I still think that there is an issue at times with different inks combining and causing a problem. It is almost impossible to rinse a pen 100% clean, there's always a little hint of some color of ink left lurking in the sac regardless of how many times you rinse it out.Let's see - if I caught all the different posts, this pen has had the following inks inside it with the same sac of unknown origins: Sheaffer Skrip Blue, Aurora Blue and Noodler's Black. Also whatever ink Ron used to test the pen when he originally restored it.How old was that Skrip Blue? Sheaffer had some problems recently with Slovenian production of Skrip that I believe is resolved now, but if it was a "current" production bottle of Skrip Blue, it might have had an issue. If it was "vintage" Sheaffer blue, perhaps something had gone off in that. What other pens had been filled from those bottles of Skrip Blue, Aurora Blue and Noodler's Black - did they have any leftover ink that could have been introduced unknowingly into the bottles?I use all of these inks and a bunch of others, too. The only sacs I personally have seen melt down were from "that" bad sac batch a few years ago (let's not go there!) and that was limited to Snorkels.I've been using Noodler's Black since BEFORE it was even introduced to the public in all sorts of pens with sacs and all sorts of other filling systems and I just haven't seen any issues with it.We need to analyze further and not jump to conclusions about thisSam
