Re: [meteorite-list] List of known Rusters?
Hi Jonathan: I did a search for D96 Gun Oil on the internet. I contacted the supplier of this product and he says they will not ship small amounts to Canada. He referred me to some Canadian Dealers but they did not reply to my e- mails. Perhaps they don't stock the stuff anymore. Shipping stuff like this across the border can be problematic and also costly. I phoned a gun collector friend of mine and he says they don't use gun oil anymore, just cloth impregnated wipes. He says in our cold climate when hunting seasons are open gun oils tend to gum things up. He suggested using clear paste wax, auto or floor types. I wonder if anyone has tried this?

Re: [meteorite-list] List of known Rusters?
Hi Ed, The wax idea sounds good. Keeps the water out, but still breathes (lets oxygen in and out). Have you thought about microcrystalline wax, instead of clear paste floor wax? Try a company like 'Clarus Specialty Products' or 'Caromex International'. Ask for a microcrystalline wax that melts easy at, or below, 175 C ( ~ 350 F) and that has a good penetration grade. As it cools to ~ 100 C (200 F) take it out, and rag it off You are good to go... If you have excess in some wax in certain tough areas, you can just torch it out or simply re-bake it. Try it on something small Let me know what you think... In the Great White North, you might try WITCO Canada (814-368-6111) You might try their Witco 180 M Microwax...

Perhaps we could develop a rating system (1 to 10), (stable, mostly stable, partly stable, unstable, extremely unstable) or something similar and a listing of specimens.

Hi list, rustophobes - with pleasure I post here the link to our colleague Ben's Website (who isn't list member, but reader) http://www.aranemac.de/mets/rost.html In cooperation with collector-friends of the Meteorite-Mineralien-Gold-Forum.de Ben worked out a system of 5 gratuated rust levels in regard to iron meteorites. As the website is in German please allow me to translate the 5 (colored) levels: Rust Level - 1 Staying stabile for a very long time without adding desiccants or other assistive equipment RL - 2 Pretty indulgent, ruster are a decesive exception RL - 3 In the most cases without problems over a few years, but one can get a ruster as well occasionelly RL - 4 Problematic irons, difficult to keep stabile, rusters are in majority RL - 5 Extreme rusters, the process usually ends with complete decay; stabile pieces are extremely rare The rest should be self-explanatory.

Re: [meteorite-list] List of known Rusters?
Hello List. Regarding Dronino, Mike Miller has done some great work for me over the past few years, and he recently resurfaced a large 2Kgram slice for me and the work is remarkable. Now with beautiful rust-free inclusions and no sign of regression... although I do keep it wrapped in saran-wrap with a coating of Hoppe's 9 (recommended by Kevin in his book, and I agree it's good).

Hello Jason, and all, I certainly agree with you when it comes to Dronino and Nantan, I have heard them called temporary meteorites and that does fit quite well. However I have right here a slice of Brenham about a foot across, it came from an old collection and it was cut/polished by Al Lang some 20 years ago, there is no varnish, nothing on it, and not a speck of rust. I know Colorado is relatively dry, but it was in a much more humid area before coming here. Same thing with a large end-cut of Brahin, from that same old collection, again no varnish or other protection and again, no rust. I wonder if the initial care it received right from the discovery does not make a much bigger difference than we usually think. For instance I have had slices of Fukang, some rusted quickly, some never did. Same thing with Chinga, Montdieu, Admire. And they were all kept here under the same condition. The only thing ever used on them (and not all of them) is Bill Mason's spray. Any other ideas? Anne M.

Re: [meteorite-list] List of known Rusters?
One thing you will want to stay away from is lacquer. Some dealers in the past didn't know any better and used to coat meteorites with lacquer, especially rusters. This doesn't allow the meteorite to breath and traps moisture inside the piece, accelerating the oxidation process. A few also used lacquer as a shortcut instead of finishing a polishing job. It would give the illusion of a well-prepared piece but there is no substitute for a fine polish which reduces surface area that can trap moisture. It is also very important to wipe down prepared meteorites after handling them. I saw a dealer applying car wax to a polished surface one time and he swore by it. Rusters seem to do better in an environment that doesn't have huge temperature swings with free circulating air. The best bet is to avoid rusters all together unless you live in a dry climate. I tend to avoid meteorites that need any kind of maintenance. This is one of the reasons I gravitate towards achondrites. I found that Rusty Mason's meteorite treatments are the best. Hopefully, he will be in Tucson where the Meteorite Kits can be ordered.

