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.

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?

Re: [meteorite-list] Alcohol + water + NaOH
I'm not at all familiar with what you are trying to accomplish by soaking an iron in a basic solution of sodium hydroxide for a week, but it sure doesn't sound like a good idea. The best thing to do to prevent rust is to vacuum seal it in a glass container. Also, if you must handle it, wear cotton gloves. Michael in so. Cal.

Re: [meteorite-list] Alcohol + water + NaOH
Mendy...I think Francesco is talking about the preservation process and not the etching. I have managed to preserve irons to some degree using NaOH solution without alcohol...but I was a bit hit and miss with the dilution and times they were left for.
