In this study, hydrates growing from micro crystals on a glass cooling surface in supercooled aqueous TBAB solution were observed at concentrations of 20 and 40 wt % and supercooling of 2 ~ 6 K. In this experiment, two types of crystals were observed: type A at 40 wt % and both type A and B at 20 wt %. Crystal of type A at 40 wt % grew at an almost constant speed immediately after the crystals appeared because the concentrations of solid and liquid phases were almost equal, but the growth speed decreased with growth at 20 wt %, when the liquid phase concentration was lower.
