I ran across this review on the Amazon website where they sell Daler-Rowney Calli ink. I'm just passing this along to anyone thinking about using this ink in a fountain pen:
"While I think this is a really nice dip pen ink, it shouldn't be used with calligraphy pens such the Lamy Joy, or anything with a reservoir. I contacted the manufacturer who said that while it will work in a fountain pen, Calli ink may cause the reservoir to rot. So it certainly isn't safe to be using in fountain pen. It would of been nice if this information was included on the bottle, or at least a little warning like 'not safe for fountain pens,' since I have been using these calli inks in my pens for over a year now.
