Having not used BSB, I've never thought of any ink that needs to be cleaned out of a pen daily, nor weekly.
I normally have ESSR in one of my pens, right now a Pelikan 120 gold plated F.
I did a 46 paper survey with some 17 nibs of this and that width and flex, Nail, regular, springy, semi-flex, maxi-semi-flex/flexi and easy full flexible nibs.
Some papers turned quickly, others slower. Some went gray on this or that paper; depending on the nib.
A number had a blue tinge, that stayed for a week. Many turned darker than I then wanted.
That is still a blue-black, if one looks hard enough at it. Some are gray...still.
My 35 year old Eaton Corrasable 16 pound typewriter is the only one that went on blue and stayed blue. Though after some 2 or 3 months it appears to me, the blue there too has darkened.It is still more towards the blue side.
What surprised me; is some of the curing to 'black' cured back to a blue-black.???? Could be Lapis was right, and it was bluer than I then wished, but 'could not see'.
Now I am much happier with the ink, than before in I wanted a Blue-Black, not a Black-Blue, or a Black which many seem to want.
Many people seem to have different results. The nib, width and flex, and if it's Wet or Dry makes a difference, on many papers. It is a paper driven ink.
I'd complained about it being too black, now I see more blue, on more papers.
Then again, I'd only checked the papers after two weeks, where some got darker than I then wanted.
Could be I was mistaken to how dark it changed, in I liked the bluer tinge of it in the beginning.
I like the tone I got with many of the nibs more now than I did after the original two week curing.
Another fella Lapis wanted it to turn black and it was too blue for him, and I wanted some Blue to my blue-black.
We exchanged ink bottles, and both of us got what we gave away.
I have two maxi-semi-flex/'flexi' nibs in Fine that I used. One turned up rather gray on most papers (Osmia 883 F, the other much more blue-black; a Rupp F nib in a German piston 'Clipper'. The gray has much to do if the nib is dry or wet as far as I can see, now that I took a look at all 46 pages. And am looking for the gray, that I don't think I looked at much when I did the survey.
My Cross Townsend nail M was gray on most papers, could be that is a dry nib.
Many thanks for your continued contributions to this thread.
I tend to agree that ". . . I've never thought of any ink that needs to be cleaned out of a pen daily, nor weekly." However, I've not used an FP ink such as ESSRI before!
As my personal practice does not encompass leaving ink in a pen for extended periods, I can only suggest how I would go about doing so with ESSRI. Post № 35 Clearly, that is not necessary for all ink+pen combos, but as I change my personal use pen+ink combos on a document-by-document basis, I generally clean my pens after each document. Quite possibly I erred on the side of caution when making my choices regarding handling of ESSRI - rather that than read of it being held accountable for the disappearance of someone's Volvo.
Of course each person can and should make their own choices; and I for one would be more than glad to read that any number of perceived/possible risks are shown to be unfounded, and practices can be streamlined. Yet we have the suggestion from Member pharmacist that the clean-up regimen be expanded to include the use of diluted vinegar. I think that is a huge benefit of FPN: freely sharing our thoughts, knowledge and experiences, so adding to the enjoyment of FP use.
Ah, the 'Blue-Black Black-Blue Blue-Grey Gray-Blue' conundrum. I think you were spot on in describing ESSRI as 'sneaky'. Though these days I fondly consider it to be 'mischievous'. To better show the subtle colour/s and tonal range of the ink, a true Black was included in the Review samples, (wee dots of Black sumi-e ink, close by the dimension reference at the bottom of some pages, and the T in the Swabs.)
Quite frankly I am rather surprised that more than a few people use ESSRI on a routine basis - not as an ink-fuelled mystery tour.
