I gentlemen called me yesterday asking for help. He does a lot with ceramics and uses a felt pen but has come up with his own ink mixture - he is having trouble finding an "eye dropper" that will allow his thicker ink formulation to move/be used. And wanted to know who might have some experience to help hm make a custom dropper. I told him I would reach out and see if anyone had any specific knowledge/experience in this area. Let me know if you would be willing to talk to him and I will send you his phone number.
Thanks for your help.

We made custom eye droppers in chemistry class. Draw the glass so the tip was a certain size. Test it to see how much liquid a certain number of drops would produce. Have him check with a chemistry teacher at a school or university.
 
Is the issue that he cant get the ink to draw up into the eyedropper or that once he fills the eye dropper the bulb will not exert enough pressure to squirt the ink out?
 
I would have him start here. They are a restoration company but would have a wealth of experience to point him in the right direction.

I suggest that he starts by testing whether or not the ink will function with a dip pen - the type where you dip the nib into a bottle of ink and write till it's all used up then dip again.

It's a fundamental test of whether the ink works with a nib at all, without introducing the challenges of getting it to flow through the feed of a fountain pen nib. If the ink he makes is too viscous for capillary action to pull it along the slit to the tip of the nib, it's not going to work at all.
