Beautiful flow
I am new to calligraphy.  I ordered several different brands of inks.  Iron Gall ink was recommended by a lady on you tube; her channel is called Acorn something or other. I don't remember the second word.  She had a very comprehensive video on basics.  Not the calligraphy itself so much as the getting ready to write.  She recommended Iron gall ink.  Am I ever glad I saw her video.  I've tried a couple of inks now. Some want to blob off the end of the pen, No matter how many practice strokes, or shaking of the pen.  You think you've got it right and here goes a big blob as soon as you start the down stroke.  So I guess gum arabic or leaving it open for the water to evaporate some is going to be needed.  India ink is very black but gritty and tends to clog the nib.  So this ink arrives, fairly quickly and I open it.  It was wonderful.  First of all the top is wide enough to get the oblique pen in without turning it on it's side to hit the reservoir.  And the flow, OMG no drops, no globs, lasts through a whole line of letters.  It's not as black as some of the others, but this does not bother me.  Being new, I'm having trouble enough trying to learn copperplate.  I don't want to have to be fighting the ink the whole time.  I can't recommend this highly enough.
