I've recently heard that Waterman's Florida Blue is known to clog pens. Is this true? Any one know anything about this? If yes, then is there something that can be done? Perhaps blending with another ink?

Thx.

Who said it clogged pens? Usually Waterman inks, especially Fla Blue are used to help a pen with flow problems and/or remove residue of old ink after you have flushed and flushed and flushed.

Perhaps someone misspoke or mistyped. Look at the reviews of Waterman Fla Blue.

I think Waterman Florida Blue is one of the best behaved inks ever!

No way. The only blue I've heard that clogs sometimes is Parker Penman Sapphire.

Anything will clog if you leave it in there long enough

What Garageboy said. I generally flush my pens once a month just so I have an excuse to fondle more of them.

On the contrary, W Florida Blue is known to be the Holy Grial of inks. No better one for priming, solves and dissolves problems no other can, an all time great blue color, runs just right, not too liquid not too thick....If there wasn't one it would have to be invented.
If you read the forum you will find that, as a matter of fact there are several inks that are prone to clogging pens, even whole brand series. All Waterman's are well reputed for the contrary. In all colors, they are one, if not the main, best behaved inks in the market. Also, one of the oldest makers around.

Flushing pens every color change or every 6-8 weeks is recommendable, in all pens and inks. But I've had pens left to dry in WFB for over a decade that recovered their "as new" status just with a few hours of flushing and rinsing. If you happen to find other pens inked with less friendly inks, the solution is ultrasound and lots of cleaning or nothing, and that, in the best of cases.

Buy it. Try it for yourself, and compare to others. And come back and tell us.

What a nasty, untrue rumor... where did you hear it?

You definitely have to put the source straight...

Hard to imagine! What pen did it clog?

Nah..........this is one of my most used inks in all of my brands of fountain pens and is one I use to judge all others.

Dodgy rumour circulated by someone who has filled his pen with another brand and got confused ????

Waterman Florida Blue DOES NOT CLOG PENS.

I don't know what you heard, but it was probably either a case of a pen being set aside for weeks or months -- which can cause ANY ink to clog -- or a different ink altogether, such as Parker Penman, which is indeed known for clogging pens.

(Caveat: I have never personally used Parker Penman, so I rely only on what has been written here and other fountain pen websites as the basis of my statement about Penman clogging pens. I suspect that, with proper and periodic cleaning, even Penman would work in most pens.)

I consider Waterman inks to be the best you can find. Blue-Black is my favorite, but Florida Blue follows right on its heels. Good flow, good lubrication, good color, nonstaining, nonclogging. These are superb inks. As Garageboy says, any ink will clog any pen if you leave it in there forever, filling and filling and filling without ever cleaning the pen.

Thanks all. Very much appreciated. I will leave the source un-named.

d.

Someone from New England started this rumor? Naaaa, I don't believe it!

There's no point in being nasty about it.

I keep Waterman Blue around just for those "is this thing on?" tests. I don't generally use it as an ink, but I do use it as a way of ruling out variables for pen performance.

Been using this ink for over 16 years with no problems whatsoever...

Sadly, the bottle of Waterman Florida Blue that I had until last week, was causing my two Phileas pens to clog up within 36 hours. Several times I let them soak in water for 24-48 hours, and the same thing happened again and again. Last week, I opened another bottle of Florida Blue, and so far it has been seven days, and both pens are writing very smoothly with no clogging issues. Hopefully, this was an isolated case of a bad bottle ink.
