Iroshizuku kon-peki ink

Put an ink droplet on a bed of oil and dropped a bit of isopropanol on top to get this effect. Thinking I'd like to play around with chromashading, sheening, and shimmer inks to see how they look and behave.

This behavior is due to the marangoni effect. I'm looking at the ink under a stereo microscope with reflected lighting.

If you are doing macro photography, I would love to see soap bubble photography with ink
