Hi
There is tannic acid in coffee, and seemingly 30 other organic acids as well ( according to my quick google of “tannic acid in coffee”) I assume it is these that are doing the etching? Ken |

I know this is kinda old but I am getting ready to etch a possibly wootz blade with nital 3%. For those of you that use nital 3% what do you do afterwards? Baking soda or a acid neutralizer?

Same here. Baking soda directly on the blade after you rinse it off in water.

Hello Battara. Is this for cleaning the blade after etching? I also use it but I mix it with water then wipe the blade after etching. I haven't tried putting the baking soda directly on the blade. Should I let the baking soda sit for a number of minutes? Thank you

Does any one else find that this tarnishes the finish. I have been using the Hrisoulas' method of polishing with a leather hand buff, cerium oxide, and water to make it pop again. I have noticed that I often dull my edges a bit if they are functionally sharp with the hand buff. Anyone else have this problem or a better technique to suggest? Has anyone tried a block with a pad on it under the leather buff to control it's interaction with the edge more?

Hi Marius
Why not make it yourself it is just Nitric acid, Methanol/ethanol/or methelated spirits I used work in a university chemistry department so i just made it myself, I have a thread on making it up on the forum we conversed before on this http://www.vikingsword.com/vb/showth...ighlight=nital if you go to your local university or perhaps secondary school and explain what you want it for you may be lucky I can explain process to you if you can get materials regards Ken |

Thanks for the link. That is one price mark up. I used be a buyer in a chemistry department so I know pricing.
Raw ingredients for 500 ml would cost under a dollar. I wish I could make and supply the sword collector fraternity at cost. Not being critical here just an observation. Regards Ken |

Sorry to recommend the Etchant store. They only sell to commercial addresses. They are worthless for individuals.
It looks more and more like it's not just them. I cannot find any sellers that will sell it unless you have the proper identification/documentation. I even checked a welding supplier and was told they could not even get it. Does anyone know something that is available that is close to it? Vinegar does not seem to do the job. Thanks.

Since Nital seems next to impossible to come by; How well does Ferric Chloride do when compared to it?
