2 x encre sur cuivre Walker's

I have tried dozens of different iron gall inks but always come back to this

I find the Walker's Copperplate ink the best ink to use when writing with the copperplate script. It clearly defines the light and dark strokes without effort.

Best ink I've found for copperplate.

Walker’s copperplate ink gives the finest of hairlines and is a beautiful ink to use with the pointed pen.