Hi everyone, I've had great luck with the Campos from Bob Cucchiara (meteorite madness on eBay). I hand them out all the time to students. The only preservation I use is a spray for guns called Barricade available at Gander Mt. outdoors stores. It works well. I also still have an intact Nantan individual I got long ago from list member Walter Branch. A rarity like that must be worth millions. As for some others: * Dronino - can be both good and bad. I've got some that are in a hurry to return to the Earth and a couple that are perfect. * Canyon Diablo individuals - slow flaking * Muonionalusta - I've yet to find a stable slice out there * Gibeon - I've got one impossible slice and a couple of very stable ones * Mont Dieu - good but needs to be sprayed regularly * Lueders - no problems * Saint Aubin - a ruster Then there are the chondrites that get tears in their eyes (bleed).

Hi Bob and List, Then there are the chondrites that get tears in their eyes (bleed). Dhofar 10 comes to mind. .. Oh well, yes! My Dhofar 10 endcut that I purchased in 2001 kept bleeding / oozing for years until it finally surrendered about two years ago. No more chloride tears left! It's been stable since then. Another chondrite that just loves to produce plenty of rusty stains is NWA 2894 (probably L3) even though I know it's been cut and prepared professionally!

Re: [meteorite-list] List of known Rusters?
I have a Nantan and it is perfect, end cut with an etched face. It was cut at least 4 years ago. Just depends on the piece and definitely how it was prepared (if cut).

Hi Ed and Listees! We had this discussion at the biggest German Met-Forum (Meteorite-Mineral-Gold-Forum)some time ago. One of our members has created a list of Roster-Levels which uses the knowledge and experience of all members so far. See here (please scroll down to answer #73): http://www.jgr-apolda.eu/index.php?topic=1368.60 Color speaks for itself! Hope this will help you a little...

Re: [meteorite-list] List of known Rusters?
Hi Ed and all, This has been discussed before and I believe the consensus was that WD40 can have moisture in it that will promote rust. It depends on the batch but there is varying degrees of water contained in this lubricant. It might not be so good for Nantans but more stable irons like Gibeon would probably be fine. A good grade gun oil like Birchwood brand, Barricade seems to do better in my experience but smells a bit. Bottom line here, Nantans are often unstable and may have been weathered to the point you'll never be very successful at drying them out. These are notorious rusters. I like very much your idea of a list of meteorites that are problems specimens. Perhaps we could develop a rating system (1 to 10), (stable, mostly stable, partly stable, unstable, extremely unstable) or something similar and a listing of specimens. Even the metal in ordinary chondrites can rust. An example is Ghubara, Omen. About half of the pallasites out there are problem specimens, and a number of irons are.

Re: [meteorite-list] List of known Rusters?
A great gun oil to use is G96. Unlike many of the others it does not have the odor many have and it leaves less of an oily feeling on the meteorite. Not too easy to find but Google it to find mail order suppliers. Maybe the mineral dealers from China can start using it. Too often their specimens are so heavily oiled that you're afraid they will slip out of your hands if you pick them up.

Re: [meteorite-list] List of known Rusters?
I wouldn't use WD40 on any mets, as it contains water and smells. Like Al mentioned, a good low viscosity gun oil like Remington Rem-Oil wipes work well without any aroma. As an added bonus the application wipes clean mets while lubricating them. Also, as Matt mentioned, there are problem and stable specimens from most any iron or pallasite meteorite. Another factor is how they were prepared. And its not just irons and pallasites, as I've had Ghubaras and Tsarevs that self destruct by themselves. gary On Dec 6, 2010, at 8:00 AM, al mitt wrote: Hi Ed and all, This has been discussed before and I believe the consensus was that WD40 can have moisture in it that will promote rust.

Re: [meteorite-list] List of known Rusters?
The formula for WD40 is secret. however... ...WD-40 literally stands for Water Displacement, 40th attempt... http://www.wd40.com/faqs/ WD40 does not contain water... ;)Wouldn't it seem counter intuitive to add water to a product which displaces water? Wired Science article about the ingredients of WD40: http://www.wired.com/science/discoveries/magazine/17-05/st_whatsinside ...What does WD-40 contain? - While the ingredients in WD-40 are secret, we can tell you what WD-40 does NOT contain. WD-40 does not contain silicone, kerosene, *water*, wax, graphite, chlorofluorocarbons (CFCs), or any known cancer-causing agents... http://www.wd40.com/faqs/ Nantan has a bad rep for rusting, however, usually only the outer surface of the irons are rusted. Smaller irons rust deeper into the interior of the metal in relation to it's size. The level of oxidation depends on the size of the specimen and partly on where within any given specimen the slice is cut from. The treatment and prep work on a finished piece of etched Nantan also plays a large part in whether it rusts or not.

