Hi Henry

I do have my old Faber-Castell pen set which still has a bottle of black
drawing ink.  I bought it in the early 70's only to discover the firm I
joined had a wonderful drafting department which used pencils and took a
dim view of anyone requesting ink work.  I got over the ink matter
quickly and let them do my drawings.  The finest point in my set is
0.1mm and the largest point is 0.8mm.

I will run a test with my ink first.  I recall vividly using one of the
pens when the set was purchased.  Everything went as expected until
clean-up time.  It took a long time to get the pen clean, I had ink
spots on the wall, my clothing and everything within sight.  My wife
yelled something that shouldn't be repeated but it included "ball point
pen".

I've never used lampblack, it sounds messy.  Did you purchase or brew
your own?
