26. At typical crystal growth velocities of meters per second, the time lag between nucleation and completion of growth in a single emulsion droplet is on the order of a microsecond. This estimate is not substantially changed by the fact that these materials form platelike structures during freezing. Even though the formation of plates suggests slower growth along certain crystallographic directions, the ratio of the slow rate to the fast one would have to be less than (Formula presented) to have an effect on the experiments.

28. Based on the estimate that the standard deviation for the droplet diameter is about 0.1, the standard deviation for the emulsion droplet volume distribution should be about 0.3.
29. While the required active fraction is quite small, this is not unexpected in light of previous research—see Ref. 5.
