Re: [meteorite-list] Nitol Etching Formula
The short answer is that it depends. Some people use the weaker 10% Nitol and others use closer to 30% Nitol (I am pretty sure based on fuming 63-67% Nitric acid), and some use everything in between based on the actual meteorite being etched. I use the 63-67% Nitric acid and mix it with 99.9% methanol (acid into methanol slowly). The acid you are considering is just diluted with water and depending on what you are etching, should be fine. I would just increase the acid into the alcohol and use a 90%+ alcohol. My view is that etching is far more art than science and requires much experimentation to get "right". Hope this helps.

I know the basic formula for Nitol etching solution is 90% alcohol and 10% nitric acid. BUT what are the strengths is this formula based on? For instance, you can readily buy 70% and 90% alcohol at any store and nitric acid comes in a huge variety of strengths but 63% seems to be the most common. The reason I ask is that I have an acquaintance that has 1/2 gallon of 50% strength nitric acid that he would love to give to me but because he can not easily dispose of it BUT I need to determine the correct ratio before I accept his gift because I am pretty sure the nitol formula uses stronger acid I hope this makes sense.

Re: [meteorite-list] Nitol
or the ol is the read end of alcohol maybe because it's at the end of Nitol Jerry Flaherty - Original Message - From: D To: meteorite-list@meteoritecentral.com Sent: Tuesday, February 20, 2007 10:51 PM Subject: [meteorite-list] Nitol Been reading some posts regarding etching I believe the term from the science of metallography is Nital...NOT Nitol.

Re: [meteorite-list] Nitol
Actually, the ol is from the last two letters of alcohol, not the first, and I believe comes from the common short hand abbreviation used for alcohol in various scientific and medical disciplines. I've never seen nital used, in college or since, though as long as everyone knows what we're talking about, I doubt it matters. Frank Prochaska - Food fight? Enjoy some healthy debate in the Yahoo!

[meteorite-list] nitol / FeCl 3
Hi Desmond and list, Yes, diluted (5% or less) ferric tri-cloride ( Fe Cl 3 ) works well. I used it for many years for some art work (etching cupper plates) and I also used it to etch iron meteorites - it's not a very harmfull acid. In Switzerland you can get it in every drugstore. Peter
[meteorite-list] nitol
hi, all, I got some suspected iron meteorites. I want to try to etch them. Does anyone know other easy methods to etch instead of using nitric acid? I find it difficult to buy nitric acid and quite danger to handle myself. Could anyone tell me other methods? Any existing spying chemicals or solutions that I can buy easily and less harmful?

Hi Desmond and list Some time back it was posted that ferric cloride (a pc board etchant avail at radio shack and electronics suppliers) works well.
