I'm aware that this has been asked and answered a million times on just about any fountain pen forum and elsewhere, but I've sifted through quite a few posts and some of the questions or replies seem to be referring to a variety of things.
I'm considering purchasing a 50ml bottle of my favorite ink (Pilot Iroshizuku Ama-iro) and I don't use a lot of ink. I actually expect the bottle to last me several years.
I'm wondering, if the ink is stored properly (Stored in a dark place (my closet), in a temperature controlled room, sealed airtight), can I expect the ink to last those 5 years with no signs of degradation? 10, 20, 30 years? (If I buy several different colors)
Also, my other question:
Does temperature even matter when storing ink? I say "temperature controlled", but I don't mean constant room temperature. It may fluctuate 10 degrees in either direction, depending on if it's summer or winter.
Thanks in advance for any responses. =)