Re: [meteorite-list] List of known Rusters?
Hi Ed, I've treated all my metallic meteorites with Rig. It is a rust preventative used for guns. Of all the meteorites treated with Rig, none have shown any evidence for rust. I've had them for about 4 yearsnot a speck of rust. I have one Campo that was pretreated by the seller with some sort of dark colored supposed protectant, and it has slowly started to rust away. I figure that Campo will be almost completely rusted in another 5 years. I wish the seller had just left it alone, and I would have treated it with Rig, and it would not have had any rust on it. One problem with Rig. I don't think it's manufactured anymore. Too badthe stuff REALLY prevents rust, and you can't even tell it's on the meteorite. You just apply a thin coat (it's a type of grease, but disappears when applied). The meteorites are not oily at all after treatment. Once I run out of the stuff, then I'm in the same boat as everyone else.

They can supposedly be treated to prevent rusting - not having owned any of these meteorites because of the horrors I've seen (well, we once had some Nantan, and now have several), I again will not comment on the effectiveness of these treatments; I've no idea if they work or not.

Re: [meteorite-list] List of known Rusters?
Hello Jason, and all, I certainly agree with you when it comes to Dronino and Nantan, I have heard them called temporary meteorites and that does fit quite well. However I have right here a slice of Brenham about a foot across, it came from an old collection and it was cut/polished by Al Lang some 20 years ago, there is no varnish, nothing on it, and not a speck of rust. I know Colorado is relatively dry, but it was in a much more humid area before coming here. Same thing with a large end-cut of Brahin, from that same old collection, again no varnish or other protection and again, no rust. I wonder if the initial care it received right from the discovery does not make a much bigger difference than we usually think. For instance I have had slices of Fukang, some rusted quickly, some never did. Same thing with Chinga, Montdieu, Admire. And they were all kept here under the same condition.

Re: [meteorite-list] List of known Rusters?
Hi Anne I am sure it was from Al's nearly perfect prep work and it may have been one of the early masses found in drier areas. I have a super Nantan endcut and a pretty nice Brahin (both several years ago) and 2 year old Fukang slices with no rust. When I choose pieces I look for ANY evidence of chlorides on the surface and in cracks (use a hand lens). Regardless if someone says it has been stabilized.

Re: [meteorite-list] List of known Rusters?
I think It has a lot to do with both the Brenham specimen and the preparator. While in Kansas I saw a several year old Brenham endcut in the home of Jerry Calvert, no preservation I am aware of. And then there's Mike Miller who has done magic with the 200 pound Brenham I am selling large slices of. Been slicing away for over a year and sending out to the four corners with no callbacks. My Admire slice from Mike is perfect after a year while my 2kg individual rusts away to nothing...there is something in the process. Marlin has been cutting for Steve with good results as well. I just haven't seen a recent Brenham rust. All but one of the major auction houses are now carrying specimens supplied by myself, the stigma is still out there. BTW, the largest of the Brenham slices is presently pictured on my Facebook page for ND Mets I have three perfect Nantans where I admit one needs to be more selective.

I wonder if the initial care it received right from the discovery does not make a much bigger difference than we usually think. For instance I have had slices of Fukang, some rusted quickly, some never did. Same thing with Chinga, Montdieu, Admire. And they were all kept here under the same condition. The only thing ever used on them (and not all of them) is Bill Mason's spray. Any other ideas? Anne M.

Also, stay away from Nantan, Dronino, Campo, and Muonionalusta...unless they've been professionally treated. Brahin is also cursed, as are Brenham and Admire. They can supposedly be treated to prevent rusting - not having owned any of these meteorites because of the horrors I've seen (well, we once had some Nantan, and now have several), I again will not comment on the effectiveness of these treatments; I've no idea if they work or not. All I know is that all of those meteorites are predisposed to self-destruction.

Hi Greg, Please tell us where you live, is it humid where you live?

Hi Ed, I've treated all my metallic meteorites with Rig. It is a rust preventative used for guns. Of all the meteorites treated with Rig, none have shown any evidence for rust. I've had them for about 4 yearsnot a speck of rust. I have one Campo that was pretreated by the seller with some sort of dark colored supposed protectant, and it has slowly started to rust away. I figure that Campo will be almost completely rusted in another 5 years. I wish the seller had just left it alone, and I would have treated it with Rig, and it would not have had any rust on it. One problem with Rig. I don't think it's manufactured anymore. Too badthe stuff REALLY prevents rust, and you can't even tell it's on the meteorite. You just apply a thin coat (it's a type of grease, but disappears when applied). The meteorites are not oily at all after treatment. Once I run out of the stuff, then I'm in the same boat as everyone else.

Re: [meteorite-list] List of known Rusters?
Hi Tim, I live in Prescott Valley, AZ. That definitely helps in preventing rust, I'm sure. All I can say is, the Campos, Sikhote-Alins, Canyon Diablos, Muonionalustas, etc. that I've treated with Rig look fine. Those that weren't treated I've given away, except one Campo that I've held onto, just so I can keep track of what happens when one has been treated with the black substance that the dealers put on. I have to clean the area beneath that Campo just about every weeklittle chips keep falling off, revealing a rusty interior. Regards, Greg L.
