can you please help me to solve my investigatory project..?

Question

my investigatory project is " using charcoal as ballpen ink" that was my investigatory project so can you help me the steps in making that kind of project..

Answer 1

There are pigments that are made from mostly carbon black (pretty close to finely ground charcoal). You can try taking a hypodermic and an almost empty plastic tube ball point cartridge and squirt in that kind of pigment. Use that as your starting point.
