Hello everyone,
I've been back on FPN for one or two weeks now, and am really loving the knowledge that's still being shared here. I'm currently learning more about urushi pens, and surprisingly, there is one topic I haven't seen explicitly discussed on this forum (or elsewhere).
What inks are more "safe" for urushi on temporary contact?
I understand that leaving ink (or any liquid) on urushi for a prolonged period of time will likely damage it, regardless of its composition. However, I suspect there certainly are inks that will create staining and other issues more quickly than others. I'm therefore trying to find out which inks are the least dangerous for urushi.
My initial guesses on unsafe inks are pigment (as opposed to dye) based inks, Noodler's lubricated inks, and "permanent" inks of any kind.
My initial guesses for safe inks are the standard fare: Pilot/Namiki, Waterman's, Pelikan, etc. (However, I have heard iroshizuku can cause problems -- is this true?)
I'm looking forward to what people with experience in the matter have to say. Thanks in advance!
