Tannic acid is part of the tannin family of compounds, which are used in leather tanning as well as being used as a dye, in ink and paper manufacture, food and wine processing and for medicinal purposes, to name a few. The image was made using polarized light microscopy, which selectively picks up light coming from the crystals in specific directions
