I know this is not an infrequently posted topic, but I am having trouble finding the answers I need. I recently purchased a celluloid pen (Visconti Wall St LE) and I am concerned about maintaining the celluloid as well as possible. Up until now I've been using PR DC Supershow Blue as my standard blue ink, but it is quite saturated and I have no plans to put that in the Visconti. I do need a replacement blue though, so I was curious to see how safe some of my options were.
I am aware that Pilot and Sailor inks tend to be quite basic and may be able to damage Celluloid. I am especially concerned given that the material is stacked and any degradation seems like it could cause leaks. Unfortunately, I quite like Iro Kon-Peki and Sailor Tokiwa-Matsu. Should I avoid using them in this pen?
I was planning on picking up either some Waterman Serenity/Florida blue or J.Herbin Eclat Saphir. I'm assuming these are both safe to use given their reputation. I was also looking at Omas Blue, but I can't find much on how safe it is (although it does seem to be quite acidic), does anyone have some advice here?
I apologize for the rambling post, and thanks for the help!
