I think that's a slippery slope. There is hardly an ink anywhere that someone has not claimed has caused Extremely Unpleasant things to happen to their pen.
Why do you think such a warning label is needed? No warning label will protect clueless users from their own stupidity, laziness, carelessness, or inability to exercise simple, basic maintenance. As witness the people who still smoke in spite of decades of warning lables.
Bill,
I know little about pens, so only hesitantly I'll say I think that's a bit unfair. You don't expect ink to damage a pen any more than you expect the oil in your engine to cause damage - yes, I accept you have to change the oil regularly. Pens are designed to run on ink, whereas the human body could be claimed not to be optimized for cigarettes. If you've used a certain readily available ink for many years and suffered no apparent damage you're not likely to realize that Brand X's cartridges are OK but their identically named bottled ink is not.
That's my layman's perspective. But can I ask you for your opinion on specific questions: is it OK to switch between commonly known inks for different makes of pen: specifically, is it fine to use Pelikan 4001 in a Parker, Waterman, or Sheaffer; Waterman in a Parker, Pelikan, or Sheaffer; modern Quink in a Pelikan, Sheaffer, or a Waterman; Skrip in a Pelikan, Waterman,or Parker? I think that's exhausted the combinations between those four brands! And one more, if a pen is known to suffer corrosion problems at the gold section end (Le Man/Patrician/ Rhapsody) is any of those or other inks going to be a best bet for delaying or preventing the process?
Thanks,
Thomas
My point in the post to which you object is that there is hardly an ink in the world that someone, somewhere, sometime, has not claimed caused damage to his/her pen. The problem with warning labels is that once you put one on your product, all the plaintiffs show up wanting to take your money, your company, and your good name because they claim your warning did not address their specific situation.
The only warning label that would make sense to me is the "common sense" warning: "Caution: This bottle contains ink, a chemical solution that stains things, including human skin and anything else that it contacts. It evaporates and makes clogs in pens, and it may react with pen materials in ways the manufacturer cannot predict. It will make you sick if you drink it, and it is harmful if you get it in your eyes or any other bodily orifice. All use is at your risk."
