Colloidal Glass in Microgravity (image) NASA/Johnson Space Center Share Print E-Mail Caption This is colloidal glass with seed particles (microgravity sample). Aboard the space station, large crystals form unhindered by sedimentation and jamming effects. These experiments are relevant to industrial processes where control of crystal size and crystallization rate is important.
