Did I just OVERPATINA my blade ?

[Edgenut]

Please do inspect these pictures and see if you can tell if I overdid it

This is the first time I did it and I did so with mustard so it might have had water in it

It does have brown streaks in after all : /

Can't really over do it unless you leave it in strong acid for weeks and let it eat the blade away.

IMO you should have went longer. Personally I like ferric chloride, I get these results in a minute or less.

Looks fine to me. If you haven't done so already, you might rub that white eraser seen in your pics on the blade, and look for any brown/red coming off. If so, that's RUST, and should be cleaned off. Scrubbing it with baking soda & water will do that. The more firmly-set black oxide (patina) won't be affected much by that, if at all.

If you're still worried about having too much patina, you can always polish it off (Flitz/Simichrome) and do it again. No real harm in doing so.

(And water in the mustard wouldn't be an issue anyway, as compared to the vinegar in it that's doing most of the oxidizing and/or rusting. Even the big jugs of white vinegar at the grocery store are only a 5% concentration of acetic acid; the rest is just water. )

Just like Jason B. said probably would have left it in longer. Looks cool though, I like it.

Thank you for your responses ! I used the rubber and mostly took EVERYTHING off . Ill use vinegar next time plus I'll leave it longer. Doing a pattern with a paper tower soaked in vinegar might be another thing altogether. The microstripes you might see in those pictures were done with a tooth brush. Again, thanks for the help !

I accidentally acid etched an opinel using the paper towel method. pro-tip, don't leave it overnight!

 

[Douglas Thor]

Yup. you ruined it. you should sell it to me for $4, immediately! lol

Looks great to me. I've used white vinegar on a Stag Medium German Eye Stockman and it came out awesome.

I use ferric chloride now, but my previous patinas were done with plain white vinegar soaked into a paper towel wrapped around the blade and left for a couple hours. David mentioned the baking soda/water paste. This is the step that neutralizes the acids and stops the process. Very important. Once you've scrubbed it with paste (toothbrush is a perfect tool for this), you can then rinse it under tap water, dry it off, and apply your choice of oil.

In addition only: degrease with alcohol before starting, and afterwards, rinse with the hottest water you have.

Nope not even close, maybe even under patina it.
Looks good OP, if you don't like it you can always sand it off and retry!

Looks good to me:thumbup:

Condor is a solid brand of blades, my golok machete has been through hell and back and still puts out like a $5 hooker
