Hello, I have a few questions regarding one of my favorite inks...R&K Alt-Bordeaux. Over the past few months I've been using it and observing some weird characteristics for such a supposedly well behaved ink. For starters, it appears to slightly fade/change color over the course of a few hours, turning from a purplish burgundy to a rosy, raspberry-like color...which I also enjoy a lot, but which is lighter than the original. Secondly, and more disturbing, is the fact that this ink seems to develop nib crud after a few days, regardless of the pen being used or not. However, I found that I could clean the nib with just a dry paper towel, and had no clogging (so far). Has anyone else experienced these things with this particular ink? Thanks and have a great 2015!
