These pens are lovely. How would I make them?

I found that pen without anodization. It's titanium.
Likely, they use sponge or brush anodizing to get the color. That's similar to regular anodizing, but instead of immersing the part in solution, you connect a lead to a sponge or soaked brush and it only anodizes when you make contact.
anodizing starts at 9 minutes in. I watched on mute and fast forward just to see if it showed the process well enough, so I have no idea the actual quality of the video overall.

Looks neat, doesn't it? Anodized titanium coating is very, very thin and very fragile so this would be a 'looker' not a daily user. To get the brilliant colors requires an etch of HF acid or Multi-Etch followed immediately by the anodizing process. If you look closely, notice there are no reds or blacks and orange requires a bit of imagination.

When you say HF, do you mean hydrofluoric acid? I don't know why I thought that was at least a semi-controlled substance.

If I remember correctly BradG has posted some anodized pens and perhaps a tutorial on how he did it.
I couldn't find his tutorial, but those links will give you some ideas!
Aluminium, Anodised Purple Kitless Fountain pen
Handmade with aircraft grade aluminium, and anodised purple, featuring a German JoWo Nib Will be half a dozen colour variations of the same pen over the next few days, so il just post them as replies on this thread rather than creating a new post for each one.

Yep. Hydrofluoric Acid which is one reason Multi-Etch was developed. It's still nasty, requires ventilation, works best heated, eats nearly everything except plastic.

Those are awesome pens. I'm considering getting into kitless at some point. I keep seeing gorgeous reasons to try it

Including anything organic like your skin and bones lol. My high school chemistry teacher used to be a chemical engineer and would talk about what it would do to you at a cellular level.

Look him up on YouTube, Brad Gothard. He had a three part tutorial on anodizing aluminum.

I mostly know how to do from when I was going to anodize some lightsabers I made in school for machining. Have some of the equipment, but my lathe can't thread for crap, so I haven't finished those sabers (7 years later lol)

The process for anodizing Titanium is completely different. Titanium color is achieved by different depths of oxidation where aluminum uses dye for color.
Here is the link to Brad's tutorial on Anodizing: https://www.penturners.org/resources/how-to-anodise-at-home.189/
You can also find it under the Finishing section. Brad also posted a tutorial on Etching. Here is a link to that as well:

Make sure to read the entire post. There are great follow up questions.
