Where did you get your Nital from?

I am desperate to get some but without any success.

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

I have not received it as yet but ordered it here;

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

Thank you very much for the reply! Unfortunately, they do not serve Europe.

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?

Ferric chloride seems to be the next best alternative to Nital but
1. it is more difficult to work with as it tends to stain everything... including the sink;
2. the end result shows less contrast than with Nital;
3. it leaves the piece more prone to rust.

As with regards to the etchant store, they used to deliver to individuals until a couple of years ago. I particularly liked their 5% Nital that allowed me to dilute it down to 4% which in my oppinion delivered the best results.

Polishing thr surface to anything above 2000 grit (3000 in some cases) might be counterprodictive as the metal becomes so mirror-shiny that makes it difficult for the etchant to bite.

That looks very much like someone heated a spot on the edge, either to straighten a deformation, or in attempt to re-harden a spot.
