Maybe by this evening, it will have jammed up the feed.
I found the recipe online. Slice a fresh beet in 1/4 inch slices. Simmer covered in 1/2 cup water, until tender. Cool. Add 1 tablespoon vinegar. The only things I did that were not called for in the recipe, were to peel the beet, and to strain the ink through a paper filter.
The result is a pleasing red-violet that flows nicely.
The pen I used has a medium nib with a kangaroo design and the word "Katelina" on the steel nib. At the bottom of the pen, on a silver base cap, is "Katelina 6618". It has been trouble with more conventional ink - a nice fat line, and five or ten minutes later, dry. I expect it may work better with a watery home-made ink.
