Re: [meteorite-list] Alcohol + water + NaOH
Phil, 70% Nitric Acid is fairly common. Nital mixtures vary. So 'best' is subjective. Very dangerous stuff! Use safety gear.

I will grind, polishing and etching it ... and after for prevent rust and stabilize it I'm planning to use the method alcohol + water + NaOH . But I have few question: Ethanol at 96% works fine? I have to use distilled water or normal water? For 100ml of solution I have to use 70ml of ethanol and 30ml of water, is this proportion correct? How many grams (or spoons) of NaOh I have to use? How many days I have to leave the slice in the solution? 7-10 days? In this period I have to change the solution or the first potion works fine for all these days? And after? What I have to do?

[meteorite-list] Denver Show Chelyabinsk and other meteorite prices.
Hello Listers, So I stopped by the Rock show yesterday at the Ramada inn for a bit and walked around with a friend. I saw a lot of minerals and some meteorites and the ones I saw, it seemed Chelyabinsk was popular. The lowest price I saw was $8 a gram and the the top was around $30, but those where for cherry pieces. The new jedi cm2 was priced at $30 with one room. Sikhot Alin was prices at .50c a gram to 3$ a gram for cherry pieces. Ill be there again on Friday and that's when ill take my time in the rooms and also be at the auction so I can meet people for the first time in person and also hope to see people I haven't seen for ages. Lastly, if your there and have a room let me know where your room is at :) Shawn Alan IMCA 1633 ebay store http://www.ebay.com/sch/imca1633nyc/m.html http://meteoritefalls.com/ __ Visit the Archives at http://www.meteorite-list-archives.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
Re: [meteorite-list] Alcohol + water + NaOH
I would use steam distilled water insted of alcohol. Less dangerous. Have had personal bad experance with nitol. If you use nitol, then keep in a ice bath to keep it stable. Thanks, Derek.

Re: [meteorite-list] Alcohol + water + NaOH
I have purchased Nital from chemical-supermarket.com. Premixed and much easier to not have to worry about improper mixing techniques and proper ratios. Shipping is a little costly due to safety, but still worth it for me. I normally get the Nital 10% Nitric, but they have different ratios available. They have a 69.5% concentration of nitric acid also if you want. http://www.chemical-supermarket.com/Nital-10-Nitric-250ml-Micro-Etch-Solution-p425.html Aras From: Joshua Tree Earth Space Museum dori...@embarqmail.com To: Meteorite List meteorite-list@meteoritecentral.com Sent: Thursday, September 12, 2013 10:17:36 AM Subject: [meteorite-list] Alcohol + water + NaOH Francesco: Do you mean sodium nitrate (NaNO3)?

Re: [meteorite-list] Alcohol + water + NaOH
Derek's recommendation brings up an interesting point. What is the function of the alcohol? Post etched irons are usually rinsed in distilled water anyways to remove the Nital, so why use alcohol at all?

[meteorite-list] Possible Ancient Meteorite
I had an archaeologist email me today asking about custom labels, and also if I could help with identifying a possible ancient meteorite he found this year. I received permission to send this question to my fellow colleagues which may have more insight into this topic. Read below, or click on link to see his photos... http://www.meteoritelabels.com/Ancient.htm Cheers, Roman Jirasek www.meteoritelabels.com Copied email follows I am an Archaeologist and recovered a meteorite in 2013, on private property in Sparta Greece. This meteorite was found inside an ancient vase, and was buried with human remains. We dated this site to approximately, 220 BCE to 130 BCE, but have not yet carbon dated the item. I do not know of any meteorite falling on or near Sparta Greece. Since the meteorite was found inside an honorary vase, we suspect it was held in high regards, and more than likely to remember a battle. The only battle recorded that had a meteorite that fell during the battle; was with ancient Turkey and the Spartans. It actually stopped the battle for two days, thinking it was a sign from the gods. Many of the Spartans recovered portions of the meteorite is a sign of victory from the God of Mars. I have enclosed a picture of the meteorite. Can you tell me? Of any meteorites that fell prior to 220 BCE, since we know that was the earliest date, since the meteorites was buried with the hoplite soldier. We assume the meteorite obviously fell before that date. This would help us, with dating the find. Additionally what would the selling price be if it were to be sold. The meteorite? Thank you Douglas Roth. Phoenix, Arizona. Sparta archaeology. Yes, it is fine to forward the info and pics.
