A quick water-fastness test of 17 inks on a sheet of Rhodia dotpad paper. They all dried for at least a week prior to when I conducted the test. I rinsed the sheet in warm water, soaked it for half an hour, and then pressed it under a stack of magazines to dry.
De Atramentis Aubergine (4)
Hope Pink (2)
Peach Haze (1)
54th Massachusetts (5)
Bad Green Gator (5)
Baystate Concord Grape (4.5)
Black Swan In Australian Roses (4)
Green Marine (4)
Kung Te-Cheng (5)
Liberty's Elysium (3.5)
Pelikan Edelstein Ruby (2)
Private Reserve Tropical Blue (1)
Notes: I was having feed issues with the pen with which I wrote the Bad Green Gator sample, which is why it is lighter than normal. The way the waterproof Baystate Blue and the more fugitive Baystate Red combine produces a decent imitation of mimeograph printing.
I've given a numerical rating based on remaining legibility.
5 = Unchanged
4 = Changes to color but still entirely readable
3 = Readable, but it is getting hard
2 = If you stand on your head and squint, you just might make something out
1 = All gone!
