I find Ochre hard to clean and prone to staining. Don't leave it in a pen to long and clean it promptly. Great color and worth the extra attention.


How long is too long to leave ink in a pen? Just want to know the amount of time it takes fr some inks to stain the inside of a pen.

How does the staining process (for pens) work by the way? I imagine it doesn't simply occur immediately on contact and that there are other factors at play.

 

The way I think about it, there are a few different sorts of "stains".  One is just ink getting caught up in the lubricant of a piston or plunger filler, which is not really a stain as such, but it appears that the ink cannot be washed out completely.  Another sort of "stain" is a dry residue that resists rinsing but can be wiped out, which happens a lot with the cellulose-reactive inks, but I see it mostly on the nib.  The third is the permanent one:  molecules migrate into the plastic itself, which takes some time.


I know my id is "mhosea", but you can call me Mike. It's an old Unix thing.

I've used all three with no staining in my TWSBIs.  The only stains I have ever struggled with have been from Diamine Grape.  Purples have been bigger problems for me than reds ever dreamed of being.  I used reds between problem purples to help clean.  I don't think you'll have any troubles.

 

Diamine Grape stained the sac of my Hero 612 although the plastic part of it didn't show any staining. I have used the ink in a Lamy converter and my TWSBI 580 with no troubles.

Hmm...in fairness, Grape didn't stain my TWSBI, just my Noodler's Ahab. (Different materials)


Fountain pens are my preferred COLOR DELIVERY SYSTEM (in part because crayons melt in Las Vegas).

I use ASA blue routinely. Nice color, well behaved. No problems. In general, Diamine makes reliable inks. 

 

The others? I don't know...I'm basically a blues-man, having shifted from black to blue-black and all-the way blue.
