Here’s an Ambassador fountain pen with a fantastic “Warranted” 14k nib. Unfortunately, while it’s one of my favorites to write with, it got shoved to the back of the drawer.
So when I pulled it out to use it, the once vibrant and beautiful Diamine Sargasso Sea had , well, congealed into one big clog.
So let this be a lesson for you, flush often, flush well.
Ouch! Soak, soak, soak. Diluted ammonium solution if water is not enough (but I think it will be). I just hope the nib will be OK.
