The Fountain Pen Physicist tackled a question on lots of pen users’ minds: How lightfast are my inks? And in true scientific method, there are samples of both ambient and sunlight samples compared to the originals after three months of exposure. I hope there will be follow-ups at 6 months and a year to see if any further changes occur.
It looks as if more tests are being performed as well as waterproofiness. What a fabulous resource!

Awesome idea. I actually wanted to do something like this with my inks but I put it on the back burner. I love the idea of very long term tests.
I like to see that Noodler’s inks (at least the darker ones) seem to hold up fairly well
Very cool experiment. I too would be interested in seeing the results 6 months from now.
