crystallized Vitamin C_27
I dissolve vitamin C (ascorbic acid) in water and pour a thin layer into a petri dish or on a piece of glass. Within minutes you can watch the crystallisation grow, as the liquid dries. (Check the internet for detailed instructions.) The colors appear when you watch the process under cross-polarized light from underneath.
You can influence the pattern formation through changes in temperature. My pictures show mostly an area of a quarter square inch. My favorite lens is the Canon MP-E 65mm f/2.8 1-5x Macro
