So oil paint was a hot ticket in the art world of the mid-1400s. If you’re Johannes Gutenberg and you need to figure out how to get ink to stick to your metal type, that oil binder looks pretty good. He developed an oil-based ink that’s thick, sticks to metal and can be applied evenly. Gutenberg created a blacker-than-black pigment by mixing carbon (charred bone), graphite, copper, lead, titanium and sulfur. The graphite and copper give the ink sheen (I’m guessing it’s the orangey copper that’s powdered somehow—like when you saw through a copper pipe with a hacksaw—rather than scraping the green corrosion).
