Bright-field images and movies were acquired using a Leica DMI3000 inverted microscope equipped with differential interference contrast optics and high-resolution cameras: a grayscale Jenoptik Gryphax Rigel and a color FLIR Grasshopper3. Crystal nucleation was observed within hours using a 100X oil immersion objective. For continuous imaging of crystal growth over several days, sealed capillary samples were glued to a 100 mm Petri dish (FisherScientific), immersed in water at room temperature, and monitored using a 10X air objective with minimal light intensity to reduce heating.
