Shake the bottle?

[maryannemoll]

I'm going to chime in here by saying that an awful ink, Noodler's Rome Burning, when unshaken, looks a horrible mustard, and bleeds through the paper (even 85g Clairefontaine). Shaken, it looks darker, like the Irozishuku Ama-Iro, but still bleeds through paper.

 

How about Rouge Hematite? When unshaken, the sheen is diminished. But when shaken, it looks glorious. I don't want to waste my money. You're correct there, imahawki.

 

So I'm all for shaking.

I have found that all the Noodler's Bulletproofs require agitation to re-suspend them. They contain dyes that are not particularly soluble and how knows what other strange things, but I've never had any clogging problems in pens that could not be solved by simple flushing, even in a very cranky Parker 61 with a damaged filler (I ended up taking it completely apart and unrolling the plastic sheet to get it cleaned and working -- the rolled sheet had been jammed into the bottom of the filler and squashed together, once I flattened it out the pen worked (and works now) just fine).

 

Nothing in the Noodler's inks precipitates into water insoluble material so far as I can tell, so I shake them up or at least agitate them until whatever is on the bottom of the bottle is suspended before filling a pen.

 

The normal agitation of carrying and using a pen keeps the ink stirred up well enough for regular use.

 

I find that the colors are wrong and very light if the ink isn't stirred up properly. Just the nature of the material, works fine for me.

 

SITB is a different subject -- I've had to toss a nearly empty bottle of Skrip Blue-Black when it grew slime.

Some organic dyes are highly saturated solutions (Diamine Pumpkin?) so that crystals begin to form in them. Shaking the bottle might help redissolve them, but I don't do that. Doing so is inviting have the solution re-crystalize in my pen. I doubt that the agitation makes the ink much brighter orange, so letting the crystals say put on the bottom of the bottle is fine with me.

Not true. If anything ever crystallises out of a solution, then that is due to the fact that the solution (usually originaly at a somewhat higher temperature) will precipitate in the form of crytals. I.e. shaking won't do anything except redistribute the crystals into the solvent. The whole liquid is no more a "homogeneous solution" but NOW only a suspension of particals. Amorphous precipitates are -- for a solution like ink -- even more "dangerous". That is, don't shake! I's not going to do you (or your pen) any good.

Hmmm... When my film developer and fixer sit in bottles, they form crystals on the bottom of the bottles. So before I use them, I place them on a stirring apparatus with a magnetic bar, and after 10 minutes, I can get the crystals to re-enter the solution. No heat, just spinning.

 

When I first make a jug of D-76, I sometimes have to spin it for an hour to get the crystals dissolved. They don't readily dissolve when nearing saturation. It just takes a while.

 

Is Diamine filling bottles with Pumpkin ink + crystals? If so, they need to just give us the ink. Leave out the crystals.

...or, centrifuge the crystals out of solution and keep them in a cool, dry, dark vessel as an extract for later use. Like on a plane.

If dyes are so saturated that they settle out of solution, I take it as a sign that I can dilute the ink a bit. In the case of some Noodlers inks, a bit of dilution actually gives an improvement in colour.

I use several Noodler's bulletproof and near- bulletproof inks. They do separate if left to sit for a long time. Before filling a pen with them, I invert the bottle several times until the ink mixes again. I don't "shake" the bottle; doing so creates too much foam and I can't get a good fill with foam. Before using one of the pens, I invert the pen several times to remix the ink inside. I never flush my pens except when changing colors. I have had a Platignum Silverline filled with Upper Ganges Blue, a Sheaffer Fineline filled with Fox Red, a Sheaffer Vac Fill filled with Green Marine, and a No Nonsense filled with Legal Lapis. They have been filled like this for a couple of years now, and none has ever clogged.

 

If you folks are getting clogged pens, you don't use them enough.

I can tolerate a few crystals in my Diamine Pumpkin. What drives me nuts is having a 2-lb bottle of amber honey turn into 1.5 lbs of sugar crystals.

Put the jar in a pan of water on your stove. Heat the water to about 130 - 135 F. The honey will liquify again. I used to have honey in 55-gallon drums. They were a little harder to deal with.

Gastronomically speaking, easier to deal with
