongoing catalytic reaction where it makes the iron latch onto oxygen thus turning the iron into rust. That is why one finds iron relics on dry lakes that are completely reduced to rust, and also the reason for the so called "Lawrencite" decay of meteorites. A solution of 70% alcohol and sodium hydroxide (NaOH) turns that ferric chloride (Lawrencite) into salt (NaCl) because chlorine has a higher affinity to sodium than to iron. It then creates a brine solution leaving the rusted iron as ferrous hydroxide (Fe[OH[2). (Fe[OH]2) then turns into FeO2-3 upon drying which is plain rust.But before drying the meteorite must be soaked in distilled water which will remove any salt on the surface of in the cracks. Thus with chlorine removed, the ongoing rusting caused by catalytic hydroscopic and acidic FeCl3 stops, The only addition, if any, is a trace of salt caused by this process. And most weathered meteorites will have traces of terrestrial salt anyway. I doubted that sodium hydroxide and alcohol would remove other elements that are bound in meteorite minerals. (Thechemical reaction is more complicated than what I have explained in the above paragraph. But simply stated the result is common table salt and solid stable rust. The chlorine has been removed from the meteorite. And I have done this with stones, such as Lamont, Kansas a terrible ruster.) I think the meteoriticist saw my point with regards to this process, and that that additional salt could be excluded from a micro-probe analysis in the study of irons.

Re: [meteorite-list] Rust Question about my stone meteorite. BKF is the best :)
Hi List, Most museums and notable collections realize that proper preparation is the key to preservation. Slices should be polished on both sides to reduce surface area which can and will trap moisture. A properly applied polish is the most important step in preserving any cut meteorite that contains metal. Tap water containing chlorine should never be used in the cutting or polishing processes. They should be stored in an area that doesn't experience huge temperature swings. Specimens do better in very low humidity. A lacquer coating should never be applied. Some less knowledgeable dealers apply a lacquer coating as a shortcut. Although, it may make the specimen look more desirable, it will never provide a substitute for a professionally applied polish. As a mater of fact, it actually traps moisture inside the specimen, will yellow over the years and is just plain bad. I learned the hard way. I had a several thousand dollar Brenham Pallasite dissolve into a pile of crap in a few short years. The slice actually flexed when I remove it from the safe. The only thing holding it together was the lacquer coating which held long enough for me to throw the specimen into a trash can. I was so disgusted that I never purchased from that dealer again.

Re: [meteorite-list] Crazies - Was Meteorite testing locations - Was meteorite millionaire
I used to invite people to my home so we could examine and discuss their finds. Bad idea. After several experiences with disgruntled "meteorite" owners I had to give that up. Some people get downright mean when you tell them the bad news. I've never seen anything like it in 40 years of buying and selling just about everything else on earth. By the time I wised up, quite a few crazies knew where I live. People have shown up as late as 2 in the morning knocking on my door. I've found rocks in my mailbox, rocks on my porch, rocks on my truck and even had the windshields of several of my vehicles smashed with of course, large rocks. The windshields could have been random vandalism I guess. So, I started meeting people at the public library or if they were particularly paranoid about losing their priceless windfalls I'd meet them at the police station! Keep in mind that it was worthwhile or at least seemed so to me at the time, since I bought over a dozen specimens this way. I've seen even more that were priced beyond reason. The one that stands out was a woman in her mid 50's that I met while looking at some rocks in a local restaurant. She was a cook there. The waitress heard the conversation at my table and told me about the cook who she said had some meteorites. She introduced me to the cook who was a very pleasant, articulate person. I invited her to bring her meteorites and a variety of other collectibles to my house. She said there was too much to take to the library. I thought she meant, too many antiques and collectibles, lol. The next day, the calm well spoken person I met at the diner was phrenetically unloading bushel baskets full of rocks and all sorts of debris. Every rock on her property was a meteorite that she witnessed falling to the ground. Everything else was a tektite. Pieces of plastic tubing were tektites, old molten bottle glass, must have been an old dump on the property, were tektites, like the desert glass she said. She had a half melted rubber tire from an old toy tractor that she knew was a flanged button. I tried my best but there was no authority on earth that could convince her that anything she said was incorrect. At last, as I helped her load her car, she cursed God for giving her this ability to see meteorites fall every night, since no one would believe her. She said that some day we would all learn the truth and she would be vindicated. Poor thing.

