Using Coffee As Ink?

[SeeksAdvice]

Coffee also molds. Just all around not a great idea IMO.

As a serious coffee person (2 ECM's, a Macap, and a roaster), I'd never put this in my FP's due to its intense acidity, caramelisation, and tendency to dry to a solidish hunk.

 

But, here you are, with a dip nib. Hate to say it folks, but that 'ink' is dry and it has crazy sheen/shine. It's also tangibly 3-D on the paper.

That looks great. Very nice handwriting too!

One month ago I bought a nice pen in a web site of purchase. The seller has no idea of the nib width and he did no have ink at home, as well as, he lived in a little town without stationery shop. To resolve the problem, I suggested them what use coffee for write one sample. Few minutes after I knew the nib size.

 

At present, the pen works in perfect order.

For use with a dip pen you could make extra strong coffee or let it evaporate a couple of days. Try adding some liquid gum arabic to thicken it up.

 

Love the sample from Intellidepth!

 

Like many others here, I don't think it's worth it to risk ruining a fountain pen, but with a dip pen, the field is open. I do believe I'm going to write my next letter in blood.

That writing sample was with coffee? That really looks amazing. I might try to sacrifice a dip pen nib...
