From: On the phenomena of partial crystallization of highly undercooled magnesium silicate molten droplets

Cooling curves for enstatite melt sample A (ΔT = 510 K) and sample C (ΔT = 525 K) under a levitated condition which shows recalescence events on the cooling curve hence indicates the presence of nucleation and subsequent crystallization while sample H doesn’t exhibit recalescence indicating a process of vitrification. Melting point temperature (Tm), hypercooling temperature (Thyp), and glass transition temperature (Tg) of enstatite is shown by a broken line.
