Polarized Microscopy of Chemical Crystals by Doug Craft

These are images taken of chemical crystals using a Nikon polarizing microscope from 2004-2006. I prepared slides of melt crystals of phenol (carbolic acid) and benzoic acid, and precipitation crystals of ascorbic acid and potassium acid phthalate. Crystal will form vivid colors in a polarizing microscope as you can see this video. The music is a piece called “Impermanence,” I composed in 2011 using Acid Pro.
