Belite crystals give six sets of twinned α H ′l‐phase lamellae upon transition from α to α H ′. During further cooling a remelting reaction occurs within the crystals with heterogeneous nucleation and growth of a liquid phase on the lamella boundaries. The liquid, spherical in shape (∼0.1 μm in diameter), is made up of 70 wt% Fe 2 O 3 , 20 wt% CaO, and 10 wt% SiO 2 at 1100°C and vitrified on rapid cooling.
