Diamine Ink - Blacks

All three blacks are perform well. They have deep rich colour.

I find very little difference in the inks, I have been using the Quartz Black the most and find it to have a good performance in terms of flow and drying times.

 

There is a little more colour depth to the Diamine grey than found with some of the other brands. Looks very good on personal notes.

I am using it in broad nib or stub nib pens, and I am a "heavy" writer in terms of the pressure on the nib. The ink flows and takes more than 10 seconds to dry. This is a little longer than some of the other Diamine colours.
