Found this bottle of Sheaffer Skrip Ink Jet Black ink in the house. It's probably 20+ years old but no clue from what time exactly.
Has a thin metal cap, it's all crusty on the threads.
The inside has an ink well made from glass.
This is the angriest ink I have ever seen.
Following two pictures are done on Claire Fontaine paper. Usually you can leave whole pools of ink to dry on it without it getting through the surface. But this ink burned right through!
back:
Small writing test. The ink is so fluid that it overfills the feed. If I don't absorb the excess with tissue every 20 seconds whole droplets will spill onto the paper. I don't know if it was always like this or if it's because it has been sitting there for decades.
Small drawing test. The ink is feathering which other inks usually doesn't do on this sketchbook.
Washing nib in water reveals red undertones. Could also be seen in the bottle images.
Pen used for testing: FPR Indus with ultra flex nib.
Yep, you never know what kind of wild stuff they threw in back then. By the same reasoning, 30 years from now we will be saying "I can't believe they really put xxx in yyy".
I'm saying this because lead is toxic, and since this is ink it'll easily get on your hands and might enter your blood and you'll get poisoned
Thanks for your concern. I only used this ink once to try. What I meant is that we might have some things in our current products that will be considered toxic in a few decades, just like old stuff might have lead in it which we now think is unhealthy. Just a thought that bubbled up.
Yeah that's how it usually works, I'd be more concerned if they didn't find anything
