Hello! I'm a new user. I've created two videos showing the effects of ink under a microscope. The first one, "Fountain Pen Ink Flow Under a Microscope" is a video showing the ink flow of various inks from various pens under various (10-40 power) zoom. The second one, "Up Close and Personal With J. Herbin Rouge Hematite" shows the golden sheen coming out of the ink at various magnifications and it's pretty interesting to see! If you're interested, check them out! Got any opinions or ideas, let me know! I'd love to do more videos on the subject. edit: Here is a gif showing the Rouge Hematite in action! Videos are inline below.
