Supercooling - Kareido

…also called dendrites. The solidification of a molten liquid begins when the temperature of the liquid is somewhat lower than the melting point (the difference between the two temperatures is called the degree of supercooling), but dendrites form when the degree of supercooling is large over a wide range. In such cases, the latent heat of solidification can be continuously absorbed by the molten liquid, allowing the solid phase to grow three-dimensionally. …
