Reading this thread on FPN about Noodler's Black ink, I wanted to make a similar test with my current favorite ink (with Pharmacist's Iron Gall Blue-Black), Noodler's Polar Black.
So I decided to try a similar water resistance test. Similar but not the same, because for example I have no newspaper near me today :)
I've used 4 kinds of paper : Rhodia Dot Pad, unnamed office copy paper, PostIt note and a page of glossy magazine paper.
Here you have the samples after writing :
Here the four samples after being submerged in water for 10 minutes :
And here after some torture...
The ink is wonderful in all samples besides the glossy paper. Why doesn't it perform great on it? If I understand right, it's because it bulletproofness comes from bonding with cellulose in paper, and in glossy paper there is a layer impermeable between the ink and the cellulose, bonding is way limited.
I really love this ink, my ink of choice (with Pharmacist's Iron Gall Ink) for everyday use!
I've posted this review on the same thread in FPN.
