This is the first time I have used a Schneider pen, it was the only one I could find in 0.05 to match the Uni Pin Fine Line by Mitsubishi Pencil Co, which I have used for a number of years, also 0.05. I wonder if Schneider make them in sepia - that would be nice with the black, too.
If I remember from reading the Schneider spec sheet the pigment is so intense because it is water based - the next experiments will be to see what happens when the red comes into contact with water. I get very excited about the capabilities and properties of my materials.
I decided this will be a birthday gift for a special friend who takes a great interest in my process, so he shall have it with all the work notes and everything.