Re: [meteorite-list] GoogleEarth & GPS in Meteorite Hunting
Michael, I have the new EVO. It is the first 4G phone by sprint. It too has hundreds of app's. Google Earth is but, one of them that works for this purpose. The navigation app is also super cool. It is voice activated but also displays the exact coordinates where you are standing. To me the coolest app of all is the Google sky map. If you look up at the sky and see a star. Any star, simply hold your phone up in the air and view it as if you are looking through a piece of clear glass at the star and it not only displays the star and names it but it shows the entire constellation it is in. If you move it about the sky it shows every other star up there as well. names it and as you move the phone around it shows the location of stars that are out of view from sight due to the earth blocking it out.. So, you can identify every single star up there just by looking at your touch screen on your phone. Sort of a modern day sexton. Say you see a fireball. Now you an absolutely say it fell between Vega and Uranus. with absolute authority even if you never studied the stars before in your life. And it has two 8 MP cameras. One faces forward the other faces toward you. Yes, today's technology is amazing. No I don't hold stock in sprint. Funny though. I think back when I first started hunting meteorites. I was lucky if I had a magnet on me much less a camera and a GPS unit. And now streaming video and a digital sexton to boot. very cool.

Re: [meteorite-list] Rust Question about my stone meteorite. BKF is the best :)
Hello listers, I wonder what the institutional curators do to preserve their meteorite specimens? Do they actually do anything, or do they just let the specimens in their care rust away? Many years ago, I saw bags of specimens in the lower basement of the National History Museum in London, England. Forgot to ask the preservation techniques used. I remember seeing in the main gallery a layout of the Tenham Australia fall. Of course it was behind glass, but I did see what appeared to be a few flecks spalling off some of the larger specimens. Be interesting to see if anything is done in the way of meteorite preservation without compromising the specimens scientific worth. We all know the Orgueil meteorite was artificially contaminated by the introduction of foreign material. Would the use of BKF be doing the same thing? Chris.

Re: [meteorite-list] Rust Question about my stone meteorite. BKF isthe best :)
Hi Martin, I agree it doesn't sound like a good idea. Personally I wouldn't do this, at a pinch I would treat an Iron meteorite if it was the last hope of keeping it alive! However this type of thing has actually been done for many years, other methods are also used such as galvanic cleaning, and my favourite pet hate- people putting on 'Kurust' rust stopper that turns the fusion crust jet black, they are all age old treatments. The same things happen in the mineral world, many crystals are oiled, polished and treated to enhance colour. I suppose at least Bar Keepers Friend (or renamed: meteorite sellers enemy) only effects a thin outer layer of the rock, the washing and drying at 200 degrees for several hours is probably much more destructive.

BKF is the best :) Jim k and the List, I took your advice and used the Bar Keeper Friend on my L6 meteorite fragment to remove the rust on the surface of the meteorite due to age and I would have to say, wow, this stuff really works. The meteorite looks so much better. I can see the true color of the meteorite, I can see the texture and the gray matrix. I have a link down below of before and after images of the meteorite :) Take a look and you will be amazed of the results. http://www.flickr.com/photos/48262...@n03/4985819064/sizes/l/in/photostream/ Shawn Alan IMCA 1633 eBaystore http://shop.ebay.com/photophlow/m.html?_nkw=&_armrs=1&_from=&_ipg=&_trksid=p 4340 [meteorite-list] Rust Question about my stone meteorite.

I've used fine grit sandpaper to remove rust from slices. Lay the sandpaper on a hard flat surface and gently rub the meteorite onto the sandpaper. For removing rust from iron etched slices, I use a product called "Bar Keepers Friend", this can be found in most grocery stores cleaning supplies isle. It comes in a powder form, so you have to make a thick liquid out of it. Wet the meteorite with warm water then apply the liquid BKF. Rub it onto the meteorite with your finger gently. Rubbing to hard can damage the etch. After removing the rust, rinse the piece, soak it in alcohol and bake it dry in an oven about 200 degrees for 2 hrs. You can try the BKF process on a chondrite fragment and use a toothbrush to scrub it. It should work but you might want to experiment with a cheap uncl. NWA first.

If any
Re: [meteorite-list] Rust Question about my stone meteorite. BKF is the best :)
Humhem...please! No offense. It's absolutely you're private affair, what you're doing with your meteorites. Though in general I think it's a big No-No to manipulate stony meteorites that way, to artificially bleach them. (Just was looking, "Bar Keeper Friend"s main reactive agent is oxalic acid). Stone meteorites are no irons. In my opinion such a treatment will make them to a certain degree worthless, as they can't be used anymore for scientific measurements. What I would urgently expect, is to avoid, that such bleached chondrites would be brought in circulation. The meteorite sector, other than the minerals and fossils sector, all in all was so far relatively spared from manipulated or fudged specimens. It would be in my very personal opinion everything else than good, that W2, W3, W4 material now would be pimped to be suggestive of being a W0 or a W1. I hope we all can agree about?
