How do you use Glass dip pens?

I just recently purchased a Glass dip pen to add to my collection, and i thought they were supposed to be smooth wrinting instruments, i find it to have a kind of scratchy effect, and the ink dries up really fast on the tip, mine has spirals on the tip for “larger ink capacity” but so far that claim doesnt seem to be holding up, can someone tell me how to use it if there is a special way, or do i just use it like a fountain pen? Thanks
