Kaweco Brass FP, speed up brass patina



Recommended Posts

I like when the brass parts of my pens developed over the period  of usage a patina.
But it takes time...

At my new Kaweco Brass FP I want to speed up this process.
It is not a expensive or rare pen...
 

With all the suggestions found in the net to create at brass a patina I choose 
vinegar essence with salt.
I put the parts above the liquide level in a closed box together with the vinegar and salt.

After 3 hours, the high glossy surface was gone and the brass has a nice patina.
The green rust was easy to remove mit water....
 

Now no fingerprints at the surface, no micro scratches and high glossy surface....

The pen has also a much pleasurable feeling.

For a funkier look bury it in a flower bed, or compost heap for a week.

I think this would be too extreme 🙂

Steampunk variegated patina. 😁

I feel tempted, mostly for the green patina, which looks gorgeous. Yet, I think I almost prefer to wait for the real, irregular thing.

 

Thanks for the heads up!

Doesn't most brass contain some lead?

 

The Kaweco brass pens are manufactured from Eco Brass, and are lead-free. I would not expect the cheaper clones would use this material.

Vintage. Cursive italic. Iron gall.

Which might -highly hypothetically- explain why the clones are all varnished.

 

Interesting, I hadn't thought of this but now you mention it, the clones I've had rattling in a pocket and which are now losing the coating, seem to have a silvery color underneath instead of the "goldish" color of the Kaweco, which has had me thinking for a couple of weeks if they were not made of a material other than brass (or a different quality one). Now I wonder if there is an easy test to tell lead content in brass.

 

As Alice would have it, "Curiouser and curiouser!".

For better machining and fabrication brass can contain lead. 

Within the European Community is since 2018 a declaration for brass and bronze and other

copper-lead-phosphor alloys necessary:

 

„The classification requires the creation of a 
safety data sheet (SDS) and its transmission 
to the customer. 
This applies to all lead-containing alloys 
with more than 0.3% lead content or 0.03% 
for lead-containing powdery material, 
in which the protective measures when 
processing these substances are also 
pointed out.“
Translated from: 
German Kupferinstitut

From Kaweco is no data sheet at their web page available. I guess that therefore the lead content is below 

0.3%

But I wrote a Mail to them for confirmation.

You are right……!

I just found at their web page:

„It is made entirely in Germany from the well-known eco brass and only has to go through very short transport routes. The brass used is lead-free and as it is untreated, an individual patina develops over time through use.“

No need to sound so surprised! :P

      Not sure if this has been suggested already but would a setting for localized regions or chapters in FPN be helpful? I don't know if there is a way to find local FPN members who would be nearby. I don't know if we want to be discoverable but a setting to know how many members are in 25, 50, or a 100 miles of each other might be helpful. We can create a regions specific network like Craigslist where people could use that to connect with nearby members, conduct in person sales, arrange FPN meetups

      Hi again all, I forgot to tell y'all that I made the post about Sweden ink PIF. Most have probably found it long ago, but here's a link, anyway:

      I read your blog post and all the replies with much interest. I'm a FP user in Australia. Been part of this forum for years but rarely post. I did come across your ink sharing thread and considered participation. For me it's not lack of interest but lack of time to play around with FP and inks. I'd feel bad to put my hand up for the box and just have it sit until gosh knows when...   I also think that the FP community in Australia is smaller, and I wonder how many in the community are

      Even so, you'd end up with a fragmented list, and it becomes an O(N²) process for each prospective requestor to check what is available: effectively recreate the list of currently active servers (without any reliable up-to-date info upfront about the inks and number of samples on offer in the thread) from the sequential list of posts, which may be spread over two or even more pages, and then query each server independently to check what is currently on offer.   It comes down to not hav
